I bundled up and headed out this morning to a house that was built in 1948. A nice lady that I just recently met give me permission to me detect her yard. It's just down the street from a large corner lot where I've found nearly 150 wheat pennies and lots of silver coins. I was really pumped this morning, because the site looked great. I pulled out my ole trusty Vaquero with the 9 x 8 inch coil attached and started my grid search. It wasn't trashy which is a good thing, but I wasn't finding any wheat pennies. I was finding lots of memorial pennies and a few clad coins. Finally towards the end of my grid search I got that sweet soft audio tone and I was pretty sure it was silver before I even dug. I popped a 1946 Rosie. Not convinced that there was only one silver coin in that yard, I decided go to the car to change search coils and do another grid search. When I got to the car I changed my mind and grabbed the AT Pro instead. I did another grid search with it and only found maybe 2 or 3 clad coins. The Vaquero didn't leave much. Fed up with that lot, I took the AT Pro to fresh ground at another lot. I was digging lots of clad coins, memorial pennies, and maybe one or two wheat pennies. Finally, the AT Pro corned a 1964 Rosie by the backyard gate and driveway. It sounded sweet and there was no mistake about there being silver hiding under the dirt. I decided to take a break and eat a sandwich. While I was eating I got to thinking
, I already have 2 silver coins with 2 different detectors and it's still early. It should be a snap for me to find a 3rd silver coin with the F75SE. I loaded up and headed to the corner lot where I found all those wheat pennies and silver coins. I swung and swung for nearly 3 hours and found nothing but a couple of wheat pennies and maybe a clad coin or two. I needed to change tactics. I've only hunted the F75SE in the 'boost' mode on that particular lot. I decided to switch over to the faster 'DE' mode for better separation. I cranked up the sensitivity to 85 and there was no EMI issue at all. I started getting more good targets. Each time that I dug a coin, I'd check around the hole in the all metal mode. I discovered that a lot of the coins had been masked when I was using the slower but deeper 'boost' mode. I was wearing down from digging and swinging so much, but I pushed on. FINALLY, I got a sweet high tone and popped a 1941 Mercury Dime. Yep, there was iron adjacent to the hole. I'm going to go over that whole yard again in the 'DE' mode. Oh yeah, I found a 1917 wheat penny and it came out the ground clean as a whistle. The other 6 wheat pennies ranged in date from 1941 to 1956.
