I'm looking to sell my Shearwater Petrel Gen 1 wrist computer. This is a great primary/backup unit to use for advanced open water or technical diving. The unit unit has under 75 dives now, and was stored in a pelican case when not being used. It is in like new condition, with only minor scuffs on the faceplate. I am asking $500 for the unit, and will ship domestic US at no extra costs.
