Telescopic shaft for metal detectors, light-weight and easy to transport. Made from 100% carbon fibres, light and strong. Very compact when collapsed. Could be used with PI detectors, XP Déus (there is no control unit holder!) or self-made machines. It is not possible to mount a GM control box on this shaft outside of the GM factory. Mounting of a GM control box requires opening of the detector and this voids the warranty. You can order a compatible Golden Mask detector with this shaft instead of the regular S-stem. The maximum weight of the coil attached to the shaft is 0.750 kg! WARNINGS: Be sure to have at least 5 cm (2") one section into another while you extend the shaft and tighten the fixing screws - this insures strength and long life of your shaft!
