Delete the minelab modes? or just reset everything? I've been testing alot useing my test garden along with learning how to use/setup the machine. So far i like it as it alows a person to set it up for the diffrent types of hunting as well as conditionds. One thing i noticed is that the "coin" pattern seems to be open to all the coins from around the world. Has anyone come up with a pattern just for US coins? Or two diffrent patterns say 1800s and 1900s?
