This timer was made specially for solo training in the sport of practical shooting.
The device works just like a regular IPSC timer and also has the ability to enter the score into it after the shooting and it will automatically calculate the score factor.

This has been tested on a shooting range and works great.

It has been made using Makerbot Replicator 3D Printer for the chassis and Probotix Fireball V90 CNC for routing the PCBs.
The electronics is based on the Arduino UNO technology.
