i have a xt 70 with a 6"dd 18,75 khz and a 10"7,5 khz dd ... im going there to make vacation.
so which one shall i take to get the best results in coins jewellery and so on . i know the 18,75 khz coils isnt going so deep.. so i dont know if i should prefer the 7,5 khz one with a higher and deeper range with a sens of min 25 where it can detect any small stuff like necklets, but on the other side ive the problems with the mineralisation so getting more false signals
