Tusa RS-130 (cold water)

[drifter136]

All of the very positive reviews and great price have me very interested in the RS-130, especially as a first Reg. My question is, with it being a piston based reg and not environmentally sealed, what would be the coldest water temp you would feel comfortable diving in with it? If it ends up being colder than what I am willing to dive, then it's all good. I would probably be OK diving in the low 50's as long as it wasn't too cold topside. I think I have read that once you get to about 40*F is when you really need to start considering an environmentally sealed reg. So, I am guessing that I would be fine with the RS-130, but just wanted to get your thoughts. Thanks!

I dove with mine in 20C or 75F water in one of the Cenotes. It was pretty cold for my taste. Anyway I have the RS 130 and am pretty happy with it.

I have never dove that reg., but it appears to be of good quality from a few divers comments previous, and you would be just fine in waters in the 50's with no issues.

manual says not below 10 deg C so that is dont go in water below 50 deg F not sure if you would be safe going below that but I wouldnt try it

Great, that's really good to know. I think I am set on it as a first reg., but keep having it in the back of my mind on 'what if' I ever dive in water getting down into the 40's. However, with my complete wussyness towards cold, I do highly doubt that I would ever dive below 50's even if I were to get a drysuit.

Rox, thank you for the recommendation from the manual. So, I just need to be sure to stay about 50*F, which shouldn't be a problem at this point in my diving career.

The manual says 50F limit but I wonder if anyone tried it below that threshold without problems? Thanks.

[Empacher]

any recommendations for a good cold water reg?

Dive Rite makes the Hurricane (RG3500) and the RG3000 with ICE kit that both would work great in cold water. You can also look at the Scubapro MK17 for cold water.

Scuba toys has the Dive Rites, and now the Hurricane is on sale at a really great price.

My brother and I did a shore dive in Lake Michigan when we cleared the breakwater we hit 43F water temps. His RS-130 worked just fine for our 30 minute dive
