Excalibur Falsing Question

[scoutingbear]

I was out with my Excalibur yesterday and it started to false quiet a bit everytime I hit the wet sand and when crazy in the water. As soon as I moved to dry sand it seemed to get better. I checked all my settings and even tried different ones with no luck. I do not feel it is water related as it was happening in wet sand too.

I have been searching these beaches for a year now so I know the tones. This was different.

Any ideas on what to look for?

(Battery was fully charged, checked to make sure wire had not slipped down to coil, moved coil connections at both ends to make sure no cable problems. Settings were: Disc, Volumn all the way up, Sen (Auto and at 12) Disc at 0.)

Hey Bear.........

This is a possibility.....kind of like grasping at straws, but still a possibility.

The way my Sovs work, at some times and places I get a lot of falsing. This seems to be caused by a mixture of electrical interference and it's effect on ground mineral. Moisture also seems to have a part in it too. Sometimes it is mostly nulling, while other times it "talks" a lot. The ground seems to really light up with the noise.

I set the coil on the ground and turn sensitivity down to the point that it smooths out. That stops the electrical noise from falsing pretty well. Then I sweep the coil to see if I get nulling (in a clean spot, of course).........if so, I turn the sensitivity even lower to cut most of the nulling out.

Have been places where it's really severe to the point that nothing works good. Seems to change from day to day.

No good way to tell where the noise comes from, or anything about it's spectrum.

Best I can do for you.

Art,

This helps greatly. I had not seen falsing change like you indicated but as long as I know it does for others, then I can guess it is happening here too. I did a dry land test at my house and all seems to be working find so it must have something to do with changes at the beach.

It's a "time and place" kind of thing.

Don't know what your dirt or sand is like. Have clay dirt that runs from yellow to yellow-orange. Not much topsoil. Many places are fill dirt from basement excavation.....nasty clay. Got hot rocks left from the ice age glaciers.

Seems like any time noise is bad, the dirt and anything in it lights up and causes trouble.

Really like the quiet places with silt dirt or good topsoil and no trash........can run sens at max with any coil without a bit of noise or nulling.......if I really want to. Even then the Sovs get best depth and target response at 11-12 o"clock sensitivity. Ground noise that is still present (probably induced by the TX coil) will still limit "best" settings.

Have fun.

mine does the falsing also It seems to happen in certain areas if I move down the beach 5 or 10 feet it usually straightens out again. If I go back to that area it starts falsing again. Maybe it a crop circle thing at the beach

 

[scoutingbear]

OK, so we have beach circles now. Sounds right to me. Need to do some internet research on them now.

My excalibur 800 chatters in 1 foot of water but it goes away at 2 feet. I figure at only 1 foot, the detector/coil is overworked dealing with the ground minerals in addition to the varying waves. This is freshwater - if you are in saltwater it might be worse. But just a little deeper, the wave effect goes away. Some days are worst than others. Perhaps the water is silted up with minerals, or electrical interference is bad.

Perhaps the same thing can happen at the waters edge. Black sand gets laid down in a such as pattern that the detector cant adapt to the ground minerals fast enough.

Some days when the there is a threat of thunderstorms (not actual thunderstorms occurring, I don't hunt when lightning is flashing!), my detectors get even more unstable.

They get most unstable when I get a loop of fishing line with a sinker or swivel attached and I don't notice it for several minutes. That really drives me crazy!

 

[scoutingbear]

All,

This is all good information. Seems that others have this come and go and maybe it is not the detector so much as the conditions. With any luck I will have my second detector by Sat. and I can start checking things out.

Thanks for the help.

First, thanks to all that replied. I got to go out early this morning for the first time to try some of the suggestions. It seems that for whatever reason, I needed to kick the sens. back a bit and falsing went away.

Glad to say the machine worked well and found me three rings, 1 nitro, 1 mood, and one 14K white gold man's band with stones.

My hunting buddy is so fed up with me finding rings during our outings and him getting skunked that I think an Excalibur 1000 may be on his arm soon. I let him try mine and see the different. He had a Fisher (I forgot the model). We hunted close, when one got a target the other was called over to see if they could hear it with their detector. After him hearing three targets on my machine that his would not pick up, he had had enough.

Keep something in mind, Bear.............

Be careful about hunting close to each other. You may not notice any interference between detectors, but it is there anyway. The more noise the detector has to digest, the more difficult it is to pick up weak objects.

You might try something.......

Keep a good distance apart. When you get a really weak hit, ask him to come over. See if you lose the target when he comes within a particular distance.

Hey Bear, Are you hunting in Auto Mode Sensitivity with your Excal? If not, then switch to Auto, and the falsing should settle down quite a bit. HH,
