I am having a hard time learning what part of the coil to use for Pinpointing with my F75 especially when I changed the settings on it so it would run more smoothly in a high trash environment. I got a tip from a tech at Kellyco to go into all metal and turn the threshold to -5 then go back to discrimination mode and run my sensitivity as high as possible as long as the detector stayed stable and not too noisy for detecting areas with lots of trash. I also saw where increasing the grab ground setting by +3 under manual ground would help with not missing small targets. After I changed these settings and went back to Discrimination Mode I was not able to pinpoint off of the toe part of the coil anymore. I instead seemed to have to use the part bottom part of the top 1/3 of the coil, which is the part of the coil that is the bottom part of the toe? Whenever I have pinpointed in the past before I made these setting changes, I was able to use the wiggle method and pull the toe back and my target would be consistently where I thought it ought to be located. I did not know changing the settings on the F75 would affect how to pinpoint?
Also whenever I have used the 5"DD coil I have yet to figure out what part of that coil needs to be used for pinpointing? On my Tesoro's I use the center of the coil as a reference point. The heel to toe method works well on my CTX as well as the center of the coil itself. I can usually use the X method with every other detector I have, but not the F75?
Any suggestions would be greatly appreciated.
Maybe the Threshold Change is not something I ought to do even though the detector runs much more smoothly and I am able to use as much sensitivity as I desired even all the way to 99.
