Remove air bubbles in ascent in Travelpac Voyager

jcfahy · Oct 12, 2013

Please help me with my technique in removing trapped air bubbles in my Travelpac Voyager. I love the system but about 1 in 5 dives i struggle to remove all air at my safety stop. Clearly my fault with technique but I do go vertical, hold the hose above my head, lean back, dip my shoulder and even use the left dump valve. When this occurs my dive buddy helps my squeezing the bladder and then the safety stop is easily completed. Any suggestions: perhaps my poor mounting of the bladder on the tank or???
I am committed to the system but fill stupidly frustrated.

Many thanks for suggestions.

sounds like you are working too hard to maintain your safety stop. you might need to add a couple of pounds of weight to help with the safety stop. you would be amazed what as little as 2lb will do at the end of a dive to help you maintain the stop.

try it and see if it helps.

Thanks, Tom. I generally do a weight check and my buoyancy feels about right during dive. I am surprised how much air is released on the odd occasion when my buddy helps squeeze the bladder after I thought air was eliminated but I was too buoyant. The back wings do tend to trap air between tank but I am frustrated. I suspect that it is caused by the way I mount the rig on occasion - perhaps imbalancing the trim.

Sometimes I have the same problem. I know there is air in my bladder but I just can't seem to release it no matter what normal technique or orientation I use. When this does happen the best solution seems to be to get into a position that would normally vent ok, add air to the bladder, and then release the air. Adding extra air seems to break the seal that then allows the remainder to vent. Not ideal but for the frequency that it does happen, it is certainly better than carrying extra weight.

Thanks Mattoau. I will try this at about 10 m and see if it helps as it seems logical to me.

I've noticed on my wing that the bladder can crease, depending on how it was packed, trapping air. I second Mattoau, it sounds like your shifting all around at your safety stop but, if you can try "sloshing" around the air so it "breaks the seal" as Mattoau said, it might dump more efficiently.
