Scubapro MK 17/S555 Regulator Review

For the cold water diver, hassle-free regulators top the priority list for extreme dive environment. Icy cold waters demand thermal protection and the right equipment to easily maneuver your diving exploration. Scubapro MK 17/S555 also known as the “Icebreaker”, that’s according to the guys at Scubapro, is designed for tough cold waters and extreme dive environment.

Scubapro MK 17/S555 Product Features
Anti-freeze components
VIVA system
Air-balanced flow valve
Compact and lightweight materials
1st stage type: balanced diaphragm
LP ports: 4 ; HP ports: 2

The diaphragm’s design requires less maintenance than do other competitors. Also, ScubaPro developed VIVA (Venturi-Initiated Vacuum Assist) for ease of breathing. So as the air is pulled into the second stage casing, a vacuum is created behind the diaphragm. In turn, the diaphragm depresses the lever that maintains the poppet open for a “power assist” breath. In addition to the VIVA, the air-balanced power inflator valve means you’ll have a steady stream of air, regardless of the pressure in your tank.

According to scubadiving.com, “This reg earned the highest possible scores on the ANSTI breathing simulator and praise from our test divers en route to earning a 2006 Testers’ Choice rating.”

Now, let’s hear some great reviews from our seasoned divers:

“I just got this product, and used it on my two week dive trip. It held up for all the dives – never had a single problem. It never free-flowed and it was easy to breath, even when I was below 500 PSI. Couldn’t see anything really wrong with it. A great choice!” – Zach of Silver Springs, MD

“Definitely recommended. I bought two. They have held up very well for over 100 dives so far without any drop in performance. They have not given me any problems diving in cold Great Lakes waters. The best thing I can say is that I don’t have to think about these regs. They have not given me any problems yet. Hose routing is not ideal, especially the way the HP ports angle in towards the diver. This puts a sharp bend in the HP hose as it comes out of the first stage. This happens on Doubles and Singles. Note this is the same first stage as the S600 without the adjustment knob, so breathing performance will be equal.” – bigCountry of St Louis, MO
