I'm a new Excalibur user, just got the unit 3 weeks ago... Got an question for other Excalibur users... seems when I have the coil underwater and sweep fast, sometimes a false signal will sound. If I tweak the sensitivity levels, it tends to lessen. Is this normal for the excalibur? Plus, seems that I have to keep tweaking the sentivity levels every few minutes to keep the unit from talking too much... Is this normal as well? I'm hunting on beaches in South Florida, from Delray to Deerfield, sand is all about the same on these beaches.

She'll false under ten but above nine o'clock especially if the bottom is uneven or if you bump a stone. Sounds like you're running the Excal a little too hot. You have to strike a balance between max sensitivity and falsing.

When using Excalibur turn your sensitivity up until it starts falsing then turn it down to the point where they have just stopped.When you are in the water concentrate on slow steady swings keeping your coil at a constant height off of the bottom.If you raise your coil at the end of your sweep you will get a false signal.Run it in Discrimination mode but with it turned down to minimum setting, threshold so you can just hear it, Volume flat out. Dig all signals, small gold items eg chains and thin rings will give very low tones and are easily discriminated out this is why I say turn your discrimination down to minimum setting.You will get more depth running the machine in this setting than you will in all metal(pinpoint setting). good luck hope you find plenty, seeya Neilo

You will get MAXIMUM depth running in all-metal/pinpoint as opposed to DISC.
Some hunters run it in all metal and after detecting a possible target, switch to disc to determine if it's iron or not. If in disc, and you don't get anything, then its prolly really deep and can't be id'd, so it would be worth to check it out to see.
If you run only in DISC, then that's okay too. It always depends on the hunter, on the particular day and what they are looking for.

Some say all metal is more sensitive, while others say disc is more sensitive.......
I have found that it depends on the exact location where you are sweeping the coil, which mode you are in, what sensitivity setting you use, and which coil you are using.
The only way to be sure is to experiment . Even then, you only know the best way to work that particular spot.

I run my sens. at between 11 and 12 o`clock on the waters edge, but you will find that in the water(surf) you are actually flexing (bending) the coil alittle and that gives you a false signal. In the water & waves I`ll run my sens. at 12 to 1 o`clock and have very little falsing.If completely out of the water I can run between 10 and 11. That`s me at my beach, but as said trail and error at your beach will get you the best setting for you. This my give you a starting point. Good Luck

but its hard to tell in waves and sand. I use a 12 in deep scoop and have buried it a few times.I used a sovereign for awhile with a 12 coil and it went 14 in. for a quarter with the same settings.At these depths the signal is weak or even broken and I may have to switch to all/metal to pin point it.In my adventures all/metal gives me maybe an extra inch of depth. A 12in deep target in the surf can take awhile to recover. My excal has a 10 in. coil and I have good finds with out digging to china. For me digging in the surf is tough, I go at night which makes recovery even harder sometimes.

These may seem unorthodox for some, but they work for me. My surf is highly mineralized, so these are necessary for depth and stability with the unit. I run in Pinpoint and when I get a signal then I switch over to Disc for a quick ferrous check. If I get a null, then I move on. I run the threshold at a little above audible. Volume is wide open. Sensitivity can be run clicked just out of Auto. This will be at around 8 on the dial, but make sure the unit is NOT clicked in Auto. Discrimination is always set on 1. These settings allow you to run maximum Sensitivity (for depth) and have rock solid stability, without sacrificiing your ability to check for iron. Try it, be open minded and stay with it and you will see the results. GH
Many say they get better depth in all metal, but on every test I have done here on actual targets in the ground the disc seem to get better depth for me. I have got several signal in disc that are weak and just a change in the threshold in disc. Now when I go to all metal pinpoint I don't get any signal at all or one that is weaker then it is in disc. Now maybe in some grounds all metal may get deeper, but around here it sure don't. I find it much easier to hunt too in disc in the park, ballfields and school we do. Like I say maybe in some area it may go deeper in all metal.
I have done a lot of trials over the years of using the Excalibur and I stick with what I claim about th e discrimination mode going deeper than all metal.As Rick Nd stated he has had targets that can be heard in discrim but not in all metal and I have found the same repeatedly.
I remember reading a feild test that was carried out by a minelab expert and it was also pointed out by him .

I feel that you and Rick are correct in your findings. What I am wondering is --- that Gulf Hunter said he could run at almost max sensitivity and remain stable in salt water. If that is correct, you can run at a much higher sensitivity in all metal; then both ideas may be correct. I don't really know; just wondering. John R
I use the Sovereign which is the same as the Excalibur, but not waterproof. I have a few that do some beaches in the lakes in MN which are within 50-100 miles away that use the Excalibur and really love them for water hunting, in fact one guy has 2 of them. One Excalibur has the 8 inch coil and the other 10 inch coil so he is prepared for what ever condition he is in plus always has one to use in case he has a problem which he has not in the 2 years he had them other than one had the knob come lose.

those dad blamed knobs on the Excal aren't designed to be switched back and forth so often, so you end up wearing out a pinpoint knob way too soon. I know because I did it on my first Excal and then on my Elite. I know this will result in some telling me it works fine for them, but you have to ask yourself, do you feel lucky??

Bare in mind that these settings are only really good in mineralized salt surf. We have black sand content in Galveston surf and to get the greatest depth with best sensitivity is why I run this way. In fresh water (lakes which are all trashy from what I've seen) and extremely trashy surf areas, then I run in Disc and just run the Sensitivity as close to 9-11 where the unit is stable.
It's Sunday and I just got back from the beach... Seems like everything was working well for about an hour... sens was roughly at 11:00... then I decided to hit the water line, had to spin the sens. to about 2:00 to get it from stop talking, it was still falsing on every other swing in wet REALLY sand... at first thought it was my batteries going down, to I got ready to pack up and walk up the beach, then I got a good signal in dry sand... Seems like the machine is fine in the dry sand areas, I can find some really deep coins. But get it in and around the water it falses no matter how much I turn down the sensitive... I haven't taken gone pass 2:00, but I wouldn't think I should have to, otherwise, I'm not going to pick up any thing except topside coins.
Any opinions out there on this issue? Should I have to go to 3 or 4:00?

If that is what it is, only a PI machine is going to punch through that much interference. You'll know when your battery is dying because the sound is unmistakeable WWHAAAOOO! WWHAAOOO!, then you've got 3 to 5 minutes till nothing but buzzing.
Were the waves really rough? or the bottom full of obstructions? Bouncing around the bottom will give falsing as well because the machine is trying to compensate for the ground balance. Maintain a constant distance from the bottom, if possible 1 inch or less and try not to bounce of obstructions as it will cause your Excal to false. Also try to maintain a steady swing that is fairly slow as swiping the coil around too fast will often cause falsing at the edge of the sweep.
Try your Excal on another beach that doesn't have black sand and see if it still happens.
I'm sure more experienced Excal users will be able to help as well.
Good Luck,

Yes, the waves were really rough this morning...Northeaster storm coming.. 2-4 foot waves... that's why I tried to stay away from the water's edge... didn't feel like fighting the waves on each good signal...
As for black sand, I really don't know... seemed like the south side for the first hour was fine. I was in wet sand, just a foot away from the water's edge... then I made it back to where I started.. and headed North, and within 5 minutes, I really had to start tweaking the sensitive back. Kept on tweaking more and more, and it was still falsing... That's when I thought it could be the batteries going...
So maybe your right, maybe the North side of this beach is really bad, as the South side wasn't falsing much at all, now that I'm thinking about it... It was really stable on the South side... How can you tell if there's Black sand?
