for under 250 dolars?

Used Minelab Sovereign would be my vote.

Check around Ebay to get a cheaper high end detector or just check like Basspro or Cabelas.

thanks ^_^

The honest answer would be:.......There isn't one.............you generally get what you pay for..........I'm not familiar enough with the Minelabs, but you can get a used White's XLT for under $400 sometimes on ebay.

New detectors:

White's Prizm II
Garret Ace 250

thanks ^_^

Fisher F2 would be my choice.
