This scenario presents another potential reason for utilizing primary donate: If you have in your mind giving up your primary and automatically moving on to your secondary you avoid the above as you don't forget about your secondary. It is automatic to go to your secondary when you lose your...
As I have been reacquainting myself with diving I have fallen (partially) under the ScubaBoard spell
When I trained we did buddy breathing as not everyone had a second (Edited to fix) second stage.
But I see the efficacy of the primary donate and have gone to a 5' primary to ease that way

Finally realized as much as I love the mountains, the ocean is where I belong. (And luckily I now live in Honolulu!):D
Reading through the information on this forum in conjunction with a bunch of snorkeling has me ready to refresh my training and get back underwater.
Thanks to all of you...
Seems like the place to give you a heads up to check for my support.
I've enjoyed very much all the information I've read over the last couple of weeks.
Thank you
