OneLeaf MARS Mini 640×512 • 60Hz – 25mm Thermal Imaging Scope (Pistol/Rifle)

25mm Lens = 1.6× Base Magnification | Extended-Range Version

The OneLeaf MARS Mini 25mm packs an impressive 640×512 @ 12μm thermal sensor, ultra-sensitive <20mK NETD and fast 60Hz refresh rate into an incredibly compact thermal optic weighing just 195 grams.

The 25mm F/1.0 lens provides 1.6× base magnification, giving you more reach and target detail than the wider-field 19mm version while retaining the compact size that makes the MARS Mini unique.

Designed for both rifle and pistol use, it also features a built-in 1500m laser rangefinder, ballistic calculator, 720×720 touchscreen, shutterless thermal imaging, video recording and Picture-in-Picture mode.

For NZ hunters wanting an extremely compact thermal scope with a little more magnification and reach, the 25mm is the pick of the two MARS Mini lens options.

Why Choose the 25mm?

The 25mm MARS Mini is the longer-range version of the MARS Mini.

Its 1.6× base magnification provides greater target detail than the 19mm version, making it particularly well suited to open-country pest control and situations where targets are likely to be encountered at greater distances.

Despite the larger lens, the complete unit weighs only 195g, making it considerably smaller and lighter than most conventional 640-resolution thermal riflescopes.

For hunters who prioritise the widest possible field of view and true 1× viewing for closer-range shooting and scanning, see our separate MARS Mini 19mm listing.
