For a trimix dive computer, this is a good deal, particularly for someone starting out. I have one I keep in case one my my Shearwaters dies. Worth pointing out a few things:
- Unless I've missed something (I have an earlier version), it only does VPM. VPM kept me from getting bent for some time but Buhlman is better. Use decent dive planning software to see the differences and set conservatism on a VR3 to achieve a reasonable match on a dive by dive basis and things will be OK, most likely. This is my opinion, worth what you paid for it. Make sure your instructor will accept it if you're in training.
- Battery life is not great. Carry a couple of spares and O-rings, and pay attention to state of charge. I used to use about 3 SAFTs per season, sometimes more.
- It's an orphan. No repairs, no support, no parts. The buttons can be broken if you aren't careful. I probably still have a couple of spares and at least one can be had for postage. I mean, mine is still the backup to my backup, so I need at least one spare button. Mine has been rock solid since new.
- Make sure you get all the unlock codes to be able to use the functions you need. Keep them somewhere safe. Keep them in 3 places that are safe, because when they're lost, they're lost.
- Some people find it complicated to use. I think that once you go through the drill a few times it's not really that bad. I think that for its time it got a lot of unjustified bad press. YMMV.
- I added a 1/8" bungee in case the strap came loose. Cheap insurance but the strap never did come loose.
All that said, if I needed a trimix computer and didn't have one, I'd buy it at the asking price. It would tide me over at the fraction of the cost of a Shearwater until I could afford one, and then it's still a decent backup.
I hope both the seller and prospective buyers find this helpful.
