Excal Setup...reading the signs

[Daniel Tn]

Okay let's see if I have this right. The Excalibur will tell you when the settings aren't matching the conditions? Say I'm in an area with clean ground and no targets under the coil...if the threshold nulls continuously while sweeping the coil it means something is set wrong. Is that correct so far? So if that is the case, I noticed when I lowered my sensitivity I started to be able to keep a s. teady threshold without nulling. Now my sensitivity is considerably low to achieve this. I think the actual number is 4-5 to keep the threshold steady. Is that how you guys read the language of each particular site? Just adjust the threshold to a steady buzz then adjust sensitivity to keep it steady and not null over the ground itself?

when u r over black sand on the beach it will null but i found that even with that null when i go over a coin under the black sand it will give me a signal,,,i run my excal at sens 6-7-8

I agree with what tomcat said completely. People seem to worry about "the null" a lot but I have tested the "handicap" of finding a target through the null and I have to say that there really is not noticeable loss for me when my machine nulls. I have tested infinite scenarios where a good target was "in a null" due to another target, where the good one came through. Certain locations I go to cause my machine to null out almost the entire time, just make sure your volume is set high enough for targets to "scream" through and you won't have a problem. I am sure someone on here will disagree with me about "losing targets in a null," but as far as I can see, you will never lose a good target through nulling, but that's just my experience. I also regularly have to hunt with my sens set to "4-5," so I would say that is normal. I hope this helped and if you have any other questions, feel free to ask. HH -Marc

So what are you using to determine your sensitivity setting? If it's not the nulling of the threshold that you are going by, then why not run it hotter than 4-5?

AUTO when you hunt the N. Georgia and Tenn. lake beaches because the sand is only 6 to 8 inches deep. Underneath that you have the highly mineralized red clay and hot rocks that will make your detector null or go silent. In the ocean stay out of AUTO and run the sensitivity as high as you can and still maintain stability. I have found that these setting work quite well
