The individual I was talking about that had the problem was using a G250 second stage that was de-tuned and was using a Gavin scooter. She intends to replace it in the very near future. I use an R380 instead. It's adjustable as well and easy to breath, even at depth - I had an o-ring failure in my primary that forced me to switch to my backup. Other than the shock cord pulling at both sides of my mouth, I didn't notice any significant difference.

I live and dive in Quebec so yes I dive cold water year round and yes I do use a scooter ( I dropped surface swims right after I dropped PADI). I have found there are two keys to the proper functioning of equipment, read the manual (the 250's have adjustments to de-tune them) and find a good service technician (if the reg is set-up properly its a non-issue). I will service my regs at least once a year and even more frequently depending on how they feel. Do I care about the cost? maybe you should ask what price I put on my own life, think about it.

Case in point - Just this weekend I was diving with someone that had a balanced secondary on the backup around the neck. We were playing with some scooters and I watched the individual scooter off in a cloud of bubbles as the reg started to freeflow. Mine is not balanced and I've never had that problem. A similar situation is also possible in higher current. Kurt > The TX40/50 are balanced. I think all the Apeks are. > > Not sure I agree with this no air balanced for secondaries, anyhow.
