"Vintage" Aeris 750 GT air-integrated (when used with transmitter--not included), hoseless, nitrox dive computer. Good condition with minor scratches on face that are invisible under water. Works great! I just dove this as a backup a few weeks ago with zero issues. Please note this is an older computer and has a few "vintage features": does not automatically count down safety stops, can not be set to current date (doesn't go high enough in years), still allows 60 fpm ascent rate regardless of depth, set to pp02 of 1.6 atm (not adjustable). None of these keep it from being a great, fully functional computer. It still uses the same no-deco algorithms as current Aeris/Oceanic computers. Uses the same Aeris/Oceanic/Hollis transmitter as current computers. Has user replaceable non rechargeable lithium battery. Includes original case, user manual, and quick reference card. You can find the manual on-line if you search for it and want to read up before purchasing. $60 plus shipping (should be less than $10). Sorry, US sales only. Let me know if you have any questions.
