“Haven't had a chance to use it yet but very excited to give it a try since carrying a scuba tank on my back after 5 spinal surgeries is out of the question. So far I like what I see and have heard about this system and it should be perfect for my intended use of just off shore shallow diving. I bought the dual package so my grandson can take a cert class and then join me diving for some easy stuff on our Maui trips yearly. I like the convenience of the backpack, the light weight and that you can fly with it.”
