Guides
Each guide is a filter over the same catalog, so nothing here can claim a unit we have not recorded. Every list says which figure it is ordered by — usually one of our range estimates, never the box claim, and never an opinion.
640 thermal scopes under ~$3,000
A 640 sensor used to mean five figures. It does not any more. These are the 640-class riflescopes that list under roughly $3,000, ordered by the detection range we compute from the lens and pixel pitch — the box figure is shown beside it so you can see how far apart the two yardsticks are. Prices are a snapshot, not a quote.

Handheld thermals for coyote hunting
Calling coyotes is a scanning game: you glass for an approaching heat source, then you need to know it is a coyote and not the neighbour's dog before you reach for the rifle. That second job is recognition, not detection, so this list is ordered by our recognition estimate — eight pixels across a 0.5 m target. Weight matters because the unit lives in one hand for an hour at a time.

The lightest thermal clip-ons
A clip-on mounts in front of your day scope, so its weight hangs at the far end of the rail where it does the most damage to balance. These are the clip-ons in the catalog ordered by the maker's published weight, lightest first. Weight is the manufacturer's figure for the unit alone, without a mount unless stated.
10 units · Sorted by weight, lightest first.
Entry-level 384 thermal scopes
A 384 core is where thermal starts being affordable, and for hog and coyote work inside 200 yards it is more than enough. These are the sub-640 riflescopes in the catalog, ordered by approximate price so you can see exactly what each step up buys in lens and range. The estimate column is ours; the claim column is the box.
11 units · Sorted by approximate price, lowest first.
Thermals with the longest battery life
Cold is the enemy of every lithium cell, and a thermal that dies at 2 a.m. in January is the one you will remember. These are the units whose makers publish eight hours or more of run time. The figure is the manufacturer's, usually at room temperature with Wi-Fi off — expect less in the cold, and weight the removable-pack units accordingly because a spare in your pocket doubles the number.
23 units · Sorted by published run time, longest first.
Thermal scopes with a built-in rangefinder
Judging distance through a thermal is hard — there is no ground texture, no fence posts, nothing to scale against — which is why a built-in laser rangefinder is the upgrade most people wish they had bought first. These are the riflescopes in the catalog that have one. Ordered by our detection estimate, because a rangefinder that outranges the sensor is not much use.

12 µm handheld thermals
A 12 µm pixel is half the area of a 17 µm one, so a 12 µm core reaches the same field of view with a shorter, lighter germanium lens. That is why the current generation of handhelds fits in a jacket pocket. These are the 12 µm handhelds in the catalog, ordered by our detection estimate.
16 units · Sorted by estimated detection range, longest first.
60 Hz thermal scopes
Most thermal cores run at 50 Hz, a leftover of the European video standard. A 60 Hz core redraws the scene 20 % more often, which is the difference between tracking a running hog cleanly and watching it smear. These are the riflescopes in the catalog whose makers publish 60 Hz.
