What stands out is very positive that can be with the telescopic pole pretty quiet, less shaky, take pictures. When you hold the telescopic pole a little further forward you can see the bar even further stabilize the forearm, which is useful especially in rough seas or flow!
An ascent and on the surface simply use the carabiner and the camera together with telescopic pole mount in order to have both hands free.
Since the bar has 3 telescopable aluminum segments it takes a while until all the water from the interstices again is out. When the rod but several times and extends the remaining water is simply pushed through the plastic covers.
So far I have found no problems with the saltwater. The product is of high quality and very well made. I can every diver of a GoPro has only recommend!
