Rege-PA just reported on the DP Forum that a new White's detector is on the way - the White's Goldmaster 24K. I have put a specification page together for the new model and will update it as information becomes available.
In short it looks like an updated and slimmed down version of the GMT put into the new MX7 packaging. There is now a backlit LCD display with target id information, advanced ground tracking technology, dual tones, and more. The new Goldmaster 24K comes with both rechargeable batteries and a battery holder for eight AA batteries. The stock coil is the 6" x 10" DD and there is a two coil package option with the 6" x 10" DD and a 6" round concentric.
The White's Goldmaster 24K announcement is so new that there are sure to be changes and updates to this page very soon - all information and specifications are subject to change!
