I took my Tiger Shark out today and I have it set at the stock Gain, And It was falseing and thear was no Hi Line wires in sight and nothing that can cause RF , I had the coil at wast highth and it was still unstable ,
Can Hot ground cause this??? I was still in the water, Wen I got home in the House it dident do it???? HELP, Mickfin
 
HI Mick,
How long have you had the detector, were you in salt or fresh water? Have you checked for a dud cell or corrosion in the battery pack? Check the coil connector for no ingress of water. The Tiger Shark will not false over hot ground if the coil is at waist hight. The Tiger Shark can be noisy in salt water, it is a VLF machine and is better suited to fresh water. Did you have salt mode selected. Go back to the same location and try again, maybe there are underground elec cables.
If it falses in the same place again then move a couple of hundred yards left and right, forward an back and try again. Wind the sensitivity down to just above zero, if it is still falsing then you have probably got a cct fault.

Mick, was the control box on the shaft or on your belt...if you had it hip mounted you have to make sure the cable is as short as possible so it doesn't swing within about a meter of your coil...this can cause terrible falsing. All the best, Sapper.
 
Thank you Furious T I got the Tiger Shaft mounted and no swinging on the cable, N Thanks Adrian SS 4R your input,
All els is good how do I check a Coil connecton for water?????
Coze wen I got home it was dry an did no falsing, I thought about under ground wires , But I did walk on dry land and is still did the falsing, Thanks you 2 , Mic
 
HI Mick,
If the connector cannot be opened ( don't try unless you know how)then give it some heat from a hair dryer for a while to dry it out.
Some Tiger Sharks were prone to coil problems, you also need to know that no water has penetrated the control box.
But from what you have said it sounds like either there is a problem with the coil or water has got in to the coil plug or control box.
The Tiger Shark will false a bit in shallow salt water due to wave action over the coil.
In an area where there is no elec interference and the coil at least 3 feet of the ground the detector will not false unless there is a problem in the detector or coil..

Adrian SS I dont know how to check the Conn N Coil, But tell you what I can do is go to the spot and NOT going in the water N see if it falses 4R RF Ya or Nay then go in the Water ???? Thanks SS, Mic
 
Some Tigers will give a single false tone as the connector hits the water, so if you were standing in water that was right at the connector, each time it submersed or came out of the water it might make a single false noise. Most overcome this by paying attention to the water line and after dipping the connector portion into the water, slightly bend your knees so as to KEEP it under water. Wave action, if you are at the right highth, can cause what seems like repeatable chatter if the control box is in/out of the water with every wave.

Water action over the coil does not cause chatter. You might also check the coil cover, to be sure there is no sand in there. If any of it is magnetic it can cause your machine to chatter. You might also inspect the cable sheath over the entire lenght, looking for a slight cut or crack in the outer wire insulation. If you find one, you may have to epoxy it. If your machine works fine on land, then it has something to do with the water.

Scully I will Look at that water stuff for Falsing, Thanks , Mic
 
Scully is correct about that.

I had a Tiger Shark that I was using on Silver Beach in St Joseph, Michigan.
Every time the water would touch the coil connector it would false.
Only happened when I was about waist deep and the control box was dipping into the water as I worked it.
Tried a lot of things to get it to stop that ... but never was successful.
Finialy I hip mounted the control box which kept it underwater most of the time.

BTW: I did find some golden goodies there!
 
hiya micky,,,the chances are that yoiu were on the beach??? RIGHT,,my minelab was a bugger at doin that,,,what hapens is the machine is compensating for the water poaring out of the coil cover ,,,or the build up of sand or soil on the coil and trying to ground balance, or you where detecting over a U F O ??? what ive found is that if you use a clear silicone sealant which you can apply sparingly with you finger a little at a time, you will prevent an ingress of all sorts of stuff into you machines field of vision,, and it usually works,,,if it does not,,,,then buy a detector pro wader, they are cheaper and work as well, or better,,thats my experience,,, my tesoro cibola with a 12 x 10 d.d. coil, works as quiet and as well as a minelab g t ,, but they are not submersible,,, however if your not wadeing or diving then there must be more machines out there that can do the job in that environment?? but the TESORO CIBOLA with 12 x 10 d.d.coil is my favourite in all environments,,, check it out,,,rgds ,,comcat:ukflag:
