Similar coil for a GP or GPX

[WesHawkins]

  Since I’ve been hearing about how the coil is one of the biggest differences and advantages of the GPZ 7000 All the detectors give off a transmit signal and recieve a return response, I’m wondering could a similar coil be made that would give some advantage to the GP and GPX machines.

There is a lot of hype with coils, they are all mostly the same, improve one thing and lose on another.
