Help and advice needed on Quattro

[philiprst]

I'm a new Quattro owner and need some friendly help and advice from someone with experience with this machine. I have read Andy Sabisch's book cover to cover but my Quattro does several things that are difficult for me to understand. I am sure this is due to operator error and inexperience.

One problem I seem to be having is with vanishing targets. I'll get a good audio signal, ID'ed as a coin. I'll get it again as I sweep back over. Then it seems to vanish into thin air. Andy's book suggests the wiggle method for pinpointing but also says that the Quattro may null out a target if it is gone over more than 2 or three times. This is almost mentioned as an aside; can anyone tell me exactly what behavior I can expect?

The second problem I am having is with the pinpointing mode, probably because I don't understand exactly how it works. When in pinpoint mode, does the bar chart indicate when the target is anywhere in the hot strip? In other words, do I always need to do two 90 degree scans to localize the object under the exact center of the coil. I have to say that very often the bar chart seems to saturate over a very large area compared to what the audio signal in target mode is telling me. I thought that this was telling me that I had a large deep object like a can being read as a coin, but the contents of my empty holes tell me otherwise.

Thanks!

Phillip: If I understand you correctly, about the problem with the vanishing targets. Do you think you might be close to some iron. You didn't mention what mode you were using. It might be the ground your digging in has some type of minerals(coal, iron ore) in it and when you break it up, your signal disappears. I had that same problem last weekend while I was relic hunting with mine. You might want to try Rick's suggestion."when you think you have a good target to raise the coil and let the threshold reset, then go over just that target and see what the ID is. Some will null out,some will change tone to the target actual ID and some will read the same tone as it did the first time, so you know it is a good target.". That might also help stop chasing those ghost targets. As for pin-pointing, what works for me is, I listen to where the signal is the loudest after doing an "x" pattern, at the same time observing the bars highest point in the box, if I need to I will press the pin-point button raise the coil a few inches off the ground and listen for the loudest signal, while observing the bars highest point in the target box. I hope I helped you. Keep me posted. Tony from Tidewater
