Silent threshold

[silversniper]

Hello. I am very new to the Minelab Explorer with just 1/2 season under my belt. When hunting my threshold is almost always nulled out on any site I visit unless I hold the detector still. Does that mean I am running too high of sensitivity or that I am experiencing a lot of trash, or both? What would you recommend?

Certain places I hunt do the same thing to my SE Pro. If there is a lot of iron in the ground it will "null out" like you described. You can back off the sensitivity or try running it in auto sensitivity. Also a smaller coil may help. I'm sure others will have more valuable info on this and may help us both.

As mentioned, also you could try Iron mask, screen wide open, it won't null and you will hear all the iron(low growl) and be able to pick up some of the non iron targets in amongst it, savage amusement at times but it works, also you could try a smaller coil in that zone

Great advice . Also when hitting a null , pull just away from the nulling until you get your treshold sound back and then SLOWLY try going over the null from all directions a few times sometimes it will help you pick out a hidden signal .

With every null your coil experiences some desensitivity. When that happens you loose depth which means you may miss targets. Reduce your IM to say 28 and move your coil slower... also try using manual sensitivity at 24. I think you will be surprised how much this might improve your nulling. Otherwise just raise your coil and your threshold should return. A lot of the good hunters feel auto sensitivty is the key and dont believe the null precludes their hitting good targets.

Just a thought on the constant nulling.
First I would find a clean spot and do (noise cancel) let the exp find the quietest channel for the site.
Then if it still was a constant null, set the gain about (6) and then try lowering the sensativity by (1or2 numbers) at a time until the machine settled down.
Personally I use gain 6 and sensativity 26auto. But have also had to go as low as 12 manual on sensativity.
These are just My personal thoughts and methods.
Nothing is set in stone and what ever works is good for me.
