White Hot is where most shooters start — and often where they stay. In this mode, the hottest objects appear bright white against a darker background, with the coldest areas rendering in deep black. The result is a clean, intuitive image that mirrors how we naturally perceive light-to-dark contrast.

Best For:

▶  Cold-weather hunts where animals thermally separate from cool ground

▶  Open terrain — fields, food plots, clear cut lanes

▶  Long glassing sessions where eye fatigue is a concern

▶  Beginners learning to read thermal imagery

▶  Snow or frost conditions where backgrounds are uniformly cold

Black Hot is the inverse of White Hot — warm objects appear dark against a lighter background. While that sounds counterintuitive, it's a game-changer when conditions are working against you. When brush, terrain, and animals are all holding similar heat, it's edges and body shape — not brightness — that let you positively ID a target.

Best For:

▶  Warm summer nights when vegetation is still radiating heat

▶  Hunting near thick brush, tree lines, or dense cover

▶  Close-range hog or predator work where target shape matters

▶  Law enforcement and tactical use — silhouettes read naturally

▶  Experienced thermal users who prefer shape over brightness

Red Hot paints the most intense heat sources in vivid red while cooler areas shift toward white or gray tones. The Nexus Mini's 256x192 sensor renders body heat as unmistakable red against a neutral field — your eye is drawn to the heat signature before your brain consciously registers it. This is about speed.

Best For:

▶  Scanning large open areas rapidly for game detection

▶  Hog hunting from elevated positions over big fields

▶  Locating wounded game that has bedded down

▶  Quick-scan reconnaissance before engaging

▶  Any scenario where detection speed outweighs detail

Fusion distributes heat across a full color spectrum — assigning different colors to small increments of temperature variation. Where White Hot and Black Hot show a binary warm/cool contrast, Fusion shows a gradient. That gradient reveals subtle temperature differences that single-color modes simply can't render.

Best For:

▶  Warm, humid nights when the environment is thermally 'flat'

▶  Desert or Southern climates in summer months

▶  Distinguishing live animals from recently vacated beds

▶  Identifying warm mechanicals, engines, or electronics in tactical use

▶  Situations where everything seems to blend together in other modes

Great for the size

"This thermal sight is amazingly clear for it's small size. I can't wait to try it at night."

★★★★☆

The thermal itself is awesome

"The thermal itself is awesome — pic quality and ease of use and detection. I am a little disappointed reading the manual learning it is not moisture resistant like my other thermals."

— Larry S.

Amazing miniaturized thermal

"This miniaturized thermal is amazing and a great off-set optic. Highly recommend — quality is top notch and the screen is bright and vibrant. Touch controls are responsive and this is exactly what I was hoping it would be."
