I have been hunting Civil War relics for the past year or so with a 505 I bought second hand that has the stock 9" concentric coil on it. I was thinking about ordering me a new 705 and was wondering what your opinion was on the best coil to get that would work on the 505 or 705 for Civil War relic hunting? The ground I hunt does not have all that many mineral's in it that I can tell from my ground balance numbers. Thanks for the info.
