Welcome to SB and back to diving. I think you’ll find that being on SB is just like diving, there are rules but they are hidden in .02 font just like the back of the PADI dive tables.
You are sure to hear all about the biases that exist but be aware there is a strong technical bias on SB that shades everything. Not a problem as long as you are aware of so when the buy a shearwater computer , backplate and wing and use a primary donate long hose or you’ll die advice starts rolling in you are not surprised.
But seriously buy a shearwater or you’ll die, no seriously I’m not kidding.
Funny, in most cases where I am diving to any real depth, I actually do prefer a hard back pack & a wing. I've been going that route for over 20 years.
I'm not familiar with shearwater computers. Most of mine are from Oceanic. I guess I have some reading to do.
Thanks for the perspective.
