    It’s pretty light. And breaks down small. My wife and I can put our units with a can light and computers in a carryon bag each. Mine’s sitting on the bench in the garage put together. I’ll weigh it tomorrow with tanks on if nobody knows the weight and posts it before then.

    Haven't seen any updates on this thread in awhile. Any new experience with the fathom to relay?

    Yes. It's a POS. I hate it. It's totally ruined OC diving for me. I went and did a 2 hour dive in Ginnie on OC. I had to worry about how much gas I had in my stages and backgas, I had to hear all of the noise of our exhaling, I got cold after a while, my mouth got dry. And the most annoying of all was I realized that I always listen to my wing dump valve to judge how much I've dumped. Never used to be a problem. Spent 8 months on the fathom and can hear it beautfiully. When back on OC I couldn't hear it at all, making dumping gas not super accurate. So my buoyancy on OC sucked too. Stupid fathom.

    In reality, I've got about 30-40 hours on the unit now and I love it. It's simple and problem free and the needle valve is a dream. I think with the meg conversions available soon, there will be alot more people adopting it.

    Cool. If you email Charlie, I'm sure he'd find some time or someone to do a demo. Or contact Ken Sallot or Jon Bernot. I've got two units. I'd be happy to let you check them out if I'm in cave country when you are. You can just shoot me a pm.

    It really is a dead simple unit. The thing I like about it is that many of the major components are off the shelf items. I can easily replace the adv, elbows, counterlungs, etc without much being proprietary like other brands. The proprietary things are the can (which if you break, I'll buy lunch and beers), the head, and the needle valve. The head is pretty indestructible. The hud batteries are user-replaceable (and on the outside of the unit which I like). All of the orings on the head are pretty standard and easy to find. You can replace the locking mechanism yourself with a piece of weedwacker string. It travels very light and small. We can fit the entire unit with lungs and hoses, computers, wing, and can lights in a carry on bag. The backplate has to go in a different bag.

    That's awesome. Thanks for sharing. Yeah- I'm going to try and get in touch with someone to possibly demo the unit.

    I noticed you mentioned you have two of them. Any reason for that? Different configurations for wreck and cave, perhaps?

    One for me one for my wife. I was never interested in CCR because I felt I was the stereotypical over 40 guy with a beer gut that offs himself on a ccr. My wife needs closed circuit for the cave research she does, so as I started learning about ccr I realized how much safer it can be in the caves compared to OC (way more time to figure stuff out). An instructor friend got a fathom and showed us how simple and easy it is. I was hooked at that point.
