I get the "lift coil" pretty frequently. I have noticed that sometimes when I do, even an inch or two, I lose the signal altogether. There is no doubt that this is a sensitive machine. The old coins in this area take some work to get to and because of the high amount of trash the other detectorists in this area turn tail and run because it is just overwhelming and that leaves this mess all to me. I find that using headphones in this area is no fun because of the constant signals and often use the speaker. I have recovered a few coins from the turn of the century here. After mucho research this seemed like just the machine to use. In the clean area I tried, it rocked! I am going through the learning curve with TID and know it is going to take some time to use it accurately. I think that with a small coil I should have a coin hunter for sure. The disc on it does seem out of whack and it may get sent in for tuning. Unfortunately it is very cold here now and the ground is getting harder than chinese arithmetic. Cleaned and waxed my machines yesterday and am getting ready for some intensive air testing to try to get some settings, numbers, etc. put together for the next thaw. Until now my machines have been dual disc. and notch disc. which I have gotten comfortable with. In my limited time with the Deleon I find myself not watching the meter but listening for the audio and have to remind myself to watch! I frequently get good visual signals with no audio. Is this a problem with my machine? I have also noted that when either verifying or pinpointing a target the tuning seems awful slow and often erratic. I spent a few hours just reading the display without digging while trying to learn the best way to stabilize readings for accurate ID. I have the best success with sharp, slower swings of six inches or less. Anyway, it is bought and paid for so it will become a topnotch trash hunting coin buster! I am ordering a small coil as soon as I figure out which one to start with. The neat part of that is I am paying for it with the modern coins I found last fall. I hope to get that kind of performance from my Deleon also!
