Morning Sabre: K but which model of OKM are you thinking of?
First) what kind of terrain are we talking about? is it rocky, hillside, swampy, brushy, mineralized, salt, adobe, etc.
Second ) what are we looking for, and what possible size ? Au, Ag, or ?? check the response curve on the different detectors for different metals..
third) How much is allowed in your budget?
fourth) What is your personal physical, mental condition? Are you wiling to study?
This will do for a starter, but if you are looking for objects of say a lunch box up, then the economic balance will be in favor of a ground balancing / cancelling two box unit. ----->
say a discovery 900. in the $400 500 range.
The Lorenze XP2 with a 14" coil is impressive, but @ $ 5000 ?
A Garrett Infinium , also a pulse detector, will give it serious competition @ Sale prices of $ 950.
For 6 - 8 ' on a large object, I tend to place the Garrett at the middle, it will do just as good as a Lorenz with the same size coil, at a considerably lower cost. The only difference is that Lorenz has more coils to choose from.
