The automatic shot detection feature of Suunto Traverse Alpha was developed specifically for hunting. It works best with hunting rifles and shotguns. It is not intended for handguns or other firearms.
The shot detection algorithm uses a complex formula that takes into account motion patterns from both wrist and gun recoil movement measured by the accelerometer in the watch.
The automatic shot detection works with the watch on either wrist. However, for some users, the shot detection rate is more accurate when the watch is on the trigger hand.
We recommend that the watch strap is secured tightly on the wrist to eliminate disturbance from other sources of movement.
Results may vary depending on many factors, including firearm type, grip type, and accessories such as a support or suppressor. In some cases, a shot may be detected based on movement that is similar to a recoil, even though no shot is actually fired.
