Hey Now! Thank you for taking the time to check out this used Tigullio 52 Airtrak 1st & 2nd Stage Scuba Regulators with Parkway Escort Nitrox Dive Computer that is up for today's auction. The regulator set looks to be in great condition with minor wear n tear from normal use and storing. The dive computer worked, but was in storage for some time and will need a new battery (See pics).
