Impact Coil Connector Issue
Posted by: Cal_Cobra
Date: July 31, 2017 04:20PM
A friend and I just returned from a three day trip to the desert to detect several stage stop type sites we spent numerous hours researching to uncover their previously lost locations. We found a total of five sites.

The first site had sever overgrowth issues, we detected it for a few hours and decided that it had likely been previously detected as finds were minimal. I noticed that my machine, with the small coil attached, seemed to be running somewhat erratically - tones were "scratchy" sounding and I was only finding large iron (horse shoes, large pieces of cast iron, etc) and surface finds that were only a few inches deep, unless they were large. This was using the Di3 setting and DEEP settings, 14Khz or 20Khz made no difference.

The next day we detected a semi-virgin site, and while my friend was killing it (he made some amazing finds) I was again struggling with my Impact, and as above finding mainly large iron or close to the surface finds, unless large. Again the audio was erratic as were the TID's. I tried various search modes and settings, to no avail. Finally towards the end of the hunt I switched to the 11" DD coil and when I went to unscrew the coil connector, found that the connector practically fell out by itself. I mounted the 11" DD coil, screwed it together from both sides so it was snug, and I immediately noticed that the erratic audio and TID was gone and started making finds. Unfortunately by this time, it was too late as my buddy had already hoovered most all of the good finds (some incredible finds too boot)!

Yes I will accept the fact that this was user error. After the fact, I did somewhat wonder why the coil connectors weren't made in such a way that when screwed together, they would "lock" into position to prevent such an issue. I suspect that because of the tension of the connector, that if not firmly screwed together, it will have a propensity to jiggle loose and exhibit the behavior I experienced.

At any rate, just passing this along so nobody else has to suffer the agony of defeat that I experienced while watching by buddy make great find after great find.

hh,
Cal

Just curious, do you remember the last time you were in this area?
Put your small on on?

I have not experienced any problems in this area.

Man that's too bad Brian, I'm genuinely sorry to hear of this.----I know you two guys go to a lot of work in research, travel, etc. to hunt these places.------Do you think the coil connector could have been cross threaded---or did it just jiggle loose?-----I've had that happen to a F-75 once.------Either way, sorry to hear about this---a bummer!--------Del

Brian, glad to hear you got away to some potentially good sites, but sorry to hear you had a coil connection issue with the Impact. I experienced that, once, shortly after I got my 'Test Sample' Impact and found that I didn't have the connector snugged up. The two piece connector was different from what I had been used to and I just hadn't tighten it sufficiently. Haven't had a problem since then. Thinking back, it's possible I didn't have that first coil connections all that well fitted to begin with. Sort of pushed together but not really tightened.

Never a problems since then, and I seem to be grabbing an Impact first thing more often this past several months. Oh, I still make very good use of my other units, sometimes changing to a Relic or CoRe after I've hunted an area for an hour or two, but the Impact seems to be my first-grabbed devise, and no coil connection issues at all. Not since that first one that happened within the first week of Impact use.

Hi Del,

It was heartbreaking to find out that I had (self inflicted) equipment failure. One site that was particularly good was a mid 1800's stage stop, my buddy recovered TWO spurs, buttons, round balls, a beautiful GOLD ring (man if it could talk!), and numerous other finds right in the same area I walked over with my Impact...... frustrating to say the least as I'm sure if the Impact was functioning properly some of those finds would've been in my pouch......and to add insult to injury, it was a site that I determined we should try to locate and detect. The school of hard knocks education is tough :drinking:

Monte in retrospect, I suspect that what I did was only snug one side of the screw connector, but not the other. I guess it's a muscle memory habit, as all other detectors I've ever owned, you simply screwed the coils connector into the stationary receptacle built into the detectors control box and you're off to the races.

I'd probably killed it at that site with my Racer 2 :rolleyes:

Yep, that's pretty much what I did.

I just needed to tighten from both sides ... finger tight ... and all has been well. Overall a very nice package design. :thumbup:

Sorry to hear that Brian. I hope you made some good finds later.

Tom has way of out gunning his hunting partners....I think he can smell targets.

El I really don't know how he does it, he races around with his Exp2 and hoovers everything up...... ironically you always hear about how bad Explorers are in iron infested sites, how slow they are, how heavy they are, yet he cleans house with them :blowup:

Del funny story.....for starters he does have two Exp2's, but only carries one with him, along with a Tesoro Bandito. As we left one site Sunday we heard a hissing sound, a piece of sage brush punctured his sidewall and he wanted to hurry up and get his truck off the desert floor to a paved road in order to support the jack to change the tire. In his frantic rush to the road, he forgot that he left his Exp2 leaning up against a post - :rofl:

We got the spare tire mounted and went on our way to check one more site on our way home. Lucky for him, it was only 15 minutes away as when we got to the site, he realized that he'd left his Exp2 at the previous site - :yikes: Lucky for him that I suggested we check this last site (even though it was a bust), because otherwise, he'd left his Exp2 in the middle of the desert :lmfao: It's a very remote site, so the odds that anyone else would ever find it are low, but I don't think their thunderstorm proof and we're not planning to go back until the weather cools down :devil:

What I was asking, how long has it been since you had done a coil change, before you experienced your problem??
