Review on Polyform A-Series Marine Buoy by Fred Vazquez

Used the A2 as a dive buoy and it works great. To make a depth-adjustable setup, I rigged up a 5/8" utility rope with a prusik loop, as seen in the photo. This made my dives so much easier, as I could tighten the line on the fly and have a fairly rigid line to ascend and descend with.I was initially unsure if I should go with the A2 or the A3. For shore dives with placid lake water, the A2 was perfect and I didn't need anything bigger. A3 could be a better option if you're diving off of a boat.
