Just received my Garrett Ace 150 yesterday,used it for alittle while and find it ok but very nasty on the pinpointing.Is there a better detector than the Ace 150 or Ace 250 at about there same price?I never hunt beaches or on sand only detect on school grounds,playgrounds,people's yards.Looking forward to all your suggestions.Thanks! Steve. P.S. Doesn't have to be fancy and can be any brand, just want it good on finding coins.
