I have to say I have found more silver and gold with my 555-D, 1265X and 1270 then I have with the F75LTD. And not saying that its a bum detector or that its not picking it up, but I think people get to in the tone ID, ID #'s on the screen, Disc settings, there's lot to be said when you get a solid 22, with a high confidence meter reading and its a tin foil # and you passed the little girls 14K gold ring up cause it's totally reading foil, where as with the ding and dig machines solid hit you dig. Now to be fair I have found a lot of old,old deep coins with the F- 75 all those bell and whistles don't help that much sometimes in and old park or school that is super trashy unless your max Disc like WV62 says, that work but that's with main item with the analog machines. Believe me I'm using the F-75 for 2 years and I go out at least 4 to 5 days a week (retired) for 4-5 hours min. and work the old cellar holes and foundations but I'm not coming up with all this stuff the video and the pics these guys are finding in there worked out places and I'm using 3 different size coils all kinds of setting and I'm not a newbie at detecting been doing it over 30 years. just think of what we pass up when we don't dig a lot of the 35-55 pull tab range, sure set the disc at 4 or 6 mono or 3 tor 4 tone with high sen. and get 30, 45's on the ID do I dig every 1 or how many do I pass up and how many were the good stuff. When you set the 1265X at just a hair under 5 and it went off yes it could be a tab but an nickle or GOLD, but it went off so you dug it and it was a ring now the digital range is roughly 26 to 40. Some times technology isn't the best thing tried and true always seem to prevail. but I'm not giving up on the F-75it is a top notch machines and it will tell you whats in the ground but we have to choose what to dig, Maybe there's just to many choices to pic sometimes........................
Just my opinion.
