Why yes, yes I do know EXACTLY what kind to get ;-)
Go to your local Home Depot, and in the gardening department, look for the little blue handled AMES digger. I think was like $10-15 and it blows the $40 schwinn handled digger away. While you're there, get yourself a treausre pouch, complete with belt, for $13 (same one you find on MD'ing sites for $39.99, and the digger fits perfect too!)
Send a portion of your new dug treasures to me for my finders fee ;-)
Just because we're in a hobby does not mean we should pay all these "treasure hunters" retail x5 because it says "metal detecting" somewhere on the product!
The treasure they seek is in your wallet!
