OxyCheq Wings OxyCheq makes one of my favorite wings. OxyCheq wings are practically indestructible. OxyCheq wings are well balanced, streamlined, provided buoyancy in the correct areas, minimized drag, and built to a very high standard. Johns Quick Tip’s: Wing Differences Specific Use Wing versus Multiple Use Wing This is one of those catch 22’s the best wings are made for specific circumstances, ie, if you are diving doubles buy a wing made just for this. This specific use wings tend to have the most streamlining. The multiple use wings however do work great. The can be used with singles or doubles and do both very well. Wing Shapes U Shaped They should call this an upside down “U” but oh well. This is the way wings used to be made they are still great wings. They are low profile and work just fine. O Shaped This is the newer style wings. The reason behind the “O” shaped wing is no matter what angle or inclination you are at the air in the wing can move throughout the wing with ease. Johns Quick Tip’s: Keep your BC Working 1. Inflator Rebuilds More dives are lost to this malfunction than most other things. The inflator is easy to rebuild if you have the proper tools. You will need an inflator tool and some o-rings. There are four o-rings inside (2) 006 (1) 012 and (1) 112 plus one 011 on the inflator nipple. The inflator is easily pulled out as an assembly, once it is out you need to hold the button and put a wrench on the back. Then you take the center shaft out the two o-rings here are the culprits. Clean the corrosion off the shaft and body, put new o-rings on, lubricate and reassemble. Then of course test before you go back in the water. 2. Wing Punctures (Bladder Wings) This one can not be done at the dive site. You will need a BC Tool to remove the corrugated hose mounts on the wing. Make sure before you do this that your wing has a bladder some wings are bladderless if this is the case just jump to the Aquaseal step. You will have to dissemble the overpressure relief. Once this is all done, pull the bladder out and reassemble it. Now blow the wing up spray the wing with a bottle of water with a little dish detergent mixed in, this will help you find the leaks. Check carefully usually if the wing was pinched it has holes on both sides. Mark any holes with a permanent marker. Now deflate the bladder and lay it flat on a table. Get a scotchbrite pad and scuff up the area. Remember you are just scuffing it up do not go crazy. Once scuffed, just put a dab of Aquaseal on it. If you do not know what Aquaseal is, shame on you what kind of diver are you! After this is done and the wing has dried for 24 hours inflate it and check for leaks again. If you do not have any reassemble the wing.
