GP/GPX coil experiment risk?
Posted by: bklein

I’ve read some messages indicating putting an incompatible coil on these machines could damage them. I tried a beach hog on my GP Extreme and it worked ok. Now I’d like to try the coil from my whites DF. Risky?

Generally, you can use the Minelab coils on the Whites, but NOT the reverse.

The Beach Hog I tried was a TDI coil. So what’s the deal, Whites coils just don’t perform well or there is risk of machine damage? The GP coil is already fairly low resistance so current should not be an issue with a Whites coil.... I feel the DF coil already doesn’t perform on a DF as it should so I am curious to try on the GP. Bought the Gp with blown front end though....

I have no idea of the reason....just stating what the general consensus is on several Minelab discussions.

I got a reply from Carl on geotech and he said whites coils are ok to try but have higher coil resistance so GP coils should do better on the GP machines.
I’ll post how things work out.

That explains why they're not recommended for the GP series. Higher coil resistance means less current though the coil, and a weaker magnetic field into the ground. That would mean less depth.
