There is a story going round of new coils for the exterras to be released soon. Is this fact or fantasy. There are obvious gaps in the coil choice eg a 10 inch DD eliptical 7khz would be a good one for getting into tight spots for coins. Another good choice would be a lighter 10 inch DD round coil. It is surprising when one of the selling points is the machines lack of weight, and they build a heavy brick like DD coil, which is to the same mold and weight a the old Explorer coil which has been reduced in weight couple of times over the years on that machine. der! I would like to see some larger eliptical coils mainly for covering more ground eg for beaches or relic hunting,but then again they would not want to be too heavy. Hopefully Minelab will let some other manufacturers build some better coils for these machines sometime soon. seeya Neilo
