NULLING OUT

[Grizzly13]

The concern is nulling on a very discriminating pattern. I have customised my patterns for different sites, but I'm fairly certain that the nulling doesn't effect the good strong signals. Am I off base with this? Please help us on the accuracy of my statement.

That depends on the target(s) and it's location and size.

If the target (iron) thats nulling out is on top of a good target (say silver), the detector will not see the good target (silver) no matter what, you got to dig the bad (nulling) target up first.

Another thought is even if you have no discrimination and an iron (or any other non desirable target) is masking a good target you will probably only hear the iron target anyway. I think if you could hear, lets say a dime partially masked by iron with no discrimination you would still be able to hear it with iron disc out. That has been my eperience anyway. But I would agree that the nulling doesn't effect the good strong signals.

I feel that in very, very heavy iron sites, like field sites where iron is so abundant that even in relic mode you are nulling out, that with any disc at all and you will miss good targets UNLESS you are moving super duper slow. When I encounter a site like this this I flip my quickmask open and hunt with 100% open screen and good targets hit way better when using TTF.

In a field there is a thing called the iron patch, and this is the spot right where the house was tore down, when I go thru this area I slow down and open my screen completely and able to pick out targets super easy in TTF, when I get to the edges of where the house was tore down and the iron is lessening up, I hit my quick mask button again to go back to my relic screen.

I know for a fact that nails laying on top of a coin or even ones super close in a field will cause you to miss some of them unless you hit them at the right angle. But when you have an open screen there is no delay from nulling over the iron and it is much easier to get the good stuff. I hunt a LOT of fields and have experienced with this for 3 yrs now, and feel pretty confident in what I am saying here.

Now as far as yard hunting farm houses etc....this yr I have played around with opening my screen up more and I have found a lot more deep coins, coins on edge and coins with nails in the hole with them. I have had solid from all direction signals that were 25-35 and they were deep indians with nails in the hole. I have had a few silver dimes hitting at 50 CO as well.

I believe fully 100% that the more open your screen the more stuff you will get, perfect signals are rare, VERY rare at the old homesteads I hunt. Virgin properties are almost non existent anymore, so all the easy to get stuff is usually gone. A more open screen will help you get more of the stuff other hunters have missed. I have tried a lot of patterns and I have compared patterns with a lot of friends who hunt with etracs, they all have reported to me that by opening their screen up they started getting more deeper coins and partially masked coins. I am not blowing smoke, I am basing this on hundreds of hours at old homesites

Excellant post, Goes4ever!

I like to use my 8'' Sunray coil at sites with more nulling or iron than usual. It seems to pick the coins out of trash and iron better with high disc. JMHO.

Great post G4E...I am just getting into old school and farm sites here in Minnesota after discovering the Historic Maps website. I live at the end of a dead end road out in the country and just discovered a week ago from a 1895 map that there used to be a school house on my own road. It was just as you explained it would be. Only one good signal out of the 7 wheats and 1 toasted injun I found !

Yeah I had a site that in a 10x20 foot area I never heard my threshold at all using a 6" Excelarator coil and I went back with another brand detector that has a faster recovery and started pulling wheaties up! There is spots where the Etrac has it's cons but overall I use my Etrac 90% of the time I just seem to have better luck with it.

Hey Terry, good post. How far down do you have you pattern opened up too?

Hey Terry, good post. How far down do you have you pattern opened up too?

if your asking about my screen when I am in conductive sounds? I have it open to 27 line

TTF is the way to go in the iron infested sites.Once you get used to the constent iron signals then you will do well. Much deeper in TTF also.
