Just bought the sniper coil and tried it out mixed result found some coins but dug a lot of trash.Are you suppose to swing this fast or slow it seems the response is slow.When the bell tone rings you have to slow way down and search for it.It seems noisey.I used electrical tape on cable and is also tight against rod checked battery and tried it with low and high sensitivity.Has anyone got some pointers or information on how it responds?Seems to find cans easy and scrape easy.Thanks
