Matrion, if money is tight and you can't afford to make a mistake on your first purchase, take the advice of Mzjavert.
Don't be in too much of a hurry to purchase and detect. The stuff in the ground will be waiting for you.
Get a detector with an audio response that you can understand (let alone tolorate for long periods of time).
In addition, take into consideration the supporting tools that you will need, like a good digging trowel/knife, pinpointer, as well as a finds/trash pouch.
Honestly I don't know how someone can tolorate turf hunting without a pinpointer of any kind.
That said, learn to dig a 3 sided plug in your yard, flip it up, retrieve the target, and return the turf with little or no indication you dug a plug.
Sometimes the plug doesn't cooperate, but leaving little trace you've been digging is important. Some people "coin pop" with a screwdriver on the shallow targets.
But if you are going deep, you need to learn the technique. It becomes a point of pride when you can put everything back and not tell exactly where you dug when you go back the next day.
Its easy to do, you just don't want to experiment in public places only to be told you aren't welcome anymore.
