There's probably some context here that we're not getting. GUE recognizes SM is a useful tool; it's just not their default configuration. Most GUE divers doing exploration projects in Mexico do it in sidemount.
This is outside Kiril and the team of GUE Cave SM divers here in Florida.
It’s always some mystery instructor.
I assure you, NONE of those guys are looking to turn down anyone’s money.
Honestly now that I know the area I can believe it, knowing the reputation of the GUE community in that area.
But that area IMO is an exception. I know the Cave Country and Mexican GUE communities don't have that issue.
