You got a G250v? Whats the 1st stage you use with it?
If I was to buy a new reg set it would be the G250v and Mk17 ( even though its only cosmetically different to all the other G250's out there).

I actually have 4 G250V second stages and 3 MK25 first stages....and love them...

Colour me green with envy.

I really like SP's design philosophy in regards to their 2nd stages.
Take the old 109 chrome reg. Its a adjustable design but unbalance.
Then there is the 156 which is the same but balanced. The only difference is in the air barrel. You can buy a G250 service kit and a G250 spring ( same as a R190 spring AFAIK) and convert the 109 to a 156.
The only difference between a G250 and a 156 is the G250 is plastic and has a VIVA adjustment. Not to be confused with the poor cousin G250hp (hp= "High Plastic" content since it has a plastic air barrel and the G250 and G250V has a chrome plated brass one).
I am also pretty sure the old 108's use the same valve set up as the R190's and R265's etc

So even though many of these regs are 50 years old you can still get parts for them and even upgrade them with new parts from the newer regs.

Currently I use Mk25's and modified 109's ( 156s) on my twins and Mk20's and modified 109's/G250's on my stages. And a MK2 G250 on my Dil/bailout tank for my rebreather.

Greg.... in the nicest possible way, you are such a geek.

[ChuckyBob]

Thats quite funny coming from someone who chooses to teach for a living. Although probably quite true.

But really I posted nothing that any half a*** reg tech cant tell you. ( and there seems to be plenty of them around!).

I always tell my students.... geeks are employable, but nerds aren't.... it's a fine line between the two.

It's a bit like the line between tax avoidance and tax evasion!

And I do have to admit at being a dive-geek... just not about regs, as long as they work then that's fine by me.

[ChuckyBob]

After the problems I have had with professionally serviced regs not to mention the cost involved in keeping 6 1st stages and 6 2nds serviced it pays to know a little about regs when you want to service them yourself And sticking with one brand helps.

[justsimon]

Why do you have 6 regs?

[ChuckyBob]

2 sets for my doubles.
2 sets for my stages (one O2 clean one not)
1 set for my Rebreather bail out/DIL
1 1st for my O2 for rebreather
1 SS1 Atomic octi/inflator for rebreather.
Plus a few more floating around that dont get used.

Yes I could cut down and reconfigure the setups as required for different diving but most of my regs owe me very little and it would be a shame to sell them.

Ebay is a great place to buy regs.
The ones to look out for ( IMHO) are the 109 156 and G250's. They will usually be pair with MK5's or MK10's and can be landed in NZ for $100-$150
The MK5 is a pretty old reg. Its balanced but not a high performance reg flow rate wise. Also it may have a low pressure (2250psi) yoke on it and it has a different DIN fitting than all the other SP 1st's. So you are better off looking for a MK9 or MK10 but not a MK10+ as these have a rounded edged piston and dont hold IP as well.

A good MK10 and G250 will breath exactly the same and have the same hose routing options as a new MK25 and G250v but you could have 10 or more MK10/G250's for the same price as a single MK25/G250v

[justsimon]

Fair enough.

Which is the best reason really.

Do you know what "MK" mean for their first stage ?

[ChuckyBob]

Always assumed it was Mark
