12x magnification with 42mm objectives and BAK4 roof prisms delivers a wide field of view. Sealed rubber armour and included accessories support outdoor use and simple digiscoping.


Bright, detailed views - thanks to BAK4 prisms and fully multi-coated lenses

BAK4 roof prisms improve light transmission and reduce internal scatter, while fully multi-coated (FMC) optics increase contrast and colour fidelity. A 42mm objective captures a useful amount of light for daylight and twilight use.

Clearer images with less colour fringing when scanning landscapes or watching birds. Daytime and low-twilight scenes remain easier to make out than with untreated optics.

Comfortable, customisable focus - with dual focus knob and diopter adjustment

A central focus knob works with a separate diopter ring to fine-tune focus for unequal eye sight, while twist-up eyecups allow quick eye relief adjustment for spectacle wearers.

Sharp focus across both eyes, fast target acquisition while moving, and comfortable viewing for spectacles users without compromising eye relief.

Easy digiscoping and stable long sessions - thanks to smartphone adapter and tripod mount compatibility

Handheld use pairs with a supplied smartphone adapter that fits phones 5.7cm to 8.6cm wide, and a tripod mount accepts standard supports for steady, extended observation. Rubber armouring offers a secure grip and shock absorption.

Quickly capture photos through the optics using a phone or lock onto a tripod for lengthy watches, reducing hand fatigue and improving image stability.
