I have i just started metal detecting and bought a minelab x terra 705 with a 7.5 khz (coil).
Glad to hear you are getting a start in a wnderful outdoor sport!
Now for the questions:
1.. What general area do you live?
(Just to get an idea of potential ground mineral make-up).
2.. What type of hunting do you plan to do? Urban Coin & Jewelry Hunting, Beach Hunting, Relic Hunting, Gold Nugget Hunting, etc.?
3.. Why did you buy the Minelab X-Terra 705? What encouraged you to selet it?
4.. Did you plan to get one or two additional search coils? If so, which one(s) and for what intention?
5.. Out of curiosity, what other makes or models did you consider?

I think the coil faulty because when i touch it on the ground i beeps.i have turned the sensitivey to about 20
More questions:
1.. Did you check the ground area first to make sure you are not lowering the search coil over a metal target? That would cause a 'beep.'
2.. Did you first adjust the Ground Balance? Depending upon the mode and other settings, lowering the coil to the ground could also cause a 'beep' if the GB was off, specially too positive.

Lowering the Sensitivity is usually NOT the way to eliminate a 'beep' from a coil-to-ground orientation. It might be if way too sensitivity and the 'beep' is actually move of an 'overload' response, but the general answer would be 'No'.
If you are having such an issue you should:
1st.. Make sure you read the Owner manual, completely, cover-to-cover and understand everything it is explaining.
2nd.. Locate a metal-free area to check and adjust your detector.
3rd.. Adjust a proper slight audio Threshold hum, then select he All Metal mode and adjust the Ground Balance to be as close to 'spot-on' as possible. I do all of this at the highest Sensitivity level with any detector I use, and only reduce the Sensitivity if need to gain stability if there is a lot of EMI.
Then your detector should be operational. If it isn't and the coil seems to 'beep' if you tap it or touch it to the ground, three is a possibility you have a defective search coil.
