My daughter last used this about 10 years ago. The regulator is a Scubapro ML R190. It has been stored in my basement until now because we are moving. She says it worked well the last dive. I do not want to pack her gear around any more. Make me a reasonable offer, you pay for shipping. If the gear turns out to be non-functional I will refund your purchase price via PayPal transactions. Thanks for reading. RobView media item 202957View media item 202956View media item 202955View media item 202954
