coil question

[bruce01364]

Doing an air test with a coin I get a signal on all parts of the coil. Even the spokes going from the middle to the outside. This causes a problem in trashy areas as I get too many signals. I can't tell if the target is under the center of the coil or the outside of the coil. Sometimes I can sneak up on the target from different angles and figure it out but other times the targets are too close together to seperate. Does anyone know how to solve this problem?

Bruce try both lowering your sensitivity and using a smaller coil if there are that many targets where your hunting. go even as low as single digits on the sens and see how that works for you.

I was detecting in my moms yard yesterday, her house was built pre 1900 and been in my family not to long after that... As you can imagine after a hundred years worth of remodels and gardens the yard is very trashy. I was using the stock coil yesterday, I lowered the sensitivy a bit and switched to 4 tones instead of multi and high trash and it made it much better. I am sure I passed over a lot of stuff but i was getting a tone every 6" literally. I dug up some of grandpa's old car parts Wish he would of burried some silver around here for his grandkids to dig up!

Try using a smaller coil. Put the setting on fast and not deep. And try to discriminate out some of the most common trash items in that area.

You must be refering to shallow targets in which case you can lower sens. and or raise the coil a bit for better seperation .

Thanks for all the tips. I will try them. Have a 8x6 coil ordered.

set the machine to the relic pattern. Set it to frrous sounds and 2 tones. You will then hear most of the iron and all the non ferrous targets. Use auto sens, I cna usually go with auto+3 but you can lower it to auto and still get good depth. Fast on Deep on. Difficult gorund High trash. Digital screen. When you hear the higher tone, (of the two tones) stop and check it out. In bad ground or a lot of trash you may not get a repeatable signal when you turn 90 degrees and check it. The ferrous number can range from 4 to 25, give or take.... but the conductive number will be right on or very close even at depth. Once you learn the conductive numbers that are almost always bad in that site dig the good ones. Around here a minnie is almost always 33/34 sometimes a little higher. 46/47 is almost always a quarter unless the ferrous number is 30+. Steel washers fool me and other circular iron like an old bearing will read and sound good. Small cut square nails sometimes have to be dug too.

That is the way I almost always use the E-TRAC and I find lots of stuff where other people don't. The ET is great in "hunted out" places if you set it like that. The Pro coil will tell you when there is a non-ferrous target in trash. You will usually be able to "wiggle" in a good number from at least one direction. When you pinpoint it may give you an iron reading because of the trash in the hole it will then read.

The iffy signals are what you want, especially in trashy places that have been hunted.

Another thing you can do is grid off a 10x10 or 10x 20 area and dig everything. Start with all the strong signals and big signals. Finally run it with quickmask wide open but by that time the ET should have found every non-ferrous target.
