The best thermal scopes under $1,000

What under $1,000 buys you

Hogs don't wait for you to save up. If they're emptying the feeder this month, a budget thermal can put you over it tonight, as long as you buy for the distance you'll actually shoot. Under $1,000, almost every thermal riflescope uses a 256x192 sensor behind a 15 to 25 mm lens. One puts a 384 sensor behind a 35 mm lens. That's the whole tier in two sentences, and it decides everything else.

What matters for seeing a hog is how many sensor pixels land on it. That depends on pixel pitch and lens focal length, both of which most makers in this tier publish. The formula, and why it works, is laid out on our main thermal scope ranking for hogs. The short version: inches covered by one pixel = distance in yards × 0.036 × pitch in µm ÷ lens in mm. Divide the hog's length by that.

Read the table in both directions. The short-lens 256s show the widest slice of ground, which is exactly what you want when a sounder pours in around a feeder at 40 yards. The longer lenses put more pixels on each hog but show less ground, so a moving animal leaves the view faster. There's no scope in this tier that does both well. Pick the one that fits your shots.

Is a 256 sensor enough for hogs?

At feeder distance, yes, by the numbers. The ThOR 6 Mini puts about 42 pixels across a big hog at 50 yards, and the Rattler V2 about 53. The 35 mm GRL335 puts that many on a hog at roughly 90 to 115 yards. So a short-lens 256 at a close feeder shows a hog about as well as the 384 does at a small field's width.

Where a 256 runs out is distance. At 150 yards the ThOR 6 Mini is down to about 14 pixels across that same hog, and our skip notes on both scopes say the same: the 15 mm and 19 mm lenses are close-range tools. If your shots are past about 150 yards, the GRL335 in this tier or a scope from our under-$2,000 thermal picks is the better buy. For the full breakdown by sensor size, see 256 vs 384 vs 640 thermal.

Pixels aren't the only measure. Sensitivity (NETD, where lower is better) affects how cleanly a hog separates from warm ground. This tier runs from ≤20 mK (ThOR 6 Mini) to <35 mK (Rattler V2, GRS225). And digital zoom doesn't add pixels; it enlarges the ones the lens already put on the animal.

How we picked

We took every thermal riflescope in our registry that Amazon listed in the under-$500 or $500 to $1,000 tiers when we checked on September 19, 2026, and read each maker's spec page and warranty terms. Each is scored on our published thermal rubric: sensor and lens for identifying a hog (30%), usability at night (20%), battery and power (15%), durability (15%), warranty and support (10%) and value within its tier (10%). Detection-range figures are the maker's claim.

We haven't tested these units; scores come from published specs and the rubric on our How We Choose page. Two more scopes in this tier didn't make the ranking: ATN's older ThOR LTV 256, whose page skips NETD, battery life and IP rating, and a 19 mm DNT Optics Hydra whose Amazon listing publishes little beyond sensor and lens.

The picks side by side

The picks in context

1. GOYOJO GRL335

The one budget scope built for reach. Its 384x288, 12 µm sensor behind a 35 mm lens puts about 49 pixels across a big hog at 100 yards, double the ThOR 6 Mini. It adds <25 mK NETD, a five-year warranty, a published 1000 g recoil rating, 64 GB of storage and a thermal one-shot zero. It loses points on usability: a 4x base with GOYOJO's listed 6.5° x 4.5° view is narrow when hogs are close and moving. It's IP65, splash resistant rather than the IP67 the ThOR 6 Mini, Rattler V2 and GRS225 list. If most of your shots are inside 75 yards at a feeder, one of the next two scopes suits you better.

2. ATN ThOR 6 Mini 256 2-16x

The best-built budget scope on paper and our pick for close feeder work. ATN publishes IP67, a 6000 J recoil rating, a -22°F to 131°F operating range and a five-year warranty, and the ≤20 mK NETD is the most sensitive in the tier. The 15 mm lens gives an 11.7° view, about 61 feet wide at 100 yards, so a sounder milling around a feeder stays in the picture. The trade-offs are reach (about 21 pixels across a big hog at 100 yards), a small 800x600 display, and about 4 hours per 18650, with two in the box and USB-C power for more.

3. AGM Rattler V2 19-256

The easiest to live with through a long night. AGM rates it up to 11.5 hours per battery and puts a second NE-4400 in the box, the best runtime in the tier. It adds a 1024x768 OLED, IP67, 16 GB with shot-activated recording and AGM's five-year warranty for US buyers. The 19 mm lens sits between the ThOR 6 Mini and the 25 mm scopes, and AGM publishes a 9.3° view (49 x 36 ft at 100 yards). NETD is <35 mK, and AGM doesn't publish a recoil rating for this model.

4. RIX Storm S2 (256x192, 25 mm)

More reach than the 15 to 19 mm scopes from a 25 mm lens with a 3.5x base, plus <25 mK NETD, a 1024x768 OLED, five zero profiles and a quick-detach Picatinny mount in the box. RIX publishes no IP rating, recoil rating or pixel pitch for the S2, and the warranty is three years. Buy it for a mid-distance field in dry country; skip it if you hunt in heavy rain.

5. GOYOJO GRS225

The sharpest display among the budget 256s (a 1440x1080 OLED) with a 25 mm lens, IP67 and a published 800 g recoil rating. Two things pull it down: the main 18650 is built in, so you can't swap a fresh cell mid-hunt (a CR123 backup isn't included), and the warranty is one year, the shortest here. GOYOJO sells a GRS225RF variant with a rangefinder.

6. Athlon Cronus ATS PRO 25P-250

A 25 mm, 12 µm 256 with a 3.6x starting magnification, a 10+ hour battery claim with USB-C power, recoil-triggered Auto-Shot recording and a ballistics calculator in Athlon's app. It ranks last because Athlon's product page leaves out the refresh rate, IP rating, recoil rating and warranty length. No spec, no score: those gaps cost it points on durability and support.

Thermal scope under $500: what actually exists

Plenty of people search for a thermal scope under $500, so here's the plain answer. When we checked Amazon on September 19, 2026, none of the thermal riflescopes we could verify against a maker's spec page sat in the under-$500 tier. The cheapest in our registry landed in the $500 to $1,000 tier. If a listing claims otherwise, check that it publishes a sensor resolution, pixel pitch, lens focal length and warranty before you trust it.

What does exist under $500 is useful, just different:

• Handheld thermal monoculars. The AGM Taipan V2 10-256, ATN BlazeSeeker 6 and TOPDON TS004 were all in the under-$500 tier. They scan for heat; they don't mount on a rifle. Many landowners start here and add a scope later. See our best thermal monocular for hunting.
• Digital night vision scopes. The PARD NV008SP2-LRF, our top night vision pick, was in the under-$500 tier, along with Triton, Sightmark and CyberDyne models. They need an infrared illuminator in the dark. See our best night vision scope for hog hunting.
• A light over the feeder. Colored hunting lights and feeder lights cost far less than thermal and work at feeder distance. Our guide to hunting hogs at night without thermal covers that route.

The clip-on option in this tier

If you already own a good day scope, a thermal clip-on sits in front of it and keeps your reticle. Several were in the $500 to $1,000 tier when we checked: the ATN TICO 6 256, the DNT Optics Hydra HS225, the AGM Rattler-C V2 and the TKC Sirius. The TICO 6 and Hydra also work as handheld scanners. They're ranked on our best clip-on thermal page, which explains how makers say their clip-ons mount and what they say about zero.

What to look for in a budget thermal scope

1. A lens that fits your longest honest shot. 15 to 19 mm for a feeder inside about 75 yards; 25 mm for a small field; 35 mm if you regularly shoot past 100 yards. The table above shows the pixel trade.
2. A battery you can swap in the dark. The Rattler V2 and ThOR 6 Mini both include a spare. The GRS225's main cell is built in. On a budget scope, runtime is often the first thing that ends a hunt.
3. Published waterproof and recoil ratings. IP67 plus a recoil figure is the baseline to want. In this tier, the ThOR 6 Mini publishes both; RIX publishes neither for the Storm S2; Athlon's page lists neither.
4. A warranty that outlasts the novelty. Five years from ATN, AGM (US purchases) and GOYOJO on the GRL335; three from RIX on the S2; one from GOYOJO on the GRS225; not stated on Athlon's page.
5. Zeroing that's quick at dusk. One-shot zero or zeroing freeze (GOYOJO and ATN list them) and multiple zero profiles (RIX lists five) save ammunition and daylight. Our guide on zeroing a thermal scope walks through it.
6. A mount in the box. Most budget scopes ship with a Picatinny mount (AGM ADM, RIX QD, ATN rail mount). Check your rifle's rail before you buy.

Budget tiers: where under $1,000 fits

If you can wait and stretch, the step from this tier to the next buys the most detail per dollar in thermal: roughly double the pixels on a hog at 100 yards. Our guide to what a thermal scope costs lays out each tier, and the thermal and night vision hub has every option in one place.

Getting the most from a budget thermal

A budget scope has less detail to spare, so the setup around it does more of the work.

• Know the distance before dark. Pace or range the feeder, the gap in the brush and the far fence line in daylight. With 20-odd pixels on a hog at 100 yards, you don't want to be guessing range as well.
• Zero at the distance you'll shoot. If every shot is at a 60-yard feeder, zero there. Save a second profile if the scope offers one and you also shoot the field edge.
• Scan with something else if you can. A handheld monocular lets you look over the whole area without sweeping a rifle across animals you haven't identified. See thermal monocular vs thermal scope for how scanning and shooting split between the two.
• Shoot from a rest. A steady rest matters more with a 1 lb scope on the rifle and fewer pixels to aim with. Our shooting sticks and tripods page ranks the options.
• Carry the spare battery, charged. The ThOR 6 Mini's rating is about 4 hours per cell and the GRL335's 6 to 8 hours. A feeder that gets hit at 3 a.m. needs a scope that's still on.
• Use the recording. All six picks list shot- or recoil-activated recording. Reviewing the clip tells you where the shot went when you can't see the hit in the dark.

Budget thermal mistakes

• Shopping by detection range. Budget scopes here claim 950 yards to more than 2,600 m. Those are the makers' claims for spotting a heat source, not identifying a hog.
• Judging by the zoom number. "2-16x" or "2.5-20x" is mostly digital zoom. Compare lens size and base magnification.
• Buying reach for a close feeder. A narrow scope at 40 yards can lose a moving hog. The GRL335 is built for 120 yards and is hard work at 40.
• Ignoring the one-year warranty. A thermal is electronics on a recoiling rifle. The warranty is part of the price.
• Expecting one scope to fix the problem. Shooting takes out a few hogs at a time. Pair the scope with trapping; our guide on getting rid of feral hogs shows the whole plan.
