Took the F-75 out to lunch again at the local park. I have been playing (ongoing and always) with the settings. Today I had the discrimination up to 53. Notch at 36 (which gives full "Nickel" readings), the mode to bottle cap and the tones to delta. The sensitivity I boosted up to 60 as it seemed relatively stable at that setting. Some chatter, but easy to dismiss by watching the VDI and the confidence meter.
First hit was a Nickel. I was happy as this was the first I have found in the week I've owned the F-75 and gives me some confidence in the notch setting. It was a 1964 at 4 inches and gave a steady 27 in "X"ing over it. The next coin was a 1967 dime at 7"! I was happy with this as the ground was drier today than it ever got all last year. This park was flooded badly (as was the whole town) and there was 2" of fine, gooey silt over much of it last summer. Four more dimes came next, all between 6" and 4", for a run of five in a row. I stopped by the volleyball court and found three cents just under the surface. Someone keeping kids bust or busting my chops.
So, for the lunchhour hunt: nine coins. ZERO trash. I didn not dig any weak or unstable targets, though I had plenty of foil, tab and cap visuals and audio blips. I hunt this park regularly and I have no doubt the two older and deeper dimes have been under the coil of my Musketeer many times. This park is full of pulltabs and screwcaps, and what a pleasure it is to be able to spot a coin. Granted, I mab be missing rings and likely will go back eventually and reshoot with lower discrimination . . . or not. The post '82 cents corrode badly in this spot (grass fertilizer or something reacting with the higher zinc alloy). I ignored some of those that gave the three-number-hop from 58 to 61, which I have discovered is the F-75 way of saying "messy cent below". The dimes all read 70 or 71, and the early Memorial cents read 72 or 73 (so far).
I'm usually not so uppity or lazy as to avoid cents or iffy signals (that's where the good surprises are) but I had an MRI Monday and learned I have a torn meniscus in my left knee and kneeling, squatting or hunkering down in general is kind of uncomfortable; and corroded cents don't have the lure they once did.
I'm keeping a logbook of the VDI readings for various objects and have started a line graph of where each falls on the scale.
