Several months ago, I sent an email inquiring whether Hollis had any other available trim weights for the H-160 DPV. I was sent a reply (that for the life of me, I can't find, now) that There was not & that Hollis would look into whether different trim weights could be developed, but have heard nothing new. Here's where this is coming from....
1. In fresh water, when not in operation, the H-160 is very negatively buoyant with the 2 factory supplied trim weights (.8 lbs each). When in motion, the DPV "planes out" neutral (for lack of a better term). I tried the DPV without any trim weights & it was very negative in the rear & very positive in the nose (almost pointing straight up). I tried it with 1 trim weight,... it was still too rear heavy & nose light & also listed to the side of the remaining weight, so neither of those options would work. There is also a warning in the owner's manual to not use any other weighting systems on the DPV, for fear it may damage the other parts of the DPV. Don't get me wrong,... I absolutely love the balance the factory supplied trim weights give. It makes the scooter very easy to handle. In what conditions are the factory trim weights made for? Saltwater, maybe? Or just to balance the DPV?
2.In the future, I am wanting to use the scooter for freshwater cave diving, but need the scooter to be just barely negatively buoyant,... almost neutral would be optimum.
Has there been any new developments in other trim weights for the scooter, as was mentioned in the reply I got? I am just wanting to make the most out of the DPV & not have to worry about damaging the fragile environment of the underwater caves. Thanks!
