Hollis H-160 Scooter (DPV)

William:

I am having a rough time trying to compare DPVs. In particular, Id like to know the pounds of thrust and run time comparisons between the high end SEADOOs and the Hollis or Farralon higher end units. The cost is so incredibly different that I am sure the difference must be something more than longevity since one could buy new SEA DOOs with fresh batteries every year for 5 or six years and throw away the old ones and still come out ahead compared to high end Farralon. I did use a small Farralon a few years back, but, the difference I thought was more one of balance and direction.To give the top speed doesnt help without knowing torque or foot pounds of thrust, and perhaps balance, and pull against the flow resistance of a bulky gear set up. Without a connecting cord the force could pull the unit out of ones hands or pull off ones mask etc, which is why they tell us its pressure safe to almost 600 feet(I guess). I bought two DPVs from you about a year ago, and they do help cover alot more territory SEADOO Explorers. They do have a little trouble pulling me from the surface even when neutrally bouyant. The question is , "Is it possible to get data on these units which compare apples to apples?" I have checked specs on the manufacturers websites and tried checking online with DPV clubs no one seems to know.. Thank You for any help you can give. Sincerely, Bill Nuesse MD
