Garmin 910 xt during swim leg (Page 2)

My guess is that the depth at which the 910 loses signal is pretty shallow.  It's why the original 310 would not work while OWS until they upgraded the firmware.  From what I gather, the firmware tells the 310 and the 910 to not look for a continuous GPS signal stream while in OWS mode, but try to "piece it together" from the signals it gets when your wrist is out of the water.

If GPS worked while under water, any waterproof garmin would work for OWS while attached to your wrist.  Before the 310 firmware upgrade and the 910, the only other solution was to put it in your swim cap.

Yeah, can't be more than a foot or so, as my arm does not go that deep when treading

So the solution is...if treading water, just before starting you need to lift your arm out of the water, and do your best William Wallace impression.  Seems fitting just before the mass start scrum.

Pretty much everything MonkeyClaw said I do as well.  I've used it in 4 OWS tris last year and will plan to use it start to finish in a handful upcoming this year.  I use the multi-sport mode.  If it's a water start I will lose the GPS signal if I'm treading water too long so I will raise my hand every so often to make sure I don't lose the satellites. 

I have not had a problem getting the wetsuit off of my wrist.  Those that are practicing wetsuit removal, are you doing this completely dry or wet?  I think the wetsuit comes off my wrists easier when my skin and the inside of the wetsuit is saturated.  Maybe it's not actually the truth but it seems that way to me. 

Also if it is a wave start or a beach start where we run in, I just start my watch and not worry abou tthe total swim time knowing it could be 10-30 seconds too long.  Not a big deal over 2.5 to 5 hours if you ask me.

This is what I do as well, because it makes it easy to see when I'm in my aerobars on my bike.  But I have found a couple of times that my watch hits the bracket for my aerobottle, and presses the lap button to put me into T2 (multisport mode).  Very annoying when I notice right away, much more annoying when it takes me a while to notice.

Is there any way around this?

I don't know what quick release strap all these people are talking about, but the one for my Garmin 910xt has ZERO chance of getting kicked or pryed off in even the most brutal OWS.  It's basically like a pill bottle where you have to push down and turn very hard to release it.  It's NOT coming off in a swim.
