Is the Nighthunter H35 worth it?

It suits buyers who want a rugged, simple thermal monocular and value Steiner's build quality. Compare its price against 35 mm rivals before deciding, since its narrow field of view and 3 lb weight are real trade-offs.

How far can it detect heat?

Steiner does not publish a detection range in the specs given. The 35 mm lens and 1x magnification put it in the mid-range for handheld thermal, so expect to identify large heat sources at a few hundred meters and recognize animals closer in.

Does it have a wide field of view?

No. It covers 12.5 x 9.4 m at 100 meters, which is narrow for scanning open ground. It is better for looking at a specific area than for sweeping a wide landscape.

Is it good for one-handed use?

It weighs 3 lb and measures about 9.8 x 11.3 x 5.2 in, so most users will want two hands or a tripod. It is not a pocket device.
