This new Coiltek Battery system is taking detectorist by storm. This new system is less than 15 ounces making it the lightest Minelab SD/GP/GPX battery system on the market. The unit can mounted to the side of any Minelab metal detector with the use of the short power cord (sold separately). The SD/GP series unit has a three position regulator toggle switch that allows you to choose between two operating voltages (6.7 or 7.3 volts). You can now run your Minelab SD at a higher operating voltage that allows you to get better stability, better sensitivity to smaller gold and more depth. Since the GP series have a built in regulator, it's best to run this system at 6.7 volts, but running the 7.3 volts will not harm the metal detector. On my minelab I get 7hrs out of one battery. I picked it up from www.nuggethunting.com
