This page covers the various topics needed to maintain your freETarget

Setting the Trip Point

freETarget works by listening for the sound of the projectile passing the microphones. In a perfect world, you want to set this as low as possible, but in the real world the sound of other shots might set it off. This document lets you adjust the trip point to your environment.
