Purchased in 2013 and used for about 30 dives. Last dived in 2017 and has been stored since then. It has never been submerged. Upon listing, I checked the charger and rechargeable battery that came with the purchase, but they did not work. Therefore, I am selling the main unit only. To check the operation of the main unit, I have inserted a 18650 3.7V 2200mAh lithium-ion battery with a protection circuit that I have on hand, and confirmed that it lights up. I have priced it lower because I cannot include the rechargeable battery or charger. Please understand that this is a used item before purchasing. Please note that I may use used cardboard boxes for packaging when shipping.
