Has anyone had experiance with this new "humidifier" for your reg.
http://www.apollosportsusa.com/Produ.../Biofilter.htm. Apparently the air from the tank has like .01% humidity, thus causing the dry mouth and in some cases dehydration which leads to post diving headaches. I've had that and it sucks. This device is supposed to add between 30% - 70% humidity in the air making for a more comfortable dive.
So here's my question? Is it worth it? has anyone of you used it before? I am hesistant to purchase something that could complicate my dive if it fails. How reliable is it? Just throwing this out there.
