The Pocket Box connects to your three-pronged body wire, just like a wired system. Slip it into your trouser pocket and touch on your weapon. When the Pocket Box is snug against your body, the EnPointe Wireless System leverages unique, patented technology to wirelessly register hits. The Pocket Box is made of durable aluminium and fibreglass, and is compatible with any Relay Box – just touch on with your opponent and you’re ready to fence. The Pocket Box uses two AAA batteries and runs for up to 90 hours of continuous fencing on a single set, or about three months of regular club use.
