I have heard that our local PD uses non-law enforcment divers to retrieve non forensic items from local waters (ponds, lakes, rivers) My question is what type of dive training do I need. The estimated cost for classes and my own equipment. I think this would be very interesting to do. Not to take away from the pros. but we have a small PD in the area. If I am wrong oh well it would still be cool to learn how to dive. One of the lakes in this area is man made by the railroad many years ago for the old steam engines. It would be interesting to see whats down there one day. Thanks
