Overview
Hiking, surfing and working a job site are the uses KOSPET built the Tank around, with a stainless steel structure and an AMOLED screen under Gorilla Glass. A built-in flashlight, dual band satellite tracking and walkie talkie calls work alongside heart rate, blood oxygen and sleep monitoring.
Choose the KOSPET Tank for field features built into the case: a flashlight, phone free push to talk with other wearers and dual band satellite tracking. Health reports live in the Apexmove app, and the battery figures vary between the bullets and the spec table.
Who it's for
Field crews, campers and group hikers who work in rain, dust and the dark get the most from the rugged case and built-in light. People who only want step counts and notifications at a desk will be carrying ruggedness they never use.
Pros and cons
- Built-in flashlight with adjustable levels
- Push to talk without cellular service
- Dual band satellite positioning
- High water and dust resistance
- Battery life figures conflict in the listing
- Walkie-talkie range varies with conditions
- Little onboard memory
- Detailed health reports need the companion app
Performance notes
Position accuracy comes from the dual band receiver reading several satellite systems at once. Runtime falls as you lean on GPS and the flashlight, which each carry their own shorter rated figures. Heart rate, blood oxygen and sleep readings come from the optical sensor array and feed the Apexmove app.
