saturated once bubbled...
Welcome,
First things first. The marks are great units, they are however like an old harley......they work well, get attention and require a good bit of maintenence. The down side is cost and parts availability. For a new rebreather diver an Inspiration or even a topaz may have been a better fit. (just my opinion). If you havent purchased it yet I would do a great deal of research prior to the purchase. They are great and I love mine to death, but to be honest the huge majority of my dives are spent on the inspiration. Parts are reasonable(and available for that matter). If I go down its usually only a couple days before I can get parts in to repair it. Tanks are easily filled anywhere that has pure O2. Alot of shops will give you fits about filling the spheres. It will be best to get a small booster and fiull them yourself at home. Either way way you will be happy, maybe happier with the "mark", but the inspiration is definately a more practical daily diver...just my .o2
I am planning on a field trip to visit Kevin and learn how to tear things down and put them back together. I really want to learn just exactly how everything works. I am just hoping that Kevin, Patrick, Tracy et al. can keep me in parts. Please let me know of any other good sources for parts.
I am good to go for local fills. For when I travel, I think Gordon's mini booster might be just the ticket

I have never been accused of being practical, and I think that sometimes shows. I have a feeling that I am about to take on quite a project in just about every way. I do already own the Mk 15it should arrive on Wednesday

Saturated, one thing I need to figure out before training is how to attach a harness and wing to the unit. If you would be willing to share, how did you accomplish this? Have you heard of other solutions? I would really appreciate any help you might be able to give.
Todd.
