I have a problem, I think, with the mod I made to my Excal and the WOT coil...

I installed the waterproof connectors to change coils so I could use my WOT and the regular coil. But, when I use the WOT in the water it falses all over the place. The threshold goes up and down constantly. On dry sand, it is fine. The regular coil works as it should in water and out. So any ideas as to what is wrong? I'm thinking it's too sensitive, but when I lower the sensitivity it still does it.
 
check your battery connection for water getting into plug?? but id have to ask does this only happen with the wot only?
 
which excal do you have? Where do you hunt, and is excal submerged..........................so the stock is fine, and used in the same conditions as the wot? And this wot coil is New?
 
at which point does the machine begin to false? you need to isolate the problem.
1. coil only submerged?
2. coil and new connectors submerged?
3. coil, new connectors and control pod submerged?
4. was your excal a 5 wire model or a 4 wire?
as which part enters the water does the unit begin to false?
i had this problem after installing a sef coil and i first suspected the splice, it was not the splice!!
chuck.
 
It begins to false as soon and the WOT hits the water. It doesn't matter if the pod is submerged or not. so as far as I can tell it's not the connectors. And I have the 4 wire model. As I said before it works great in the dry sand but as soon and that coil hits the water the threshold goes nuts. I even tried turning down the threshold down to silent running and it still made noises
 
humm id say water is getting inside of coil somehow,check it over really good, if its a new one id try to send it back if possible..
 
I would say the WOT coil is just too big of a coil to use in saltwater with that detector.

The amount of area the coil is energizing is overloading the detector ... saltwater is conductive and the detector is seeing it as a target.
Increasing the discrimination might help some ... then again it might not.
I experienced the same thing with a WOT coil on an Explorer II ... great on the beach ... so so in the wet sand ... lousy in the saltwater.

Clive Clynick says the same thing in his new book on the Minelab Excalibur.

Not to highjack the thread but, has anyone tried the SEF coils 10x12 or 12x15 on an Excal? I hear they are more stable than a WOT.

Maybe so. But why then does the large SEF coils not have a problem? And why is it that so many are running the WOT in the water and no problems at all?

I think it may be just his detector specific. Something is wrong and it may be just a simple thing. Not saying you are wrong, but I ran a WOT on my older Excalibur and it was not a problem at all. The WOT is not a problem with the Excaliburs I've owned.

I have seen many WOT coils on the newer Excalibur II's in the water, on the beaches and on land and have not heard of any problems at all.

The one question I have not seen asked is.......are you running a coil cover? If so, get rid of it.....it collects sand and water and causes all kinds of trouble. The coil covers will cause all kinds of falsing. Coat it with some pickup truck bed coating and get rid of that cover. I can say I did run into that with the cover and it went away after tossing it.
 
have you tried auto sens to see if that calms it down? it will react like that if the sens is to high for that area.
 
Have you tried it in fresh water, like a river or lake?

I had a problem similar a year ago, as soon as the excal would hit the water, 10 inch coil, it would start going crazy, come to find out if you looked at the coil wire in the sunlight and pinched it in a U shape there were small cracks from the rubber dryrotting, replaced the coil & wire, all is fine. ..If it is a new coil, send it back, and if the refuse and you put it on your credit card you can "resend" the charge by calling the credit card company. Think you have like 60 days to do that, but call. If it is used, may want to contact the person you purchased it from. Good Luck....joe


In fresh water mine was fine, but as soon as I hit the saltwater, it would freak.

Some of the SEF coils do have a problem, I sold one off for this reason. I have two left, a 10X12 for my Etrac which works great and just got a 10X12 for my Sov that so far Ive only used on a freshwater beach.
Good point about the coil cover, that could do it also.
 
I use a WOT and havent had any problem as he has described so its not just because its too big a coil for the salt water. There is another reason. Some coils just do not like salt water...and it can be specific to that coil, not the whole model series. Example, I was on the beach this afternoon with my Xterra 705. Never used it on a salt beach. Fresh water no problems. Was using my 8 inch medium freq coil. Had no problems on the dry sand. hit wet sand and it didnt like it. Falsing bad..dialed down the sensitivity, regrounded, made sure it was in beach mode and was just ok...put it in the water and it would freak out. Go back to dry sand and would work great...go to wet sand...and it was just ok...but go to water...watch out. Sounds just like your coil. So am going to check with minelab and see if there is anything specific they can tell me. Sandnsea, you know where my location is up here in the panhandle. White sand beaches, not heavy mineralization really. Just the salt.
 
just too sensitive for the salt water. It picks up very tiny pieces of foil and such so maybe that's the problem. I still have to figure out if it's leaking. It's not like a tire and I can put it in water and look for bubbles so i will try some of your suggestions. If no leaks, I use it for the dry and put the 10" on for the water. Thanks guys.
