infinium falsing

my infinium is falsing continually when I use is. it does it with both my coils. it's not interference, because it makes no noise when resting on the ground. I have read all the info I can find. I have the control mounted on the shaft and the cable secured very well. I get a lot of high low falsing. almost no way to tell a good signal. I wiggled the cable by the coil and got some falsing. this is supposed to be a very stable detector, but yesterday my GM 2 was quieter. I believe I am doing the ground balance correctly. any help would be appreciated.

How high is your threshold setting??
 
How long do I need to pump the coil for the ground balance to set. It seems like its a GB problem. With either coil, I have set it to fast and pumped for what seems to be a long time and it doesn't change. Same problem in slow. The soil I'm my area is really hot red clay so that may be the problem, but I don't think so. It didn't work at the river either. If i keep the coil really steady and sweep slow most of the falsing goes away. If I move it for rocks or over rough ground it falses.
 
I had a similar problem with both the 8 inch Mono and the 10X14DD. I sent them back to Garrett along with the rest of the detector
and turns out BOTH coils were cracked. I got a new 10X14 MONO and it works beautifullly smooth. There were no cracks visible
but the repair department marked where the cracks were. Totally invisible, but that was the problem/

I bought this detector used I wonder how much it would cost for the repair, if that was the problem?

Try this GB procedure and let me know the results>

The Inf can be a bit slow to GB in iron stone country if it has been used in quiet ground for a while or at the beach.
As Dave said , make sure you batteries are good: when they are down to one beep the beast can get a bit noisy in high mineralisation or on salt.
Yes the DD may be a better choice, I would be inclined to try the 5 x 10, it will not get the depth of the large DD but it will do a better job on small nuggs with sharper signals whereas the 10 x 14 can be a tad wishy washy on the littluns.

In any case try to GB like this:

Disc to Zero, Threshold to 4 or 5 then with coil on the ground switch on, wait for beeps and then go through to lock and check for EMI, if good go to Fast Track and wait for threshold to settle, then pumpt the coil several times, then with coil on the ground select lock wait for threshold to settle the lift coil off the ground,: If there is a tone, select Fast T and place coil on the ground and wait for the threshold to settle and then select lock: Repeat this procedure until there is the least tone change when the coil is raised of the ground with Lock selected.
If there is still some remaining long low tones try winding in a bit of Disc in small increments(while still in Lock) up to around 3 and no higher than 4. Check the GB after each increment.
If the detector is now stable in GB then away you go If it is still giving long low tones then you will have to go through this set up again or try the DD.
If the detector is giving long High tones then there is something other than iron causing the noisyness.

Generally the Infinium handles iron mineralisation very well but there will be some extreme hot rocks that can set it off with long lo and Hi tones. If you can wind the Disc to the Iron Check position and still hear the tones at the same level then it is the iron ground causing the noise, if the noise quietens down alot in Rev Disc then there might be a metal target in the ground. If by the time you have set in a disc of approx 3 the noisyness disappears then there is likely to be some alkali salts causing the GB difficulty.
REMEMBER TO RESET THE DISC BACK TO ZERO BEFORE YOU REDO THE GB.

I'm betting it's bad batteries - Just because you get 4 beeps when booting up does not mean you are getting sufficient voltage to the coil. Use good quality copper top batteries or other known high quality batteries. I've been thru this and sounds the same as I experienced. I bought some discounted Interstate work-a-holic batteries and went thru much grief even tho at boot up I was getting 4 tones. Having both coils with a crack is possible but a long shot. However, it could be an internal electrical problem. A process of elimination so try batteries first.
 
All the previous suggestions are valid and should be looked into. However, I had the same issue during a 3 day hunt last year and could not figure out the problem (tried 3 different coils). Finally the problem showed itself. At some earlier point/day , I had screwed on the coil cable and the prongs on the connector piece had missed the provided holes, and not knowing this, I tightened it well. The result was that I had actually made "new" holes in the plastic/rubber and on subsequent coil changes the prongs were being fed into the wrong,'false' holes. I changed coils several times before realizing the problem, but all was well after I made sure the connection was done properly.
 
Thanks guys. I bet its the batteries. I was getting the 4 beeps but they are the stock rechargeable and are pretty old. I will get back after I have done some trouble shooting.
 
Let us know how it turns out
 
I had that exact same problem, only with the headphone connection. Thought the unit was faulty as it was not acting correctly and the signals were very weak sounding. I had bought the unit used, and the original owner had incorrectly screwed the headphones on without the pins in their proper place, hence making a new hole into the rubber. When I connected the headphones, it seemed they went on just fine, but not knowing the pins were not aligned correctly, I had one pin into the rubber hole when I screwed the connection on.

Needless to say I trashed Garrett for the headphone connection design ( but praised the Infinuim in general since once I corrected the problem, it performed great on the beaches I hunt). It is a great unit once learned, but those darned connectors are a pain. Since I put my GG underwaters on the Infinium I never take them off in fear of not getting a good connection again.
 
Well I finally made it out again this weekend. I charged up my batteries really good and hit a beach in central ca. I didnt have any problems with the operation of the detector. Ran smooth most of the time. I would get an occasional false but it didnt repeat so I knew it wasnt a target. I ran the stock coil the first day and wore out my arm. The next day i went out at low tide and used my 8 mono. It is a lot better coil for use in the surf. I would get an occasional false when the waves went over the coil, but not bad. I didnt find anything good but I did learn that the finny makes a good beach detector. Way better than my Outlaw in the wet sand. And alot deeper in the dry sand.
 
I no longer pump up and down when booting up. Also, I rarely hunt in Fast track unless I am hunting over cobbles and obvious large ironstone and hot rocks. If the ground has a relatively even/pebbly to small stone surface I simply set the coil on the ground, switch to slow and wait 20 - 30 seconds for the machine to start purring quietly. I then switch to lock as this gives better depth. Why pump the coil?? Shallow, deep, shallow, deep started making no sense to me when the finny is a pulse machine putting it's own signal to it's maximum depth and doing it hundreds of times a minute. It is a motion detector but I believe I get better performance by letting the machine balance itself to maximum depth. Then, I find swing speed to be the first problem for false signals when hunting. Keep it low and slow for less false signals. I don't see a big difference between fast and slow except a bit less false signals on cobble type ground where heavy ironstone/minerals. In fast track I still get false signals but they are more subdued and easier to identify as long as your swing speed is on the slow side. Try it - you might like not listening to all that noisy pumping up and down and maybe, just maybe you'll find your Finny running more quiet. Go ahead, break the rules!
 
I picked up an Infinium a few months ago and a 10" mono coil as well which I've been using. The last Az location I used it in had moderately mineralized soil. The threshold tone run steady and then where the ground would abruptly drop away, such as a cattle track, pothole or any abrupt change in the distance from the coil to ground I'm getting falsing signals?
Am I right that this is caused by changing coil-to-ground distance?
Thanks,
Morgan
 
I have not heard of a 10 inch mono for the Infinium?? 8 inch yes.10 x 14 yes
If the threshold changes when the coil is raised or the ground drops away then the detector is not ground balanced properly
 
Sorry there, FG. 8" Mono. Don't want to start any new rumors about a new coil. Thanks for the reply and feedback. I'll double check the GB.[size=medium][/size]
 
Because of the auto ground track of the finny it is a known fact that no matter how you ground balance if you swing it over a void it will false. Go ahead, GB till you're blue in the face and it will still false when swung over a void.
 
Hey Folks , 10-4 on the Gb'ing dope - for sure. Other solutions were already discussed cept' AU's. I still believe a small Moped Battery like the ML's would accomplish Much for Finny if it could be Rigged up. it's Output ~ I believe Current gain (not Voltage) that would De-mystify the power issues always discussed in relation to Finny.

Ray - are U still up the Road apiece ? Me & Gal been wonderin'
