Wondering if anyone has done a side-by-side comparison of the new Scubapro MK25/X650 and the discontinued D400 using the MK25 to see which ones subjectively breathes better. I did a side-by-side comparison of the MK25/S600 and the MK25/D400 yesterday in the ocean at 64 ft. with a water temp of 56 degrees.
The S600 breathed the easiest I have ever experienced with the adjustment knob only turned out to the half-way position. I thought it couldn't get much better than that until I put the D400 in my mouth. The D400 seemed to have an edge because the breathing seemed to feel much more natural and the breathes were delivered to me with hardly any effort on my part at all. Now I just need to turn the S600 knob all the way out and compare it to the D400, but I still think the D400 is going to feel subjectively easier based on its inherent design and because I have used the S600 enough to know what to expect. I don't think I can wrong with either reg, but I would like to learn more about the X650 now.
One dealer says the X650 has a major design flaw in the angle of the front housing that covers the diaphram (or some kind of degree angle flaw), but another dealer tells me with the latest diaphram, etc. upgrade that the X650 has its problems worked out. At this point, I don't know what to think.
I have heard from one person that the X650, when it works right, actually breathes better than the D400. Can this be possible? Is this really true? Are the problems worked out now? If it breathes better than the D400 AND the problems are resolved, then I don't see how it could get much better!
I will continue to provide updates on any experiences that I feel may benefit this Board. Any input on the X650 vs. D400 would be greatly appreciated. I don't need any further test results on the S600. It's a great performer, and I will use it too.
Thanks!
