My PADI open water certification is only a week old . . . I am having trouble emptying the bladder of my Dive Rite wing. The only ones wearing these wings are my son and me, everyone else, including our dive masters, are in jackets. I have had two involuntary ascents while I try to dump air. I have learned to get vertical to dump air while holding my corrugated hose way up high and depressing the "big" button . . . . I have not yet pulled the valve located at the bottom right. I may try this tomorrow while horizontal. Everyone in my party has a low opinion of this wing. The dive masters think it is inappropriate for me. . . I would appreciate kind and constructive suggestions!
Although the discussion seems to have devolved into a BP/W vs jacket 'discussion' (some might say monkey s**t fight), I am really not sure that is the heart of the issue in the OP's case. Unfortunately, some critical data are missing from her narrative, including but not limited to 1) what specific wing the OP is diving, 2) whether the DMs (who apparently are diving in jackets) are at all familiar with BP/W BCDs, or simply view them as some strange, alien contraption, ans 3) whether the son, who is apparently diving the same rig, is having the same problems, or doing just fine. When the OP indicates that everyone in her party has a low opinion of the wing, that doesn't necessarily mean those opinions are informed or valid, because everyone else is also in jacket and may suffer from the same subjective reaction to that alien BCD.
So, putting aside the 'low opinion' issue, and the dive masters' thoughts that it (and it is not clear if it is an opinion specific to the wing, or to BP/W rigs in general) is inappropriate for her - we really have not been told why they think that - perhaps Dive Rite is not a brand they have ever seen, or a brand that the resort / dive shop doesn't carry (and therefore must somehow be entirely substandard).
There is at least some suggestion from the OP's comments that the problem may simply be a lack of diving experience, lack of familiarity with the particular gear, and receipt of either bad advice, or even sub-optimal instruction - who told her to '
get vertical to dump air while holding my corrugated hose way up high'? Why wasn't she taught that, when you are swimming in good horizontal rim, and need to bleed a bit of air, it is much easier to lift your bottom up and inch or so and vent through the butt dump. This is a technique relevant to all BCDs - I use it with my jacket all the time. Why wasn't she taught that when swimming in good horizontal trim, you don't have to go vertical, all you have to do is rotate 90 degrees to the right, so the (left) shoulder dump is now the highest point on the wing?
It is too bad that she has not returned to add clarification to her comments, and to let us know how the next day of diving went. It is often stated that equipment is not a solution to a skills issue. Perhaps, a useful paraphrase of that sentiment would be that equipment is not the culprit when there is a skills issue, either. Everyone has a learning curve. It appears that the OP is merely near the beginning of that learning curve. We all have to start somewhere.
