zmanzimp:
what are your opinions of OMS products, namely their bcs and harness systems? I am looking at the oms Iq harness and am wondering if anyone has had good/bad experiences with them. how is oms compared to dui/dive-rite/halcyon/etc.? thanks, zach
OMS makes good quality equipment that ranges from recreational to technical. The IQ harness is more a crossover from the tech to rec category. It takes some of the principles from a technical rig and makes them more diver friendly for the recreational diver.
I dive an OMS SS bp with a variety of their wings. I don't buy their bungeed wings, but I do like the versions without bungees. I opt for their shorter inflator hose as well. There aren't any huge differences in backplates from one company to another. A basic harness is just webbing with SS d-rings. Again, no big difference here. Dive Rite and OMS offer variations of the basic harness that incorporate quick disconnects to make the rig easier to get in and out of while wearing a drysuit with arm dumps. They also make it easy to switch between different thickness wet and drysuit options since you can cinch the shoulders down. These delrin clips are considered failure points, but offer convenience for the minor tradeoff.
The IQ and TransPac offer more comfort over a bp, but you loose some stability compared to a bp. The comfort is somewhat debateble once you dive both, since most feel a bp is very comfortable without the padding. These rigs are not set up for diving doubles and would not offer the neccessary lateral support.
You have to decide if you are DIR, not DIR, or take some of the DIR concepts and work them into your rig. I opt for the latter of these three for now, but I am gradually working toward the first as my diving experience and goals grow.
My rig:
OMS SS Backplate
OMS Comfort Harness
OMS non bungee wings (single tank and dual tank)
Halcyon trim weight pockets
This setup works for me and I'm very happy with the quality. My max dives are to 185' with short wreck penetrations and short deco obligations.
I'm not trying to persuade you either way, just give you my two cents.
