Do you dig a break in the threshold in discriminate?

[beachdude]

Just wondering if you guys dig a break in the threshold while set in discriminate?

A break in the threshold sounds like a null of iron or a disc out target, a good target will repeat for most part and one I would circle the target to see if it is a repeatable one or not. Anytime I get a slight high tone threshold I will work it from different angle to see if it will repeat and try climbing in tones and meter reading. A break in the threshold where it nulls would be a disc out target or iron, so I probably wouldn't dig unless there was a repeatable signal in with the break of the threshold and it would have to be repeatable too.

Switch to PP and check it. Can't hear it? Then it was nulling from ground minerals and not an actual target. If PP does see something, does it sound deep enough that disc would null out something good in *that* soil or sand (which depends on the minerals)? Then dig it. If it sounds shallow enough that it shouldn't null in disc on you and yet it does, yet PP says "it ain't all that deep", then only dig it if it's deep enough that those minerals might be choking out a non-ferrous target like a coin or a ring. If it sound shallow enough that disc should have no issues with it yet it's nulling it then it's iron. The depth where nulling in disc happens depends on the minerals. At one bad beach I hunt even coins at only around 5" are nulling out sometimes, and I would have completely missed them had I not been hunting in PP mode.

On any machine, when the target gets to the extreme outer range of the detection field, the microscopic iron in the soil starts to become stronger than the now too weak target signal, so the target starts sagging in conductivity down to the iron range. Thus the null on the Sovereign, or on other machines even using no discrimination the target is ID'ed as a small piece of iron.

i do like rick mentioned.....work that null from every angle and varying sweep speed.....ive had some good targets null once or twice until angle of sweep or speed of sweep were changed.....if at the beach just kick an inch or two of sand off it to see if signal improves,if not i move on to the next potential target.....

Seeing your name is beach dude I'll assume you do some hunting on the beaches. With the GT and Excalibur and beach hunting many many good targets are not more than a chip in one direction. It becomes second nature to dig targets once you get some time under your belt with these two machines.The best way to learn is to dig. The easiest way to learn it to guess your target via sound and signal. Not some but everyone you hear. Then you'll be better able to walk on target that could result in trash. Can't tell ya how many nasty pennies I dig knowing there all pennies till I dig a gold ring that sounded like that penny. Has happen far too often not to dig them. Just one of them paid from the GT twice over! The beach is just too darn easy not to dig very signal, unless time becomes a factor! On a side note there isn't reason in the world for a coin to sink on the beach flat. all coins are on some edge to any degree.That is till it hits some hard pan this is normally way out of reach for most hunters. By this time the coin is nearing the limits of detection and is not more than a faint tone, that only proper coil control and discipline will fine.Rings on the other hand have that nice hole to help them sink flatter.

I have only had an Excal for a few weeks now and I am doing pretty well with it, but there is one area in a site I am hunting that is just a nightmare to hunt. Chirps, nulls, everywhere. The rest of the lakebed is more manageable, but this area is full of false targets but also some good ones... It seems to be mostly iron nails and bits of tin and copper boot nails and other random metal. I have learned that by digging a lot of the signals to see what they were. I turned the sensitivity way down and it barely helped so put it in auto over this area and that was a bit better. I dug a 10k wedding band out of there and some silver coins so I know there are good targets, it is just that it is so busy. If I hear something that sounds even partially good, I take a scoop of sand off it to see if the signal improves. If not, I move on.

a real deep target can cause a blank in disc and you might not get a response in pinpoint. if youve got the time it might be a good idea to dig some of those signals, on a beach the digging is usually not to hard.

I did anything to gives me a conductive tone, click, crackle, pop, and have been very very pleased with the finds that were there. When the targets were out of the ground the holes nulled. That is on the beach btw.
