Steve Herschbach Posted April 22, 2015 Share Posted April 22, 2015 Going off subject , but battery weights and more are at http://www.detectorprospector.com/forum/topic/680-minelab-ctx-3030-and-gpz-7000-weight-comparisons/ Running the GPZ without an incorporated battery would indeed ruin the balance. The existing battery is fine - we just need more of them! 1 Link to comment Share on other sites More sharing options...
Norvic Posted April 22, 2015 Author Share Posted April 22, 2015 There is a aftermarket battery system available for the SD,GP,and GPZ, in OZ, locates the battery & speaker on the control box, seen a fair few fellows using that. Battery only had 4 hours reserve but getting rid of cable is a godsend. With tech gains there may become a way to cut the coil weight on the GPZ, that would be a top mod, bet the aftermarket guys are working on it. First with a light coil will be laughing.
