Hello everyone, Im pretty new to this but willing to learn, Im looking for some advice on equipment, initially a good set of wings. My first thought was the Dive-rite superwings but a couple of guys at my club are using OMS wings and swear by them ( Im based in the UK and Im interested in wreck diving ). The concept of the bungee cords seems good to me, the guys who dive with them think they are great and have had no problems but I get the feeling from you guys that they are not such a good thing???????? Im reviewing my set up and approach to equipment and believe that you should be primarily self sufficient, to be able to deal with all emergencies independantly and that your buddy is effectively a bonus. I base this on the fact that if equipment is not 100% predictable, your buddy 50 metres down is less predictable and if something happens to him then your solo anyway. Dont take that the wrong way, I know in practice you can rely on the guy you dive with but Im talking in a worst case analysis or risk assesment. I can see the value of streamling or simplifying but I believe you still need backup systems. To argue against that goes against logic, equipment fails.period. How you recover from that is the next question, this goes beyond diving ( Im an engineer by profession ). Ive diversed slightly, what I was after was logical, fact based reasons why bondage wings are at best useless and in somecases fatal. What I dont understand as an engineer is that someone can say the bungee cords restrict the wings ability to inflate underwater? if I can inflate them fully at the surface then I can do the same underwater, if the relief valve doesnt open on the surface it wont under water. The increased pressure required to inflate the bladder underwater is offset by the increased pressure on the relief valve before it opens ie, ambient pressure - that is an engineering fact not an irrational theory. Im not saying OMS is great or bondage wings are great, Im trying to make an informed choice, some of what Ive read goes against the experiance of OMS users I know, how many of the guys here with violent opposition to these wings have used them to any extent? Im very interested in your comments but please respond in an intelligent manner, Im not interested in some of the personal insults flying around :) Best Regards, Vinny.
