I’m sure you noticed today isn’t Wednesday. If you didn’t… well I’m helping you out… Today is in fact, not Wednesday. Okay now that we have that cleared up, you’re looking for my excuse, right? Well let’s just say a family emergency came up and on the true Wednesday I was spent. All is well now, though so let’s proceed on and just learn about this week’s SCUBAPRO Feature item, the MK21/S560. That’s a regulator in case you weren’t real sure. So glad I could help there!
This duo combination received the 2014 Gear of the Year award in Scuba Diving Magazine and was the Editor’s Pick in Sport Diver Magazine, April 2015.
So this excellent mid-range regulator system is lightweight and compact, but a very versatile breathing system that offers superb performance and value plus a whole lot more.
The MK 21 is SCUBAPRO’s super compact, balanced-piston first stage regulator. It is smaller and lighter than the MK25, using a smaller piston but delivering the same performance level of breathing no matter the depth or breathing workload. The design allows for resistance to freezing due to the thermal exchange while being a stylish polished chrome brass body. Wait a minute… what is thermal exchange? Basically it is the regulating of the air in the equipment. That means, the cooler diving temperatures you reach, the regulator regulates the air temperature helping to keep from freezing, definitely a bonus if you’re diving and still want to breathe, lol .
One of the features of the MK21 is their innovative “smart” hose layout. Okay miss blogger lady, what is that? The standard cap that comes on the MK21 has 4 low pressure ports that are angled (+/– 20˚) to maximize hose routing. Then there is a fifth port designated as as the high pressure port. Are you confused yet? Please tell me this blogger lady isn’t the only one confused! So I’m going to lay this out as if you are as confused as I was.
In this picture you see those ports? (they’re labeled). The standard cap comes with 4 low pressure ports. Now pick your regulator up if you need to, don’t worry I have the MK21 that is in the picture sitting on my lap as I’m trying to describe this… Typically, the “normal” if that’s possible, regulator usually only has 2 low pressure hoses coming off of it. So there are ports that are not being used. Remember your 1st stage sits on the tank and reduces the air pressure from 3000psi down to 140psi. Those are your low pressure ports. The HP or High Pressure port usually has your computer information attached to it (whether it be your transmitter or your computer to tell you pressure left in your tank). With me so far? I sure hope I’m with me.
