Jaw fatigue

[Brass Monkey]

OK this is probably a really simple one but I’m still not sure what to do. Having adjusted the weights on the YBOD hoses I still find the DSV to be positively buoyant to the extent that it’s causing me jaw fatigue trying to hold onto it. I’ve played with the weights but nowt seems to work. Any suggestions, more weight, shortening the hoses perhaps. I haven’t gone for anything this drastic yet, I’ll wait to see what comes back first. Had my first two dives on my own unit today and liking it more by the minute but would like it a lot more if I could sort the hose thing out.

As always any suggestions/positive comments are more than welcome. Even negative ones as long as they are funny.

Get some lead foil and make yourself some new hose protectors?

im not that familar with the box but with other rb's it just a case of turning the hoses a little to put a little tenion in them then they will inturn put pressure in the mouth piece which will turn up or down depending which way you turn the hoses....or its more lead!
hope this helps

Thanks John, that seems to make sense will give it a try.

Come on Dominic, I said "If they are funny".

Dave,
John's suggestion is good, turning the hoses around the outer locking rings either side of the mouthpiece should help. If you are new to diving the unit give yourself time to relax, I found that early on I had jaw fatigue caused by gripping the mouthpiece too hard between my teeth. After diving OC with a negatively buoyant mouthpiece the positive buoyancy of the unit's made it feel insecure and hence the tendency to hold on a little too tight.
I hope you sort the problem and enjoy diving the unit.
Dive safe.

Thanks Brian, turning the hoses does sound like the way to go. Your probably right about relaxing my bite on the mouth piece as well, there’s still a little paranoia about letting water get in. I won’t get the chance to try changing the attitude of the hoses until tomorrow (waiting for lime to arrive tonight) then hopefully I can get this sorted out. There are a lot of things I need to sort out on the unit. While on the course I used my instructors spare unit as mine was not ready. I was more concerned about learning/getting the drills right and monitoring the handsets than the actual comfort of diving it. Like any big change in diving kit it's going to take a while until everything feels the way I want it to. There will probably be some more questions; I'll just try to sort one thing out at a time. I was quite embarrassed when John told me about turning the hoses; it's so obvious I should have thought of this myself. Like a lot of other things in life we tend to look for the complex rather than the simple solution.


Thanks,


Dave
