Hi,

I heard a whisper that one should run a GPX in tracking ( FROM SOME GURU ) , myself i have always run my 4000 in fixed.

Run it in tradking the last few swings & it runs real smooth & finding it.

Any opions?

DINGO

If you're running in Normal timing then there's no reason why you can't use tracking if the tracking speed has been selected as medium. Fast tracking speed runs the risk of removing a deeper target in a swing or two. If I use Normal timing then I generally run tracking as above.

Enhance or Smooth timings should be run in Fixed as the manual suggests. I know Ararat Gold runs tracking in these modes and is successful, but I'd suggest that on some of the nuggets I've dug when the signal was just a bare threshold change, I firmly believe that tracking mode would have removed them. The next signal like that I get I will do a comparison to see. Cheers.

Agree with all of the above. Couple of exceptions though. If running a small mono (8" and down) in Fine Gold timings in really shallow very hot ground where lots of little bits reside Tracking can help with some of the hotter sections. I used this method a while back in WA and it worked a treat especially in combination with the Boost audio filter, but beware if the ground gets much deeper than a few inches it is probably best to stick to Fixed GB and re balance often. In one case the ground so so mineralised (heavily metamorphosed Chlorite Schist) I had to revert to a larger 11" Commander mono coil as the 8" was saturating, I could have gone to Enhance but felt the trade off from the 8" coil in FG to Enhance was more than going to a larger coil allowing the inductance to deal with the mineralisation whilst taking advantage of the FG timings.

On another note, finding a target in Fixed and then checking the target in Tracking is not the best way to check if Tracking is costing performance. It will give you a bit of an idea of how much signal is lost due to Tracking mode but not a true indication as you already know the target is there. Best way is to go over a spot in Tracking first then re-run the ground in Fixed to see what has been missed. You would be surprised at the amount of "noise" you will ignore when you get in the habit of allowing Tracking to make decisions for you.

Clermont is fine except for the bloomin grass, DVD is progressing slowly but steadily. :-( Thanks for asking.

Hi Guys,
I always use my detector in Tracking so does that mean that I have missed some of the gold that would be deeper?

Isn't that the truth. On our Crystal patch lower end in the 3500 days (you've know the spot JP), I ignored a slight response on 2 occasions, dismissing it as ground noise as it was gone in 2 passes on both occasions. Using the 20" mono coil one day, I dug everything that murmured until I hit this target. First thoughts was "That's that damned ground noise again", but I decided to dig it anyway.

From a mere 16" came a solid 67grammer. It must have been lying on it's edge to give such a small response for a target that size at such a small depth. I had ignored it twice. Cheers.

i use to run tracking on the 4000 and i did find most off my gold with it set like this... then i was told i should be using fixed as i could be missing a lot off targets.... but since i'v been running it in fixed i have only found 2 bits... i'm running a 14" N/F coil. i'll put it back to tracking to see how i go back over some off the grounds i'v been...

If you are using the Sensitive Smooth timings of the GPX-4000 then it is recommended you keep your detector in Fixed GB. If using Normal or Sensitive Xtra or Salt then it is OK to use Tracking with the recommended Medium speed.

The reason you should use Fixed with the Smooth timings is due to the timing removing the bulk of the ground signal and also some of the target signal, using Tracking mode you run the risk of removing even more signal response thereby potentially missing gold nuggets especially at depth. It is for these same reasons it is not recommended to use a DD coil in DD mode in combination with Smooth or any of the "Smooth Class" of timings.

Hope this helps

thanks JP, i run most times i run these settings....speed slow, motion very slow, signal 16, extra sesitive, deep in audio, and on soil timings i run sensitive, maual tune 96 to 110... this is when i run the detector in tracking..... but with the other settings tracking speed slow, motion very slow, signal 16, smooth, quiet only when the grounds are bad then i run it in fixed i have the gain on 10 and no lower...
cheers
