DIR regulators

Mal Bridgeman · November 30th, 2005, 10:05 PM

As I understand it the 2 "approved" regulators are the scubapro mk 25 and the apex ds4.

Again AIUI the rationale for DIR kit selection is about choosing the best hence having 2 bests does not make sense to me.

How were these 2 choices arrived at?

TIA

The regs you mention are good regs. There is no "approved" list of DIR regs. The regs you mention are very different. The Mk25 is a piston, the DS4 is a diaphragm. The Mk 25 costs nearly three times as much as the DS4 (in UK).

Performance, configuration, adjustability, compatibility etc. are all deciding factors when choosing a reg.

Take a look at this guide........

this will help you to make a decision.

Most of us are using Spro Mk20 or Mk25 or DS4's

Personally, I'd go for the DS4 (for UK diving)

I thought one of the "stipulations" was that a second stage had to be capable of being stripped and "repaired / fixed " underwater.

That knocks a lot of regs out straight off of course.

Please correct me if I'm wrong ?

Bob,

Question, apologies for ignorance but who is Paul Larret ? Obviously very well informed but I just haven't heard the name.

If I need a kick for that question please feel free next time we meet

Cheers

Yes, you're right about the 2nd stages, but we're talking about 1sts here.

Paul is/was on the DIR-UK team until he moved to Bermuda a couple of years ago. He was back here during the summer and dived with us.

What is the cost of a MK25 and a DS4 in the UK - then please let me know euro or pounds so I can covert to USD. And also is ScubaPro Lifetime parts over there? And is Apex 2 years or less (service vs inspect)
Just wondering????

I have been moving over the scuba pro for lifetime parts - annual services were just costing to much.
