if u want max depth u must stick with any of the eric foster model...........hand made in england, cost varies as to what model u want................sold by mr bill at surfscanner
then the Headhunter PI by detector pro...........goes real deep and is priced just right
then like SandMan said.............the white's surfPI Pro and both garrett models - seahunter mark II and the newer Infinium...................infinium is somewhat higher and will doulbe as gold nugget machine if u so desire (all of the eric fosters will also)
NOW THEY TELL ME THERE IS A GREAT PI MADE IN FLORIDA - CUSTOM MADE - CALLED TR - not sure, but i can get back to u on it, there was just big artilce on the other forum about it and the guy, but i hear it only will work in florida.
