Shopper how far down can you go with this reg? and whats the lowest temp you can have it in ? thanks
Brett H Mares rates their regs to a max depth of 162 feet, that said if you go to 163 feet and beyond your reg is not going to just stop working, they are used at extreme depths all the time. As for the cold water rating, the certification only specifies it is rated for use below 50 degrees F. This regulator is set up and ready to go for extreme cold water service, if you follow proper cold water diving procedures with this reg it should work great as long as the water is still liquid.
