Hi Glen, RIGHT BACK AT YA with the WELCOME HOME!! GLEN, I served in Vietnam from June 71 to Mar. 29, 72, and I did my In-Country Training in Cam Ranh
Bay!! Are you familiar with TIGER LAKE in Cam Ranh? I spent most of my tour in I-Corp, at a place called Phu Bai/Hue City! But, i spent my last (3) weeks in
II-Corp, City of Nha Trang!! What a BEAUTIFUL AREA of Vietnam that was!!
Anyhow, getting back to metal detecting! Like I said, I have been researching the F-75, because I am waiting to sell one of my detectors, before i replace it with
an up-grade!! So, it will probably be a couple of months before I make a purchase. I have a NAMVET BUDDY that is a FISHER/GARRETT Dealer, and he is a
Die-Hard F-75 User!! Earlier this month, he gave me an outside demonstration with that detector, and I was VERY IMPRESSED!! So I am very interested, unless something else comes out before I make a purchase. I'm not trying to act like some expert or even someone who is knowledgable about the F-75, but you might want to TRY the 4-Tone Hi ID with your current settings!! With 4-Tone Hi ID, you will get a Hi-tone on those types of coins, and 3-Cent SILVER & Half Dimes. But,
you will get the HIGHER Hi-TONE ID on most SILVER Dimes and Larger SILVER Coins! My buddy hunts with that tone, and he and his hunting partner, who he hooked up with an F-70, got (3) GOLD DOLLAR Coins within a 2-month period. Hope this info HELPS YOU!! HH, BEST OF LUCK, Les Robinson
