Terry,

It's a good fix but it's also a half *** band-aid fix. Why does a reg needs to be stuffed with grease if it was designed right in the first place that and it's their most expensive reg? Detuning a reg so it doesn't free flow, gimme a break. What's next making the regs outta bio degradable material so that if you don't come in for a yearly servicing and it fails it isn't their fault?

SP has great engineers and great designs but when bean counters come into the picture, things go FUBAR real fast.

De-tuning is a crock.

My M1 will almost breathe on it's own.

The grease, however is a nice idea. To prevent freeflows, the first stage ambeient chamber can't have any water in it, but needs to be at the same pressure as the outside world.

Some manufacturers do this by continously leaking a small stream of bubbles, some by packing it in grease, and some with rubber seals. Personally, I like the grease, since it doesn't crack, tear or fall out of place.

Terry,

Grease is a good idea but its really a messy solution and Christolube is really expensive.

Look what happen to one M1 reg during testing:

"Alas, the silicone started to leak out of the first stage after the third day and it became very messy, so it was probably not ideal for use in these conditions."

Even cheaper regs like AQUA-LUNG TITAN LEGEND LX or the Mares will perform better than the MK25 and not free flow so go figure.
 
I don't sell anything, so I don't really care what anybody buys, however the Christolube only oozes out for a little while after service, then stops, and it is effective in preventing freeflows. The "expensive" part is pretty much irrelevant, since the reg only needs service every 2 years, and shouldn't be more than maybe $20 for enough to fill the reg.

From what I saw of the article, the "test" they ran didn't actually include using the regs in cold water, so I'm not sure how thay could determine which were suitable for use in it.

When I first started diving it was with a SP LDS. When I was looking for a reg I started doing my research on the various regs out there.

My LDS told me about the Mk25 regs and when I questioned him about the cold water characteristicts he told me it could be modified to work as well as the Zeagle I had been looking at. I then asked him why I would want to fix something that is brand new so it will work properly. His next statement drove me out the door, "Zeagle is crap". Sorry folks, this kind of answer is not an answer to a specific question asked.

Granted, I walked in the door fully loaded with information and a I believe a good LDS would have tried to sell me his product and failing that, would have offered to find the product I wanted. But, never ever slam a product a customer wants, they just might have taken the time to do their research.

Bottom line, if it needs to be fixed, modified, etc out of the box, it's not worth the money, period. That does not mean things don't need testing and adjustment.
 
In my opinion SP screwed up when they replaced the SPEC equipped regs with the TIS system. It just does not work with 100% relaibility on the Mk 20 or Mk 25 in tmeps below about 45 degrees F. The sad thing is that they had an excellent SPEC boot on the MK 20 that would have worked just as well on the Mk 25 (before they switched to the finned swivel cap). All they would have needed to do was switch from silicone grease to Christolube.

SPEC equipped regs were messy to service, but they were very relaible in very cold water.

On the other hand, if you have a newer finned swivel capped Mk 25, or even a mid production Mk 25 with the larger oval shaped ambient pressure holes, you can't just stick grease in them as ther eis nothing to prevent the grease from coming back out - especially when it's sitting in the sun in 100 degree weather.

I'd love to see SP reintroduce Chistolube using variant of their old SPEC kit for the Mk 25.

CompuDude,

Don't worry I know what you mean and DA Aquamaster thanks for your info although it doesn't make me feel any better since, I have a couple of MK25s and this is really just another POS marketing bs from these companies.

I don't dive in cold waters so I guess my Mk25 should perform fine but it really sucks to buy a reg that only works under certain conditions and it really sucks when the reg is supposed to be the top of the line model.

Looks like Apex will be getting my $ in the future.
Tell you what, I'll take those horrid MK25's off your hands for a reasonable price and you can go buy whatever Apekx regs you want and not have to worry anymore, ok? :eyebrow:
 
CompuDude,

They aren't horrid just not up to par. Well depends on what a resonable price is, but I'm game even though i just got them less then 3 months ago.

I agree with you, but with shipping and customs tax, I'm out of the bid.

Have one, wouldn't mind another for a reasonable sum. :)
