Best Thermal for Rabbits & Small Game (Why FOV Beats Reach)

Rabbits and other small game are the perfect example of why "more range" isn't always the right answer in thermal. Small, fast, close targets reward a completely different setup to long-range work — and getting it right makes for some of the most fun thermal hunting going. Here's what matters.

Quick answer

For rabbits and small game, prioritise a wide field of view and a fast refresh rate over reach. A shorter 25–35mm lens with a 640 sensor gives you the wide, low-magnification view that keeps fast little targets in frame, and a 50Hz refresh stops them smearing as they bolt. This is the one scenario where field of view clearly beats long-range reach — don't overspend on a long lens you don't need.

Why field of view beats reach here

Rabbits are small, they're close, and they move in quick, unpredictable bursts. That changes the priorities entirely:

• A wide view keeps them in frame. At close range a narrow, highly magnified picture loses a bolting rabbit instantly. A shorter lens and a larger sensor give you the wide, low-base-magnification view you need to track them.
• Refresh rate matters. A 50Hz refresh keeps fast movement smooth; a slower refresh smears a sprinting rabbit.
• Reach is almost irrelevant. You're shooting close, so a long 50–60mm lens just narrows your view and costs more for no benefit. This is the opposite of a long-range deer setup.

Building a small-game setup

The scope or monocular

A 25–35mm-class thermal with a 640 sensor gives the widest, most trackable picture for close work. The 640's wider field of view at a given lens is a real advantage on small fast targets (see our 384 vs 640 guide). A 384 still works and saves money; just keep the lens short for a wide view.

Low base magnification

You want a low base magnification so the picture stays wide. Resist the urge to use digital zoom to "get closer" — it just degrades the image and narrows your view, exactly what you don't want on a darting rabbit (see our digital zoom guide).

A realistic word

Small targets need clear identification before the shot just as much as large ones — make sure you can confirm what you're aiming at. And check your state's regulations: thermal is legal to own across Australia, but some states restrict its use for hunting, particularly on public land.

FAQ

What's the best thermal for rabbits?

A short-lens (25–35mm) thermal with a 640 sensor and a fast refresh — the wide field of view and smooth movement tracking suit small, fast, close targets far better than a long-range scope.

Do I need a long-range thermal for small game?

No — it's the opposite. A long lens narrows your view for no benefit at close range. Prioritise a wide field of view and low base magnification.

Is a 640 sensor worth it for rabbits?

Yes — the wider field of view at a given lens helps you keep fast little targets in frame. A 384 works too if budget is tight; just keep the lens short.

Should I use digital zoom to get closer to a rabbit?

No — digital zoom degrades the image and narrows your view, which is the worst combination for a moving rabbit. Stay at base magnification.
