Had to choose between the OMS IQ system and the Dive Rite harness. Called Dive Rite to ask about specs on their systems...got a guy named Dyson on the phone who spoke with me for 20 minutes about the Dive Rite systems. I then called OMS and was told that they wont talk to customers at all! So my decision was made, buy Dive Rite. The problem was that my LDS had a blowout special on one last OMS rig and no Dive Rite products in stock...I had no choice...I am now the owner of an OMS IQ system. Having said that, with more time and money I will buy Dive Rite. Thanks Dyson for all the time you spent with me. In the future, I'll be back. Your company is the best.
