Just scored a Minelab Goldseekers 15000...how obsolete is it?

[hobbit]

Just picked up an old Minelab Goldseekers 15000. I bought it mainly because I am a Minelab fan and I know it was their first unit. I assume it operates at 15KHZ, so I am thinking it might be pretty sensitive to small nuggets. How would it stack up to the X-terra 70 with the 5" dd 10KHZ coil for instance? In short is this unit in any way still viable as say, a back-up or loaner detector? Thanks in advance.

Used to own one of these way back about 1988 or thereabouts. It was a better unit than a Whites Coinmaster of similar vintage. The guy I sold it to has about 4 coils for it and was still using it in Australia around 5 years ago. With a small coil it will find a one gram size piece a few inches deep if the soil conditions not too mineralized. Nuggy
