The xp Deus 2 remote bumper, key ring, and lanyard is a convenient accessory for metal detector enthusiasts. This product allows users to easily operate the remote control for their xp Deus 2 detector and also provides a secure way to carry the remote around. The key ring and lanyard make it accessible on the go, The bumper will help stop you knocking the remote off by giving the bracket more stability and the lanyard goes over the shaft before you fit the coil ,so if the remote is knocked off the lanyard will stop you losing it , this is based on my experience losing my remote twice on separate digs
