Alti-2 Altimaster Galaxy EXTREME Analogue Altimeter


Alti-2 Europe Logo

All the great features of our Altimaster Galaxy, and it’s waterproof too!

The Altimaster Galaxy Extreme was originally developed for pond swoopers who prefer a mechanical mechanism and an analogue dial face.

It has since gained popularity among military end-users because of its familiarity with their current (non-waterproof) devices and smaller overall profile.

This model is based on Galaxy but has a specially designed frame and lens to allow waterproofing.

The Extreme is only available in black. Choose any face option: glow, white, metric, or feet.

Note: Galaxy Extreme lens is not user replaceable.
