I have the seaquest pro bc with the surelock and im not so sure about it. After about 50 dives, ive had 1 dive with a issue. It was in Honduras, and i was looking for a entry point in the Odysee wreck. I started to put my head in a open cover hatch on the deck (picutre me going down head first into the hatch) and after I looked around for a second, I reversed motion to siganl my buddy and something caught the weight pocket and pulled it out of my bc. I start floating up, while the weight went into the ship. I dumped my air, and struggled to swim back to the hatch for something to grab onto. My buddy went in the boat and got the weight pouch for me. It wasnt dangerous, but it sucked.
In the future, im going to get a bp/wing for penetration wrecks and drysuit diving here on the pacific coast, and use my seaquest for warm water and easy rec dives. I really believe you need different sets of equipment for different diving types. my 2 cents..
