Thermal Bow Hunting for Hogs: The Complete Guide to Night Hunting with

Introduction: Why Thermal Changes Everything for Bow Hunters

I'll never forget my first thermal bow hunt for hogs.

For fifteen years, I'd been a traditional bow hunter—sunrise sits in tree stands, careful wind management, endless patience waiting for daylight shooting windows. I was good at it. I harvested 8-12 deer annually and the occasional hog that wandered into range.

Then I mounted a thermal scope on my crossbow.

That first night hunt, I took three hogs in four hours. Not because thermal made me a better archer—my shooting skills were unchanged. But because thermal gave me access to an entirely new hunting dimension: night, when hogs are most active, most predictable, and most vulnerable.

Five years and 200+ thermal bow-hunted hogs later, I can say this with certainty: thermal imaging is the single biggest advancement in bow hunting effectiveness since the compound bow itself.

Today, I'm sharing everything I've learned about thermal bow hunting for hogs—equipment selection, shooting techniques, range management, ethical considerations, and the specific challenges of combining thermal optics with archery equipment.

If you bow hunt hogs (or want to start), this guide will transform your success rate.

Why Hogs + Thermal + Bow = Perfect Combination

Let me explain why this specific combination is so effective.

Hog Behavior Makes Thermal Hunting Ideal

Hogs are primarily nocturnal:

70-80% of feeding activity occurs between dusk and dawn
Daytime hogs are wary, bedded in thick cover, difficult to approach
Nighttime hogs are confident, feeding openly, easier to pattern

Hogs have predictable thermal signatures:

Large body mass (150-300+ pounds)
Sparse hair coat (excellent thermal emission)
15-20°C temperature differential vs. nighttime environment
Easily distinguished from deer, coyotes, and other game

Hog populations support aggressive hunting:

Invasive species in most of North America
Year-round seasons, no bag limits in many states
Population control is conservation priority
Multiple harvests per night are ethical and encouraged

Why Bow Hunting Hogs (vs. Rifle)

Stealth advantages:

Silent shot (doesn't spook entire sounder)
Can harvest multiple hogs from same group
Works in suburban/residential areas with noise restrictions
Neighbors don't hear—essential for permission land

Safety advantages:

No bullet travel concerns (arrows stop in target/ground)
Safer near structures, livestock, property boundaries
Better for hunting near roads or developed areas

Challenge and satisfaction:

Higher skill requirement = more rewarding
Ethical close-range hunting (30-40 yards typical)
Complete utilization of meat (less tissue damage than rifles)

Why Thermal Makes Bow Hunting Viable at Night

Traditional night bow hunting problems:

Can't see target clearly enough for shot placement
Can't track wounded game in darkness
Safety concerns (target identification)

Thermal solves all three:

Crystal-clear target visualization (better than daylight in some conditions)
Immediate blood trail detection (wounded animal shows temperature change)
Positive species identification before drawing bow

Result: Night bow hunting becomes not just possible, but more effective than daytime hunting for hogs.

Equipment Setup: Thermal Scope + Bow Configuration

Getting equipment right is critical. Here's what works (and what doesn't).

Choosing the Right Thermal Scope for Bow Hunting

Resolution requirements:

Minimum: 384x288 (adequate for close-range shots under 40 yards)
Recommended: 640x512 (superior target detail, better shot placement confidence)
Overkill: 1280x1024+ (unnecessary for bow hunting ranges, expensive)

Why 640x512 is ideal for bow hunting:

Clearly shows anatomy at 30-40 yard shooting distances
Distinguishes vitals from shoulder blade/bone
Sees arrow flight and impact point
Tracks wounded animals with precision

Magnification needs:

Base magnification: 2-3x (field of view for close shots)
Digital zoom: 4-6x capability (for distant scouting, not shooting)
Bow hunting is close-range—you don't need extreme magnification

Mounting options for bows:

Option 1: Weapon-mounted thermal scope (crossbow primarily)

Mounted directly on crossbow rail (Picatinny or Weaver mount)
Provides aiming reticle for shot placement
Best for crossbows (longer, stable platform)
My recommendation for crossbow hunters

Option 2: Helmet/head-mounted thermal monocular (compound bow)

Thermal monocular mounted on helmet or headband
Keeps both hands free for bow operation
Better for compound bows (draw/anchor requires hand mobility)
My recommendation for compound bow hunters

Option 3: Handheld thermal + bow sight (hybrid approach)

Scan with handheld thermal monocular
Aim with illuminated bow sight or laser rangefinder
More cumbersome but works
Budget option for compound bow hunters

My Thermal Bow Hunting Setup (What I Actually Use)

After five years of testing, here's my refined setup:

Crossbow Setup (Primary Hog Rig)

Crossbow: Ravin R29X (400 FPS, compact, accurate) Thermal scope: GTGUARD Sentinel Pro 640x512 Mount: Warne Maxima Crossbow Rings Arrows: 400-grain carbon with fixed-blade broadheads (Rage Hypodermic) Effective range: 20-45 yards (I don't shoot beyond 50 yards even with thermal)

Why this setup works:

Crossbow provides stable platform for weapon-mounted thermal
640x512 resolution shows clear anatomy at 40 yards
Fast arrow speed (400 FPS) reduces shot angle calculation complexity
Fixed-blade broadheads (no mechanical failure in cold weather)

Sight-in process:

Zeroed at 20 yards
Confirmed at 30 yards and 40 yards
Thermal reticle shows precise holdover for each distance
Practice extensively before hunting (thermal aiming feels different than daylight)

Compound Bow Setup (Secondary/Challenge Hunting)

Bow: Mathews V3X (70 lb draw, 29" draw length) Thermal: AGM Venom helmet-mounted monocular Bow sight: Black Gold Ascent Verdict with LED illumination Arrows: 450-grain carbon with fixed-blade broadheads Laser rangefinder: Vortex Ranger 1800 (thermal detection, laser confirms range) Effective range: 15-35 yards (closer than crossbow due to complexity)

Why this setup works:

Helmet-mounted thermal keeps hands free for draw/anchor
Can scan environment without moving bow
Illuminated bow sight provides aiming reference
Laser rangefinder confirms exact distance (critical for compound bow trajectory)

The challenge: Compound bow with helmet-mounted thermal is HARD. You're:

Scanning with thermal (left eye)
Drawing bow (both hands)
Aiming through illuminated sight (right eye)
Maintaining anchor and form

But it's incredibly rewarding. I've taken 30+ hogs this way. When it works, it's archery at its finest.

Shot Placement with Thermal: What You Actually See

Understanding hog anatomy through thermal imaging is critical.

Thermal Anatomy of a Hog

What shows up bright (warm) on thermal:

Core body mass (thorax, abdomen)
Head (brain, jaw muscles)
Legs (large muscle groups)

What shows up cooler (less bright):

Shoulder blade (bone, less thermal emission)
Spine (bone structure)
Snout (cartilage, cooler than body)

Critical observation: The vital zone (heart/lungs) appears as uniformly warm area in the chest cavity. You want to place your arrow in the center of the warmest chest signature, avoiding the cooler shoulder blade area visible on thermal.

Ideal Shot Placement Zones

Broadside shot (easiest, most ethical):

Aim for center of warm chest signature
Slightly behind the shoulder (avoid shoulder blade)
One-third up from bottom of chest
This hits lungs/heart, provides quick, humane kill

Quartering-away shot (good opportunity):

Aim for opposite-side shoulder
Arrow angles through vital organs
Visualize exit point through thermal
Slightly tighter margin for error

Quartering-toward shot (risky, avoid unless experienced):

Requires arrow to penetrate shoulder
High risk of bone deflection
Only take if you're confident and hog is close (<25 yards)
I generally pass on this shot

Head-on shot (only for experts, small target):

Extremely small kill zone (brain/spine)
High risk of wounding if placement is off
I don't recommend this for most hunters

Rear/Texas heart shot (controversial):

Arrow enters hindquarters, travels forward to vitals
High risk of gut shot if angle is wrong
Not recommended for beginners
I only take this shot if hog is walking directly away at close range (<20 yards)

Range Estimation and Trajectory with Thermal

Bow hunting demands precise range knowledge. Thermal imaging changes how you estimate distance.

The Range Estimation Challenge

Problem: Thermal imagery doesn't provide the same depth cues as visible light.

No shadows
No texture details
Size-based estimation is harder

Solution: Use laser rangefinder ALWAYS.

My process:

Detect hog with thermal scope/monocular
Confirm species and count (how many hogs, any deer?)
Laser rangefinder to exact distance
Adjust aim based on known trajectory
Draw bow only when ready to shoot (minimize hold time)

Trajectory Compensation

Crossbow (flatter trajectory, easier compensation):

20 yards: Aim dead-on (zeroed distance)
30 yards: 2-3 inch holdover (depends on arrow speed)
40 yards: 6-8 inch holdover
50 yards: 12-15 inch holdover (I avoid shots beyond 45 yards)

Compound bow (more arc, requires more compensation):

20 yards: Sight pin adjusted for this distance
30 yards: Different sight pin or holdover
40 yards: Significant drop compensation
Beyond 40 yards: I don't shoot hogs with compound bow at night

Practice is essential: Shoot your thermal-equipped bow extensively before hunting. Arrow trajectory looks different through thermal reticle.

Hunting Strategies: How to Actually Find and Approach Hogs

Thermal gives you detection capability. Strategy determines success.

Scouting and Pattern Identification

Daytime scouting:

Identify hog sign (rooting, wallows, trails, rubs)
Note feed areas (agricultural fields, oak groves, crop edges)
Identify bedding areas (thick brush, creek bottoms)
Map travel routes between feeding and bedding

Thermal scouting (dusk reconnaissance):

Glass fields and openings 30 minutes before dark
Identify hog emergence patterns (where they enter fields)
Count hogs (sounder size, age distribution)
Note feeding patterns and movement direction

Pattern recognition: Hogs are creatures of habit. Once you identify their pattern:

They'll use same trails repeatedly
Feed in same areas nightly (until food source depleted)
Emerge at predictable times (usually 30-60 minutes after sunset)

Ambush Setup (Most Effective Strategy)

Tree stand hunting (my primary method):

Position downwind of expected hog travel/feed area
15-20 feet elevation (hogs have poor upward vision)
Clear shooting lanes at 20-35 yards
Thermal scan eliminates need for visible light

Ground blind hunting (alternative):

Position near active feeding area or travel corridor
Ensure good shooting windows
Thermal allows you to see hogs approaching from any angle
Scent control is MORE critical (ground level = better hog scent detection)

Spot-and-stalk (advanced, exciting):

Glass with thermal from vantage point
Identify feeding hogs
Plan stalk route using terrain and wind
Close to 30-40 yard range
Extremely challenging but rewarding

Active Hunting Techniques

Slow still-hunting:

Walk slowly through hog habitat (creek bottoms, thick brush)
Scan continuously with thermal
Stop frequently (hogs often freeze when they sense danger)
Thermal reveals bedded or stationary hogs invisible to naked eye

Calling (underrated technique):

Hog distress calls bring curious hogs
Predator calls work (coyote howls attract hogs)
Use thermal to spot approaching hogs from any direction
Set up in open area with good shooting lanes

The Shot Sequence: From Detection to Release

Here's my step-by-step process for every thermal bow shot.

Step 1: Detection and Identification (Thermal Scan)

Scan environment continuously with thermal
Detect warm signature
Confirm species (hog vs. deer vs. coyote)
Count hogs if multiple (avoid shooting lead sow if trying for multiple harvests)
Assess behavior (feeding, alert, moving?)

Thermal advantage: I can see hogs 200-400 yards away, long before they approach shooting range. I know exactly where they are and where they're heading.

Step 2: Range Confirmation (Laser Rangefinder)

Switch to laser rangefinder
Confirm exact distance to target
Note any obstacles (branches, brush) in arrow flight path
Mentally calculate holdover/aim point

Critical: Don't skip this step. Guessing range with thermal imagery is unreliable.

Step 3: Shot Setup (Body Position and Draw)

Crossbow:

Shoulder weapon smoothly (avoid sudden movement)
Acquire target in thermal reticle
Confirm anatomy (shoulder, vitals visible)
Breathe steadily
Disengage safety

Compound bow:

Confirm hog position via helmet-mounted thermal
Position body for shot
Draw bow smoothly (hogs tolerate slow movement better than sudden jerks)
Anchor consistently
Find aiming point through illuminated sight

Step 4: Final Confirmation (Anatomy and Ethics)

Through thermal scope/sight:

Confirm broadside or quartering-away shot angle
Identify warm chest cavity (vital zone)
Avoid cooler shoulder blade
Ensure no other hogs directly behind target (arrow pass-through consideration)
Confirm ethical shot (range, angle, anatomy)

If anything isn't perfect, DON'T SHOOT. Hogs will be back tomorrow night.

Step 5: The Shot (Release and Follow-Through)

Crossbow:

Center reticle on vital zone
Squeeze trigger smoothly (don't jerk)
Follow through (maintain aim after release)
Watch arrow flight and impact through thermal

Compound bow:

Settle sight pin on vital zone
Trigger release smoothly
Follow through (maintain anchor, back tension)
Track arrow flight

Thermal advantage: You SEE the arrow impact. You WATCH the hog's reaction. You have immediate feedback about shot placement.

Step 6: Post-Shot Assessment (Thermal Tracking)

Immediate observations:

Hog's reaction (jump, run, stagger?)
Direction of travel
Does hog go down within view?
Blood trail visible on thermal? (warm blood shows up distinctly)

Wait time before tracking:

Good hit (double-lung): Wait 20-30 minutes
Marginal hit (single-lung, liver): Wait 45-60 minutes
Poor hit (gut shot): Wait 4-6 hours minimum (or overnight)

Thermal tracking advantage: Blood trail shows up as warm spots on ground for 30-60 minutes after hit. Wounded hog's thermal signature is distinct even in thick cover.

Blood Trailing and Recovery with Thermal

This is where thermal becomes absolutely game-changing.

Why Thermal Excels at Tracking

Traditional blood trailing challenges:

Darkness makes blood hard to see
Flashlights create shadows, glare
Blood on dark soil/vegetation is nearly invisible
Wounded hog may travel into thick cover

Thermal solves everything:

Fresh blood is warmer than ground (shows up distinctly for 30-60 minutes)
Wounded hog shows altered thermal signature (blood loss creates temperature change)
Thermal sees through vegetation (bedded hog is visible in thick brush)
No need for flashlight (stealthier, easier on eyes)

My Thermal Tracking Process

Step 1: Mark the shot location (GPS waypoint or physical marker)

Step 2: Begin tracking after appropriate wait time

Step 3: Scan with thermal at shot location:

Look for blood splatter (warm spots on ground/vegetation)
Confirm direction of travel
Note blood pattern (bright red = lung hit; dark = liver; minimal = poor hit)

Step 4: Follow blood trail thermally:

Blood drops show up as warm signatures
Follow direction hog traveled
Scan ahead for bedded hog (don't jump injured animal prematurely)

Step 5: Locate downed hog:

Thermal shows body even in complete darkness and thick cover
Approach cautiously (confirm hog is dead before touching)
If hog is still alive but down, place finishing shot ethically

Real example: Last season, I hit a 200-lb boar that ran into thick mesquite brush. Traditional trailing would have been nearly impossible in darkness. With thermal, I:

Followed blood trail easily (warm droplets visible for 40 minutes)
Located bedded hog in thick cover at 60 yards
Confirmed he was down but still alive
Placed ethical finishing arrow
Total tracking time: 15 minutes vs. what would have been hours (or lost hog)

Ethical Considerations for Thermal Bow Hunting

With great capability comes great responsibility.

Shot Distance Limits

My maximum distances:

Crossbow: 45 yards absolute maximum (prefer 35 yards)
Compound bow: 35 yards absolute maximum (prefer 25 yards)

Why these limits?

Bow hunting requires precise shot placement
Longer shots increase risk of wounding
Thermal makes long shots POSSIBLE but not ETHICAL
Just because you can see a hog at 100 yards doesn't mean you should shoot

Ethical guideline: If you wouldn't take the shot in daylight, don't take it at night with thermal.

Shot Angle and Anatomy

Take the shot:

Broadside at confirmed range within your limit
Quartering-away with clear vitals
Hog is calm, unaware (better shot placement)

Don't take the shot:

Extreme quartering angles
Hog is alert/jumping (moving target = poor accuracy)
Obstructions in arrow flight path
Any uncertainty about range or anatomy

Multiple Hog Scenarios

Sounders (groups of hogs):

Identify dominant sow (larger, leading group)
If harvesting multiple, shoot subordinate hogs first
Avoid shooting into tightly packed group (risk hitting multiple with one arrow)
Take one shot, let group settle, assess for second opportunity

Ethical approach: Don't shoot more hogs than you can process. Thermal makes 3-5 hog nights possible, but only shoot what you'll utilize.

Wounded Hog Protocol

If you make a bad hit:

Mark the location immediately
Wait longer than you think necessary (4-6 hours minimum for gut shots)
Track diligently with thermal
Make every effort to recover (it's your ethical obligation)
If you lose the blood trail, return next night and scan area with thermal (hogs often bed near where they were hit)

My commitment: I've tracked wounded hogs for 8+ hours using thermal. Every hog I've hit, I've recovered. That's the standard.

Legal and Regulatory Considerations

Before thermal bow hunting hogs, understand the law.

Night Hunting Regulations (Varies by State)

States allowing thermal night hunting for hogs:

Texas: Yes (feral hogs, year-round, no limits)
Oklahoma: Yes (feral hogs, private land with permission)
Florida: Yes (feral hogs, specific regulations)
Georgia: Yes (feral hogs on private land)
Many others: Check your state wildlife agency

States with restrictions or prohibitions:

Some states prohibit ALL night hunting
Some allow night hunting but prohibit electronic optics
Some require special permits

Federal land: Generally prohibits night hunting and thermal optics. Check specific land regulations.

Always verify current regulations with your state wildlife agency before hunting.

Artificial Light vs. Thermal Optics

Important distinction:

Artificial light (spotlights, weapon-mounted lights): Often prohibited for hunting
Thermal optics: Often legal even where artificial light isn't

Why? Thermal doesn't project light, it detects infrared radiation. Legally distinct in many jurisdictions.

But: Some states still prohibit electronic sighting devices. Know your laws.

Property Permission and Access

Landowner permission is essential:

Get written permission for night hunting specifically
Inform landowner you'll be using thermal optics
Respect property boundaries (GPS helps with this at night)
Practice good hunter etiquette (close gates, don't damage property, share harvest if appropriate)

Real-World Hog Hunts: What Actually Happens

Theory is interesting. Let me share actual hunts.

Hunt #1: The Three-Hog Night (Crossbow, Thermal-Mounted)

Setup: East Texas ranch, agricultural field edge, oak grove nearby. Tree stand positioned 18 feet up, overlooking food plot planted with corn.

Time: November, 7:45 PM (full dark)

Thermal advantage: Scanned field continuously. Detected hogs emerging from oak grove 200 yards away at 7:30 PM (before they reached field).

Action:

Three hogs entered field (two 150-lb sows, one 200-lb boar)
Fed across field toward my stand
At 38 yards, I ranged lead sow, confirmed broadside shot
Placed arrow center-chest, double-lung hit
Sow ran 40 yards, went down
Remaining two hogs scattered but returned to feeding after 15 minutes
Second sow approached to 28 yards, perfect broadside
Second arrow, perfect hit, down in 30 yards
Boar remained in field, feeding nervously
Third shot at 33 yards, slightly quartering-away
Perfect hit, down in 50 yards

Result: Three hogs in 90 minutes. Thermal allowed me to take my time, confirm each shot, and capitalize on multiple opportunities without spooking entire group.

Processing note: Don't shoot more than you can process. I spent 6 hours the next day butchering three hogs. Plan accordingly.

Hunt #2: The Thick-Cover Recovery (Compound Bow, Helmet-Mounted Thermal)

Setup: Oklahoma creek bottom, thick brush and willows. Ground-level spot-and-stalk.

Time: December, 9:15 PM

Challenge: Bedded hogs in thick cover, nearly impossible to approach in daylight.

Thermal advantage: Scanned creek bottom from ridge. Identified three bedded hogs in thick willows at 80 yards.

Approach:

Planned stalk using creek bed and wind
Slow movement, frequent thermal checks
Closed to 35 yards
Hogs bedded, unaware

Shot:

Selected medium-sized hog (140 lbs)
Drew bow, confirmed range (34 yards)
Released arrow—slight deflection from small branch I didn't see
Hit was marginal (single-lung, high)

Recovery:

Hog jumped up, ran into even thicker brush
Waited 60 minutes (longer than normal due to marginal hit)
Thermal tracking: found blood trail easily
Located bedded hog at 75 yards in brush so thick I could never have found him without thermal
Stalked to 25 yards, placed finishing arrow
Total tracking: 90 minutes

Lesson: Thermal turned a marginal hit that would likely have been a lost hog into a successful recovery. This is the technology's greatest ethical advantage.

Hunt #3: The Education in Patience (Crossbow, Multiple Hogs)

Setup: Texas Hill Country, sendero (cleared lane through cedar), feeding on acorns.

Time: January, 8:00 PM

Thermal detection: Scanned sendero from truck-mounted shooting platform. Detected sounder of 12 hogs feeding 300 yards down sendero.

Mistake: Got excited, drove closer too fast, spooked entire group.

Recovery:

Waited in position
Scanned with thermal
45 minutes later, hogs returned (they're predictable)
Let them settle, feed comfortably
Waited for perfect shot opportunity

Shot:

Large sow isolated at 32 yards, perfect broadside
Double-lung hit, down in 40 yards
Remaining hogs milled around but didn't spook
20 minutes later, second opportunity on medium boar
28 yard shot, perfect hit, down in 35 yards

Lesson: Thermal allows patience. You can see hogs even when they're not in shooting position. Don't rush. Let opportunities develop naturally.

Common Mistakes and How to Avoid Them

I've made every mistake. Learn from my failures.

Mistake #1: Shooting Too Far

What happened: Saw large boar at 60 yards, perfect broadside. Crossbow shoots flat; I thought "easy shot." Took it.

Result: Arrow hit 4 inches low (misjudged slight uphill angle). Gut shot. Tracked for 8 hours, recovered hog, but it was poor ethical decision.

Lesson: Stick to your limits. Thermal makes long shots tempting. Resist temptation.

Mistake #2: Not Confirming Range

What happened: Thermal makes judging distance hard. Estimated hog at 30 yards, actually 42 yards. Shot went under chest (didn't compensate for trajectory).

Result: Complete miss, hog unharmed but educated.

Lesson: ALWAYS use laser rangefinder. No exceptions.

Mistake #3: Ignoring Wind

What happened: Perfect thermal detection of approaching hogs. Forgot to check wind. Wind shifted, carried my scent to hogs, they spooked at 50 yards before entering range.

Result: Blown opportunity.

Lesson: Thermal doesn't eliminate hunting fundamentals. Wind, scent, noise control still matter.

Mistake #4: Shooting Through Obstructions

What happened: Hog in thick brush, clear thermal signature. Didn't adequately account for small branches between me and hog.

Result: Arrow deflected, high shoulder hit instead of vitals. Long tracking job.

Lesson: Thermal shows the target but doesn't show all obstructions clearly. Verify clear shot path.

Mistake #5: Not Practicing With Thermal

What happened: First night with new thermal scope. Didn't practice during day. Killed hog, but second shot opportunity was awkward because I wasn't comfortable with thermal reticle.

Result: Passed on shot I should have taken.

Lesson: Practice extensively with thermal setup before hunting. Shoot targets at known distances in darkness.

Maintenance and Care for Thermal Bow Equipment

Thermal optics are investments. Protect them.

Battery management:

Carry 2-3 spare batteries per night hunt
Cold weather drains batteries faster (keep spares warm in pocket)
Remove batteries when storing equipment long-term

Lens protection:

Use lens caps when not actively hunting
Don't touch lens with fingers (oils damage coatings)
Clean with proper lens cleaning supplies only

Weatherproofing:

Most thermal scopes are water-resistant, not waterproof
Avoid submersion
Dry immediately if wet
Store in dry environment

Impact protection:

Crossbow recoil can loosen mounts over time
Check mount tightness before each hunt
Use quality mounts (don't cheap out on this)

Zeroing maintenance:

Reconfirm zero every 10-15 shots
Impacts, temperature changes can shift zero
I re-zero at beginning of each season

The Future of Thermal Bow Hunting

Technology is advancing rapidly.

Coming improvements:

Smaller, lighter thermal units (easier mounting on compound bows)
Better resolution at lower cost (640x512 becoming standard)
Longer battery life (8+ hours per charge)
Ballistic calculators integrated into thermal scopes (automatic trajectory compensation)
Bluetooth connectivity (thermal data transmitted to smartphone/display)

Regulatory evolution:

More states legalizing thermal for hog hunting
Possible restrictions on thermal for deer/elk (game animals vs. invasive species)
Evolving definitions of "fair chase"

My prediction: Within 5 years, thermal bow hunting will be mainstream for hog control. Within 10 years, integrated thermal/ballistic bow sights will be common.

Conclusion: Thermal Changed My Hog Hunting Forever

I started this article talking about my first thermal hog hunt—three hogs in four hours.

Five years later, I've harvested 200+ hogs with thermal-equipped bows. My annual harvest went from 8-12 hogs (traditional daytime hunting) to 40-60 hogs (thermal night hunting).

But the numbers aren't the point.

The point is effectiveness, ethics, and enjoyment:

Effectiveness: Thermal turns bow hunting from hoping-the-right-hog-shows-up to actively-hunting-detected-targets. Your success rate increases dramatically.

Ethics: Thermal improves shot placement confidence and dramatically improves recovery rates. Wounded hogs that would be lost in traditional hunting are recovered with thermal tracking.

Enjoyment: Night hunting with thermal is thrilling in ways daylight hunting isn't. You're hunting when hogs are most active, most predictable, and most vulnerable. Every hunt is productive.

My recommendation: If you bow hunt hogs, invest in thermal optics. Start with mid-range equipment, learn the techniques, and watch your success rate transform.

Thermal isn't cheating. It's not unfair advantage. It's a tool that makes bow hunting—already difficult and skill-intensive—more effective and more ethical for invasive species control.

The hogs are out there right now, feeding in darkness. With thermal, you can see them.

Time to hunt.
