With the SHOTMAXX, it’s worn on your wrist as a watch keeping it off your belt or pockets but still readily accessible. The mic is sensitive enough to pick up airsoft, but I have not tried this feature.

Looks like a great timer and being wrist-worn is a genius idea.  Both sound and accelerometer activated is just pure french vanilla icing on top besides all the other high-tech goodies that are in the small package. The $149 tag is not bad at all compared to other timers.

My only question: How will it stand to water? Sometimes, at the range, it rains. Then again none of the other timers do good in flood conditions.
