WOT on Excal II help

Can anyone who runs this set-up message me or e-mail me caymanchris@gmail.com. I have just recently put a WOT on my excal II. I hardwired it, I have no leaks and it works....to start off. After about 2 hours after hunting, the unit became more and more unstable. I could not even turn the threshold down any lower without turning it off and it was still louder than I ever run. It was not like this at first though. I was about 12 o'clock on threshold and running quiet and smooth, then it keep having to be turned down more and more until I was turning the unit off to quiet down the threshold. It seemed to be very unstable in the water also. I did have to reverse two wires when hooking it up to the Excal II, but I am sure this was correct because the wires hooked up the way said would not give a threshold sound at all, and this is what the guy from Coiltek said. Any help or advice would be great.

Thanks,
Chris
 
That is how I have it wired. That is why I am a little baffled as to why it seems to be "unstable". I tried all different settings, thinking that it is a larger coil and expected I may have to turn down sensitivity, volume and maybe turn disc up a bit. However I could never REALLY get it to where I felt it was working properly....In the water, out of the ater it seemed fine. BUT at the end of a couple hours and I could not get the threshold to quite down without turning it off, I got out of the water and messed with it on dry land and the threshold was still loud at the lowest setting. This probably is not making any sense to anyone, because it really doesn't make any sense to me either. I would think that it being wired correctly and was tunable to start off, that all is good and that with small adjustments it would work well "IN" water as well. There has to be some reason that my threshold sound continuously gets louder and louder, hence me having to keep turning the threshold down lower and lower until i can't go any lower but to turn the unit off.

Have you tried a different location, as Larger coils draw more EMI noise.
 
It sounds like you may have gotten water in the coil or cable.

:thumbup: I agree,


throw the 10 inch back on and see if you have the same problem.....

I think that maybe this is the problem.
 
Thanks to all who have responded. I think you guys are right. When I hardwired the coil into the Excal, I must not have had it sealed 100%.

Will Minelab put the WOT on my Excal if I send it to them? I really don't want to take the chance of my unit leaking.

I don't think so. Call or email them and see what they say, takes a day or two but they usually reply to all emails. HH -Joe
 
No, Minelab will not put the WOT coil on. They no longer do that or install any other Minelab products. It is easy to do yourself.

Your best bet is to use small shrink tube on the wires and then one larger shrink tube around all the other 4. Then use liquid tape or other sealant on the ends of the tubes. Then, using waterproof electrical tape, tape it all and you will not have any problems.

Your main problem right now is to get the water out of the wire. Hand it upside down and allow the water to drain out.

Nope, they will not do any custom work.
I really dont know anyone that does that anymore.
Just too much risk I guess.
I have some waterproof coil connectors that I intended to put on my Excalibur II but decided otherwise after reading a more about it.
Even the people that sell the connectors and do other repair work will not install them.
The waterproof connector requires a lot of maintenance to avoid failure.

My two cents:
Most people that have tried the WOT on the Excalibur have found it really does not work as well as they thought it would.
Only reason I can think to do it would be for very deep targets in the saltwater (otherwise a Sovereign GT would do as well).
Needs an area that is fairly well cleaned out of trash as the thing will overload with too many targets under its coil.
Put a WOT on a Sovereign and you will see what I am talking about.
If that was what I were looking for (very deep targets in a well hunted, cleaned out area) I think I would rather use a White's Dual Field PI or some other deep detecting PI like the Garrett Infinium LS with a large coil.

I respectfully disagree. Most people I know say the WOT is great. Maybe we should have a poll for those who own an Excalibur and a WOT. I know several people with the WOT on their Sovereign and they love it. They are the reason why I got the WOT for the Excalibur.

I installed the WOT coil for two reasons....coverage and depth. I got both. The 10 inch factory coil is OK but the coverage of the WOT is outstanding. I also notice more depth over the 10 inch factory coil depending on the conditions. If there is a lot of trash, then the WOT is not the best choice. But for dry sand, and in the water, the WOT is great. The WOT pin points great too.

In Salt Water, depth is not something to worry about as digging really deep in neck deep water is not fun. Most of the rings and bling I have found in 20 years of salt water detecting have been in three scoops or less. I would say 14 inches depth or less. If I was to dig any deeper, I would need a back hoe. OK...I may have missed some of the deeper targets.....but those are for another day. Beaches change every day. Targets move more on them than anywhere else.

I guess it is the old Ford vs Chevy argument. Some like, some don't. As long as what you are using works,,,,,,that is all that matters.

Yeah PI is a great way to go.....for some. Not always the best though.
 
Me too I had a WOT on a Excal and it was great, wish that I had not sold it. Using a PI now, which is better sometimes and not as heavy..
 
Thank you for all your help. The diagram came in very handy! Got it all going>>>>SWEET. Man that WOT is bad@$$. Don't regret doing this mod at all. Now all it has to do is follow my lead and find some gold!

Thanks again to all,
Chris
