Goldscan coil question

[steve herschbach]

Hi,

Will the coil for a Goldscan 5 work on a Minelab SD/GP unit? It seems like this question was asked before and the answer was no.

Is there some kind of performance hit using a Minelab coil on a Goldscan 5? The Goldscan appears to be designed for mono coils. Is there any downside to using a DD coil on a Goldscan?

Yes it should. I believe you have to set the Minelab to accept mono coils. There is less electrical draw using a Goldscan coil on a Minelab. It is possible that the Minelab would not fire up because of the lighter coil load on the circuit.

The Goldscan 5 was designed for both mono & DD coils. The choice has always been for mono because they are a more sensitive coil than a DD coil is. A DD coil was designed to handle bad ground. Because of the placing & phasing of the windings they tend to cancel out ground affects. The trade off is a little less sensitivity, and in VLF units a little less resolution of discrimination.

The thinking was at the time, because the Goldscan 5 could do a lot of different things the the Minelab could not do, perhaps a Minelab user would purchase a Goldscan 5 to complement their main unit.That's one of the reasons why it was designed to fit Minelab coils. A Minelab user purchasing a Goldscan 5 would not have to out lay a lot of cash for coils.
