If you are having trouble getting the pole tightened:
Have you tried turning the yellow part of the pole in opposite directions for several rotations until it tightens? It tightens like a hiking pole or painter’s pole. When held upright, the top (thicker) section of the pole needs to be turned clockwise, like the “righty-tighty, lefty-loosey” saying.
Sometimes Aquablade users turn the blue part in the middle of the pole rather than just turning the yellow poles. The blue section does not have a role in tightening.
Poles can be like a ballpoint pen sometimes, so the internal mechanism might need a slight adjustment. Hold the pole upright (with the threaded end upwards) and just tap the pole on the floor a couple of times.
One other tip is when the pole is fully extended, there is not enough threading to tighten the unit. Simply pull the pole all the way out and re-insert by about 1/2 inch to ensure the threading is exposed inside the pole.
