[QUOTE="Elsewhere, post: 325721, member: 8519"] Could be an option to get hold of a reeds lucky lark battery, sound enhancer as there are a few coming onto the market with a lot of people upgrading. They are 11.1v but they are adjustable simply by taking off the lid and adjusting the blue pot switch. I currently run a 3500 at 7.3 v and even though these machines are voltage regulated a good consistent voltage goes a long way to a consistent threshold. Replacement battery is not cheap so try and get one that has a relatively new battery. I get about 14hrs per charge. Commander 11dd is still a great coil for all gp detectors and agree that even on my 3500 the 12 evo in all but very quite ground is a handful. [/QUOTE]
