You be fine, great reg both first and second stage, cold won't be a problem.
Good luck with your open water

Mares MR22/Abyss has been around for many many years. And the reason is that it is an excellent reg.

I am not a big fan of their cheaper stuff (Axis, ect.)


For you as a new diver doing checkout dives, one scenario to be aware of:

You will be going in and out, doing all kinds of drills on the surface, and your second stage will be dangling in the water.

Abyss does not have venturi adjustment knob. Not that it needs one, just explaining what to expect.

Every time a properly adjusted second stage submerged in the water with mouthpiece up, it will let out some air. Due to venturi effect, which is employed in many second stages for better breathing, it might stay open and free-flow.

As there is no knob to turn the venturi effect off, Abyss is likely to free-flow, while dangling on the surface.

Do not let this freak you out or suspect a malfunction. Just cover mouthpiece with you finger, if happens.

I remember my checkout dives in a quarry. As if I was not anxious enough, while walking into the water, just when I got about waist deep my second stage started blowing million bubbles, and I was staring at it and had no clue how to stop it and what is causing it.
Fortunately, some guy, who was not even a part of my class, mimed to me “take it out, turn mouthpiece down, and submerge”

Every once in a while I see questions from a newbie about similar situation here on ScubaBoard wondering whether the reg needs to be serviced. I thought I’d let you know beforehand.

Good luck with the OW!

Excellent reg.
Very solid and reliable.
Treat it well (rinse well after each dive) and it could last you a lifetime

Had one for years and breathed it at depths that do justice to its name.

The MR16 (that looks like a saussage) has the exact same internal geometry in the first stage, but less metal, so is lighter.

Oh, yes, I almost forgot

ok im sold on this one

Mark Ellyatt a technical dive instructor based in Phuket, Thailand achieved the deepest ever solo scuba dive recorded on Thursday 18 dec 2003.
The descent into the depths took a mere 12 minutes and Mark spent just 60 seconds there, collecting a marker to verify his record-breaking depth. But the ascent took six hours and 40 minutes.
The regulator Mark selected for the dive was the Mares MR22 first stage and the Mares Abyss second stage.
The regulators performed flawlessly despite the almost freezing water temperature below 200m and hight gas demands.
The dive marks a milestone in deep diving, by being the first solo 300m dive that ended without decompression complications.

The mares Abyss is mostly the same reg as the Mares Ruby with out the ruby and a different type of seat. These components can be swapped out in the future for a upgraded reg.

I doubt you would see any noticeable improvement in performance. To me, Ruby was just another fad designed to fill a certain market niche that does exist and potentially can generate some extra revenue for the manufacturer.

Just my humble opinion, not based on actual experience with Ruby. The only time I've seen the reg is in Fla. at some small and seriously overpriced shop in a locked glass cabinet.

As a side note, neither Ruby nor Ti-Planet is any longer in the current Mares model line-up.

Just remember the dive was sponsered my Mares, they would have gone over his kit with a microscope before this dive
Don't get me wrong, it is a excellent reg.

Also Mark nearly died, I think about 18 months before this, when he tried to break the record.

Scubatoys still hold stock of the Ruby and Ti planet if anybodys interested :06:
