Garmin’s tactix Delta is the latest in its line of rugged smartwatches built to military standards. A big 1.4-inch display, a power manager feature, gives you battery life predictions based on which settings you turn on and off.

New features include stealth mode, a kill switch that can be set to erase all device memory. They individually appeared in the instinct tactical edition and marq commander watches respectively.

New privacy features include jumpmaster mode, dual-position GPS and jumpmaster mode. Dual-Position GPS can display two sets of coordinate systems on a single screen.

Garmin tactix delta can store up to 2,000 songs and supports Garmin pay. Garmin says you’ll get 21 days of battery life when the device is in smartwatch mode, or 80 days in battery saver watch mode mode.
