I was just looking at the logs for jb-ms.com, saw a lot of hits from this forum and thought I'd check out the why of it. If you guys can talk Ron and Discovery into making a small coil for the new Fisher this might be of interest. Discovery currently makes a 5.5 inch coil for the Treasure Baron series that is the deepest small coil I've seen, and except for Minelab I've used or hunted alongside small coils from all the major manufacturers on their top end detectors. In side by side comparisons the 5.5 coil on a Cointrax air tested a nickel lying on top of the ground an accurately measured two inches deeper than a 5 inch coil on a CZ5 and almost equaled the depth on inground coins and Civil War relics, mostly .56 and .58 minies, of a CZ-70 Pro with 8 inch coil. On a Goldtrax it was a half inch deeper than my X5 with 7 inch coil on a freshly buried dime in loose sandy soil. Mr. Bill has used the Barons so he's aware of the performance level of the various coils, if that performance could be carried over to the same coil made for the ID-Edge you would have a winner.
Discovery has made the 5.5 coil for over 10 years, already have the molds and other equipment needed, so there should be little or no additional tooling cost. The only added cost should be tuning the coil to the Fisher and changing the connector. In a discussion on another forum about using other brand coils on the Barons, George Payne said a higher frequency coil could be used by installing a resistor with the apropriate value in the coil. If that's true, and I certainly don't doubt George Payne, it shouldn't add that much to existing costs. Assuming the only added cost would be the addition of a resistor and differect connector, the problem in convincing Discovery to make the coil would be how many they could reasonably expect to sell. The 5.5 Discovery coil is more costly than most other small coils but some of us feel they are well worth the cost, in fact I have two so if one goes bad or I damage one I'll still have one available without having to wait on repairs.
