A New Tip I Think

[kzoomn]

Don't coil the cable from the control box down to the search coil. Instead, tape the cable in a single line up the shaft to a point above the collapsible joint. Start the coil from there. As you swing the coil from side to side, a loose cable coiled around the shaft, and near the search coil, can give false signals

This the first time I heard of this, have any of you found this info to be valid?

 

[woodwizard]

ya definitely don't want the cable flopping around-I install additional coils on lower leg to make changing quicker and easier, I have the cable taped to leg then when installed to upper shaft I coil it the rest of the way till plug in -so I think its the same thing your saying

I've never heard of this causing false signals but it would be interesting to find out if it is true. May explain why sometimes get false signal and other times not getting them in the same conditions. You would think if it were true the detector manufacturers would not advise that we coil the cable all the way down the shaft.

I agree. I think you can wind it around the lower rod or attach it however you want ,just so long as it is not flopping around. It can definitly give some false signals.

Hey, I get so many false signals that a few more won't even show up on the radar.:angry:

Why is this?? Is it just certain areas? If my machine falses enough to get my attention I will put it all metal and see if there is something in the ground causing this. If not,, well,, something is wrong. Many things can cause this: Sensitivity too high, power lines, coil wire loose,batteries or the coil could be bad.

I have hunted a yard b4 where could hunt most of the yard with no problem. But one area the detector would start falsing badly, everytime I tried it there. Had to turn the sensitivity down , must have been more minerals ,in the dirt,in this section.Its all I could figure.(unless there was something very big,like a car, buried down deep)

I don't know why is it. I have encountered targets that were supposed to be 6" down and even after I removed a column of soil 12" in dia and 18" deep, the Elite still tells me that there is something 6" deep, I suppose, in the middle of thin air, when in fact there is not. I have gotten signals and then dug the target and the target vanishes. The original signal was a strong consistent "ping" each and every direction I swung the coil, but after I started digging, the signal vanished.

I have no idea why these things happen but they surely do.

A metal detector will detect a COIN SIZED TARGET with accuracy. A sewer or water pipe etc. will give a misleading signal. Unless that LARGE object is shallow then you should get an overload signal.

Unless you are in an area where you suspect that fill dirt has been brought in, I don't think there are many coins below 10 or 12".

Just my humble opinion, Dave

Well,,,hmmmm. That can be explained if it only happened every once in a while. And it seems you are saying it happens alot. Has me stumped if this is happening at different areas and on a consistant basis.

I have had signals as you say, but not often. Large object buried at just the right depth to fool the machine. Perfect coin reading, roll over the plug and dig 8" and it dissapeares.Bury it back and there it is again, perfect reading.I have always dug these things just to see what made them so special. Baseball size item at 15"-20",,,,,,but who's to say it couldn't be a car rim at 30+". Again,, what are the chances this is happening to you on a consistant basis??? NOT good.
Good Luck

I get the same results with my BH land ranger, I' stoped MD for serveral years because of that.Now I'm willing to try it again.I'D LIKE TO HEAR MORE ON THIS SUBJECT FROM OTHER BH OWNERS AND IF THERE IS ANY CURE .

When you wrap the cable around the bar, your creating a larger EMF that will give you false signals. I just bunch my cable up and put a rubber band around it up 3/4 the way up the shaft. That way it away from the coil, and not to close to the system board.

 

[GoGoGopher]

When you coil the wire around the shaft your creating an inductance...this can be helpful, or harmful depending on the value of that inductance...It can be helpful in eliminating some EMI (electro-magnetic interference). It can be harmful if the value is just right to throw off the circuits in the box...I do as one other user here has said...I put the cable in a straight line and tape it solid about 2 inches above the plastic on the bottom rod, then I wrap tight for about 5 turns, then loose, then tight again when I get close to the box...This seems to work for me, but may not for everyone...a loose cable could cause falsing if it is flopping over the coil...Afterall, it does contain copper and probably tin or aluminum on the shield (braid).
By tight I mean close spaced windings...


Happy Hunting,

Water hunters secure the cable straight up the shaft to reduce water drag.
Don't know if it really helps but I do it. Of course, before I heard about it I
wrapped the coil cable in the ordinary way. Not sure if it really made a big
difference or not. Just me 2 cents worth. Good hunting to you ! Gene

 

[drummerman]

I know when I first got my Time Ranger, I coiled the cable around the shaft all the way up so I didn't have any excess. Looked pretty. I figured the cable was shielded. But I was getting hits all over the place when I was hunting and was getting frustrated when nothing was there, or I couldn't seem to get an accurate hit. I had read somewhere not to coil the cable around the shaft, so I just bunched it up higher and put a rubber band around it to keep it neat. Made all the difference in the world for me. I got less false signals and it even seem to able to pinpoint the hit better.

 

[Gene]

Thanks for posting that Drummerman. Wouldn't think that would happen with
the Time Ranger. When I get mine I will definitely do as you have said.
I appreciate the tip and am glad I saw it. Good hunting to you ! Gene

 

[flash5153]

Wow, I have never heard of anyone having a problem with the cable being coiled around the shaft, unless it was loose. Don't the companies tell you to wrap it in that way?
But I will keep that in mind. Hey if it works,, then I say do it.

 

[scottstaff]

i just did mine as the instructions said to do. i may try the wrapping and stuff like you suggest. it seems to work ok now.

 

[Topo]

I coil the cable tight around the pole and is rare when I get false signals, but what GoGoGopher says sounds interesting and I will try to see the difference

 

[doc-jim]

I guess the only thing to do is try the different routes. Trying snug clockwise wrap full length, Then CCW wrap, Halfway up straight - then wrap, & finally straight all the way up. Using Zip Strips would help to arrange the cable anyway you want. I want to see field trials..!!
I have a feeling the results will be minor at best, unless the cable was very loosely wrapped. Otherwise why make the cable long enough to wrap around at all? Let alone as much as it does. On the other hand, anything that can improve the outcome is progress... Who's willing to try it?
