Thoughts on MK25 EVO/S620Ti for me

[rjmd]

Okay, me a contrarian, you do not need the performance of the Mark 25. Ten people honking on it would not consume it's capabilities. And that is not much exaggeration. Also, you do not need a a double sealed diaphragm regulator. The only thing inside the ambient chamber is a spring that is coated and isolated. This sealing of a diaphragm regulator adds about 30% to the weight and size and costs with no real benefit for the diving that you propose. And a Mark 11 Evo is fully capable of performing the occasional cold water dive. A diaphragm regulator, by design, the important moving parts are sealed by the IP diaphragm. I would prefer the G260 or the C370 for a second stages.

Correct on the most part, I do not need these at this time. I do want to accommodate for if my diving lifestyle changes though. For example, if a few years down the road I pickup diving more frequently in NY where it's cold and there are allot of quarries, then the MK17 seems to make more sense, but that is just a what if scenario and not a binding decision driver.

I think this thread has swayed me off the MK25 Evo and onto the MK17 Evo 2.

I was looking at the weights on the Scubapro website and it seems the MK17 Evo 2 is only 12.7% heavier. Maybe the recent Evo 2 release made it lighter? As for the size, I was looking for a picture of both next to each other but can't find one.

• MK17 Evo 2 DIN - 2.38lb / 1.079kg
• MK25 Evo DIN - 2.114lb / 0.957kg

The Mark 17 Evo II is lighter than the previous Mark 17 Evo. I do not have the specs handy.

I have the 17 evo2 and the 11 evo and I would pick either over the 25, i find I have no need for a swivel turret and that it just adds unappreciated length, the MK 19evo is great if you need/want the swivel

I would lean toward the 17 evo2. but I really do like the 11evo since it can do 99% of the 17’s job as well and it is slightly more compact. I also find the concept of one regulator somewhat odd

So do I, it is very perplexing. Divers who think they can only have one outfit, one pair of fins, one do all BC-wing/BP and goodness, one regulator!!!!!!!! They are simply kidding themselves.

The Mark 19, Mark 17E II and Mark 11E are functionally the same regulators for all practical purposes, the Mark 11E is sealed, the Mark 17E II is double sealed and the Mark 19 is double sealed and has a turret (and it is big).

I am just going to sit on my Mark 11 and Mark 17E for the time being because my favorite, go to, do any dive, travel friendly, absolutely rock solid reliable regulator first stage is the simple Mark 2 Evo . Coupled with a balanced second stage it is all anyone really needs for sport diving. But we like new shiny toys and like to spend $$$ on them.

One regulator, phooey on that .

I am planning on buying DIN and just having this DGX DIN-to-YOKE adapter on me if needed. Will this be a headache when dealing with Yoke-configured tanks or is it relatively straightforward?

Someday, long from now, on the shores of a placid sky blue sea with pink sand beach and rainbow colorful artificial bio-engineered (by AI) creatures swimming about, some 50,000 years passing, a team of Homo sapiens domesticus will unearth a shore diving site. They will marvel at how intelligent we Homo sapiens sapiens must have been just as we marvel over Homo sapiens neanderthal technology. Then one will stoop over, chip at a rock with their laser pulsed rock hammer and a Scubapro Mark 2 Evo will fall free. They will pick it up, astonished with it's utter simplicity and lack of parts. Surely some alien technology (by then we will have conquered the aliens and probably eaten them). Then they will take it for a dive .

One last post and off I go. It is cheaper to buy Int and then buy the DIN kit. It takes me about 5 minutes to swap between the two. I never see a reverse kit available to go from DIN to Int. But I can get the DIN conversion kit cheap on Amazon. Those Int converters basically suck IMO. The "dust" cap that Scubapro currently provides is the same piece for DIN and yoke, it is universal.

The only negative, for me, of the MK 2 is hose routing.

The reverse from din to yoke is eBay where you can pick new take offs for about the price as buying the DIN kit.

My second picture shows a DIN to yoke adaptor on a DIN, I never us it because it just better to convert between the two. As Nimrod points out you should always buy the international because the DIN conversion is readily available and cheap.
