I have a DIV01 and a DIV03 and have been extremely satisfied with them! I am very impressed with the selection of dive lights and look forward to getting a DIV10 or DIV20 for this season (cold New England dark lakes). I would like to see something like the DIV20 with the ability to mount both a wide beam angle video head AND a tight beam angle spot at the same time running off the same canister. These heads being able to be controlled independently would be amazing!
