Scubapro mk 10

[TDR1]

Hello,
I bought this new in 1987 in Littlehampton, Sussex in the UK. I used it regularly up until 2006. I had it serviced last summer, after being in the shed for four years. I usually dive a twinset now with Poseidon Xstream reg's. But last weekend I dived it. I didn't quite realise how cold the water was it turned out it was 4 degrees.
My one overriding question is,
Is it safe??
I seem to remember having to squirt a tube of grease into the holes on the first stage. Should I still do this?
I have to say I feel like Jacques Cousteau when I dive it.
Ty.

I dive a MK10 full of grease to 5*c with no problems. I trust it completly.

You could pack it with either silicone or an O2-safe lube if you're planning on using higher concentrations of O2. If your MK10 is one of the later ones that has a groove for the spec boot, you can try to find a boot and that will help hold the grease in place. My doubles set up is a pair of packed MK10s.

Mk10s have been my mainly used, for years mainly without grease.

And Aussie made Airdive regs of same design with grease.

Thanks,
I think I'll get some silicone grease to squirt in the holes.

For anyone that's interested, probably no one, it turns out I've got a Mk X Dual balanced. This was only sold in Europe apparently.

This one: European

So that's just a MK10 with a balanced adjustable, correct? What else could dual balanced mean?

How about the gold plated MK10? I was a little surprised to see that, I thought Europeans were supposed be smart! hehe..

 

[TDR1]

Yes, thats the one. Although all the writing came off after about dive 10. Apparently the first stage is balanced to.
Gold plated mmmmm!
Now I don't know who told you Europeans were smart. Thirty odd countries who all hate each other it will never work. Although they all hate us , the English, the most.
The one thing that surprises me the most about my reg is that I've still got that plastic blue key thing! How I haven't lost it after 25 years I'll never know!!
Thanks

My first regulator was a Mk X/Balanced Adjustable purchased new in 1987. I purchased a new Mk X/G250 in 1988, and a second Mk X/Balanced Adjustable shortly after that. I upgraded two of the Mk X's to Mk X Plus's sometime in the early 1990's and at about the same time purchased a D400 second stage to use with one of them. I still have all of these regs, still dive them, love them. Prefer them--except in very cold water when used with high pressure (3500 psig) tanks.

After experiencing a couple of free-flows on deeper, cold water (~40 degrees F) dives during back-to-back dive outings to Lake Huron (USA) shipwrecks using my Mk X Plus's on "cave-filled" HP tanks, I decided to purchase Poseidon Odins to use for these types of dives. I considered filling the Mk X Plus's ambient pressure chamber with silicone grease to reduce the likelihood of 1st stage freeze-up, but ultimately decided that I wanted cold-water regs which had a diaphragm 1st stage conservatively rated to 300 Br (to more reliably handle the cave-fills) and which could easily deliver air [sic] at extended range depths. (As you probably know, the early 1990's was a time of "deep air" and "advanced deep air" diving in some locales.) Moreover, at that time, there was some concern about the Mk X's internal HP O-rings extruding when the Mk X was used with HP tanks. The switch to "Hyperthane" O-rings in the Mk X, then the new Mk X Plus, followed by the Mk XV all were attempts to address these concerns, iirc. (I hope someone will correct me if I've got this wrong.)

I hope this is of some help.
