For the last few months I've been usining my new NEL coil for my F-75 with pretty awesome results and went back to a spot today that skunked me a few weeks ago. After chatting with a few members here, I thought maybe since there is a ton of iron at this spot, the good targets are getting masked. After having a hard time getting any signals today, I switched back to the smaller stock coil. The grass was up 6" or so, which usually isn't a problem with my machine in Boost mode. The grass was also a bit wet. Now I didn't have any "chatty" problems with the NEL today, but with the stock coil, the machine wouldn't quiet down for anything. If I stood still, the machine didn't chatter, but when I started moving and brushing it throigh the grass, I couldn't hear any solid hits, only chatter. The ground isn't hot, theres no EMI, so what gives? When I moved out of the tall grass, the machine was fine and I ended up with a few keepers for the day. I've never had a problem with grass. Anybody have any ideas or feedback? Thanks,
