Today, XP is once more pushing the limits by creating, the first wireless, multi-frequency metal detector with unique features and performance. Once the coil, remote control, headphones, and optional pinpointer are paired, they communicate with each other wirelessly and without latency using the XP patented radio protocol system. This means that the target signals generated by the search coil are quickly transmitted to the headphones without any delay, giving the DEUS II unparalleled speed and accuracy. The DEUS 2 performs extremely well in all terrain and conditions, both on land and at sea, thanks to FMF ;(Fast Multi Frequency) technology. Waterproof to 20 meters.
