I have been using my Coinmaster GT in competition hunts for the last couple of years. I just bought a Fisher F75 LTD and had it moded. I will still use the Coinmaster for hunts as I like how it feels and I am comfortable with it and I think the Fisher is overkill for 2-3" coins Anyway the Coinmaster takes 8 AA batteries and I decided I wanted to change them out for lithium. I spent a lot of time to find a 11.1v lithium polymer pack that would fit 99% were too big. I finally found a 2800 mah pack that I could fit in the battery trey and still remove it. It just plugs in like the old one. I had to gut the holder to fit the battery, so I bought a spare so I can still use AA's if necessary. The battery cost about $16 and the new AA holder cost $15. If anybody is interested I can supply pictures and sources. All in all it works great.
