constant stream of tones in im-16

[Anonymous]

i am trying to hunt in im-16 around old homested foundations with the ten inch coil. there seems to be a almost stream of high tones several a second, and the cross hairs are almost always stuck high and to the left.i can tell tone changes but it takes a second for the cross hairs to catch up. i am running my gain at 8 sense 27-28 auto. any advice or is this how its supose to be??

Here are a couple of situations where that will happen. If you are up close to a foundation that has iron in the foundation construction.
If the coil is not in motion and this is what you get for the entire area then it can be noise from EMI or if searcing with another Explorer user. Noise cancel in a clear area to be sure and kill the noise if that is the case. <span style="background-color:#ffff00;">See what happens if you go to IM-15 or -14. If it nulls then then it is iron</span>. Using IM-16 where we get hits on all metal can be amazing when it comes to how much there is around an old building.
I have searched around old foundation where it could not be done in all metal with any of the detectors I tried. There was just so much trash iron and other metals there was no way. There have been some I had to walk away from and never could search them.

If you must hunt in -16 then you better use ferrous sounds or every piece of iron is going to high tone... better off running -15 as it will knock out the majority of iron hits while still allowing good targets to come thorugh as long as your sweeping slowly in the nulls. At any rate if hunting in high iron I recommend using ferrous tones no matter what your settings, but some people do prefer conductive, personally I dig everything that reads above iron, so in ferrous I can immediately tell positive signals from iron..

for the most part. If his suggestion doesn't do the trick by itself, try sticking with ferrous tones as he mentioned but continue with IM -16. With -16 you might want to try adjusting down just a tad for your sensitivity setting to hopefully reduce masking effect, say something in the low 20's. You're probably dealing with nails from the original structure. With -16 ferrous you'll hear a tone instead of a null which will help prompt you how slow to sweep in order to get the good stuff mixed in the iron. A smaller coil should help if you can get your hands on one. Good luck finding the goodies!
