I am in the process of putting my complete dive system together. I have pretty much decided on purchasing Scubapro for my first and second stage and my alternate air source will be the same make and model as my primary / second stage. I will be purchasing the set up from my LDS and will lean heavily on what they suggest but I want input from as many of you that will chime in.
I have researched the different Scubapro regulators and in my opinion "with a grain of salt here people" the MK17 with 2 G250V's and appropriate sized hoses will pretty much let me dive any and everywhere I want (not interested in chipping a hole in the ice yet).
I am getting back into scuba now that I can truly afford it and over the next few years want to get into light tech diving (cavern / partial wreck entry) and want to have gear that will support that.
I would like to hear from you if you own this set up or if you were thinking of this one and went with a different set up. All are welcome to give your two cent.
Thanks in advance for replying because I know this question has been asked before.
I don't own the 17/250 setup, but I know from research that they perform very well. The MK17/G250 will be great. I would however order them in DIN format since you are looking to get into tech/cave diving activities. You might also want to look at the Apeks DS4 or Tek3 stages with XTX50 or 100 seconds. I love mine. I can also recommend MK25/S600. Enjoy your kit and diving adventures.
I have a Mk17 G250V setup, and I'm very happy with it. If I had it to do again, I'd probably get the same, unless my LDS became a HOG dealer, in which case I might look at a HOG setup, since I've seen many very positive reviews of them and my only complaint on the Scubapro stuff is that I'm not allowed to do any maintenance myself if I want to keep the warranty intact. The warranty and the proven track record of the Mk17 G250V are certainly pluses IMHO.
The regs you've chosen are among many that would make you vary happy for years to come.
I think a more important decision is the choice of the regulator tech rather than any particular brand or model (within reason).
If you really like your LDS, and they are a Scubapro dealer, then you've made a great choice... if they sold Apeks, Aqualung, Mares, Zeagle, HOG, etc., you'd also be making a great choice... in other words there are lots of wonderful regulators to choose from!
Diaphragm 1st stages make my heart go "pitter patter" (there, I managed to work it in afterall, knowone ).
However, after recently rebuilding a Scubapro Mk5 (the "father" of many current balanced piston regs), I do see the allure of balanced pistons.... nice design, a bit easier to rebuild, elegant lines, nice performace....
I'm still married to balanced diaphragm 1sts perhaps, but balanced piston 1sts may now be my exciting "mistress"
This rambling is intended to get you looking at all the alternatives.
If you dive warm or temperate water, a balanced piston design (Scubapro Mk25 / G250V for example) might also be worth a look.
No wrong choices for the most part.
If you are moving towards doubles and tech diving, looking into DIN vs yoke connections, which design allows more options for hose routing, and be sure that the 1sts and 2nds both accept "standard" hoses (so you can change hose lengths easily).
The MK17/250V is a great setup, and will serve you well. As a PSD diver, we dive MK17's because the primary chamber is sealed, preventing contamination. In my personal diving, to include (very) deep as well as wreck I prefer the MK25's because the balanced piston flows better/smoother at depth. I am also a Scubapro Tec and when I went to class they showed us a clip where the attached over 100 2nd stages to a MK25, it supplied air with no problem until it finally froze after 10 minutes. Unless you really push the envelope, you will be happy with either set-up - each has its strong points but both will perform more than adequately in normal use. I do agree with the DIN comment - if you continue on with your dive education you will end up with DIN regs or conversions.
