This is a discontinued dive computer by Citizen. Her battery cannot hold any reserve now but still can charge. My guess is she needs a battery change. I have used her for spare for some of my diving trips and she works well. Condition wise is about 85-90% with swirlies. Complete charger and paper for a very reasonable price usd200. This a private sale and no refund or return.
