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 analog 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.

Note: Galaxy Extreme lens is not user replaceable. Only available in black.
