Falconman515 I own a V3i and I am not happy with it. It finds coins alright but when I go head to head with my brother and his Etrac, he is the one going home at the end of the day with all the silver and rings. Plus he always beats me in total clad value found. I haven't found a half in months and he has already found 5 or 6 this year. My local dealer tells me I am overthinking my V3i. I am an engineer plus I am always working on computers so I tend to over analyze everything. I have used the Etrac and a XP Deus when they first arrived here in the US. I am sold on the Etrac with its ability to seek out the silver but I am having a hard time turning down getting a Deus. It is super fast and extremely light weight which is exactly what I need. I am not a spring chicken anymore and with all my ailments I need the lightest machine on the market. The battery being in the coil really concerns me. I tend to hang on to every machine I have purchased because I have fond memories of what I have found with each one. If I do this with the Deus how long can I expect the battery to last? I have not found a post anywhere addressing this issue. Good luck with your decision. Once you have made it and purchased it lets us know if you are happy or not and why please.
