IST R20 regulator

[martzak]

Does anyone have experience with IST regulators, r20 in particular.
I'm trying to buy a back-up regulator on a shoe-string budget and found a balanced piston regulator made by IST, model r20 ( I think it's environmentally sealed???).
joediveramerica has 3 positive reviews for this particular regulator.
I just want to make sure this reg is rated for cold water (>34F), any one KNOWS if that's the case???
Thanks.

I'm going to answer my own question on this one in case some else would like to know.
I bought this regulator from joediveramerica. Dove it for the first time in early April at Haigh Quarry, Kankakee, IL. Had no problems, water temp. was 40F, depth 45' max. Breathes easy, although there was a little gurgling sound when I turned my back towards the bottom...however, no water in my mouth.
I'm going to do a deep dive next.

I have one for a backup regulator,it works great and breathes great,I used it this weekend and was still going strong,I doubt it is rated for cold water being a piston reg. but I have not had any free flow problems diving in 40-50 degree temps.

It is a very good regulator, and well priced. IMHO, make sure the IP pressure is adjusted properly.

Thank you both for your input.

This is what scubadiving.com had to report on the reg.


IST SPORTS PROLINE R10 & R20
IST Sports' brand-new R10 adjustable and R20 nonadjustable regulators dominated breathing simulator tests in this price group. The R20 not only earned a perfect score, it was able to exceed 300 feet at the maximum breathing rate while maintaining a work of breathing of only 1.0 joule per liter--an outstanding achievement for a budget regulator. In-water tests show the R20 to breathe dry in all positions. The R10, while delivering fair breathing performance in the swimming position, has a tendency to breathe wet in a heads-down or face-up position.

sounds pretty good for a budget reg.
