Hi Digger x. The A 250 is a great machine. If you go to "Metal Detecting" then "Brands" then "Garrett" and type in "my guide ace 250 coin hunting" you will find a write up I did on using the A 250 as a coin hunting machine. It's a great way to learn and fun, I've moved on to searching much older sites, made some upgrades and focus on relics now. Good luck!
