[QUOTE="Ronk, post: 105270, member: 3914"] i saw an article where he used a frisby for the coil holder but anything plastic would be fine , you could also make the coil on formers and then cast it in epoxy resin so make a mold for it the other idea i have for myself would be to make my detector compatible with minelab coils and going as far as to make my connections to the coil the same fitting and same for battery if it going to be external , however i am thinking i will use lithium iron batteries as they are very light and the battery on my old 2100 is a bit of a pain about BFO detectors they were invented for use in mine detection during ww2 i think, but they are wrong for gold and precious metals the best type for gold detecting are pulse induction these inherently ignore noisy ground which has plagued other types of detectors I am considering trying to build my own detector and have been looking at circuits and also looking at youtube videos of them working , nothing i have seen so far really tickles my fancy I look forward to seeing results here , if i go ahead and start to build something i will post it here cheers Ron [/QUOTE]
