Inim, telescoping fiber optic tube, 2.5m maximum tube length, working height up to 4m (2 extendable pieces)

All Solo sticks are made of reinforced fiberglass, the poles are lightweight, so work at height is not a problem. The sticks do not sway as for example, if a detector at a height has to be rotated out of its base. They are very robust and made of a non-conductive material.
