scubapro mk 21

[Candiru]

Has anybody had a look at the new scubapro mk 21. It seems to be similar to the mk 25, but without the turret. It mentions that there are two heads available. Im interested in one that has a fifth port type option out the bottom. Any thoughts?

Look at the SP museum section (or timeline) on the Scubapro website. The description says the piston is smaller (which surprised me), if true then it is not just a MK-25 without the turret. Also the pay attention to the angle of the ports they change depending on the head.

Good idea on the scubapro museum. Thanks.

I recently went through the Scubapro Technician course being held locally last month. The rep talked about the new MK21 quite extensively. The MK21 is similar, but not identical to the MK25. There are a few small differences such as the piston is smaller, there is only one o-ring on the piston, and there is no rotating turret. One head had four ports on it, and the optional one has a fifth port that is directly out the bottom for technical divers hose routing on doubles. As a technician the most important question I had was if it is similar to the 25 will it use the same service kit. The answer was no, SP is making its own service kit for it so I will have to have another batch in stock for service work.

Any idea whether this will be a standard seat or another unique (proprietary) seat?

If I remember correctly from the Tech course I did at DEMA, it has the same seat as the MK25. I would need to look at the exploded diagram I have (at the shop, of course) to tell you for 100%.

It's the same HP seat 10.101.161 for the MK21 as for the MK20 - 25
