A friend gave me a mares pnumatic speargun that is about 10 years old. He could not find the pump for it. He has disappeared scence giving me the gun. Last week I finally had a chance to us it. The group I went with had an ex owner of a dive shop who gave me the nuts n bolts of shooting it. Of course now I'm hooked. I want to get a pump and would love to have a manual so I know how to opperate it, pump it up, and do rutine mantance on it. The gun held air for two years between my getting it and using it. would rather learn about this gun then buy a new one. Wife does not dive and dive time is presous do to three little ones owning our world. Please help if you can. Thanks
