After reading through, "Mastering the Quattro" I took mine out for a spin on Crandon Beach in Key Biscayne, Florida. I thought I knew it all after reading the book, needless to say I need to go back and read it again. It ended up being a good practice run, but I realize now that I am going to have to put in some serious time to really learn this machine's language. I thought I understood it, but now realize I have minimal understanding that will only improve with a lot of hands on practice. The positives: I think I got the cross saving thing down pat. I also am impressed with the ability of this machine to hit Nickels at the beach, I only found three, but they were deep! I also liked the stability of the detector, though at times I felt I was getting some falsing. The negatives: It is heavy!! I need to get used to swinging it compared to my Chest mount MXT. I am really feeling it right now. Also, it seemed to false on occasion, or maybe I was doing something else wrong. I did use Noise Control a lot as I moved from dry to wet sand to water. I wanted to take no chances. I also realized that at times I was swinging too fast and would catch myself and slow down. Here is where to problem arose. As I would sweep the coil, I would get a low beep and a visual display of "1" and "ring." I would attempt to get the same signal in the same area I just swept to try and confirm the signal and readings and I would no longer get any signal, audio or visual. This happened on other visual displays "1, 10, 11, 14, 26, 31" and different audio signals as well , both High and Low. I am probably not explaining this very well. Long story short, I got a ton of signals once and could not get them to repeat and therefore could not dig to see what was there as I could not be sure of where I got the signal on the sweep. It was a little frustrating. Anyone ever encounter this issue, if so what was I doing wrong? Additionally, there were at least a dozen times that I got an initial signal in the "20's" and after I took my first scoop out and checked the hole the signal dropped to the "10 to 17" range. I also had at least a half a dozen times where the signal disappeared completely after I dug my first scoop out of the hole. I could not get a signal from either what I took out of the hole or the hole itself. Again, if anyone had this issue, I would appreciate some feedback. Very frustrating. Lastly, I had about 15 different occasions where I would get a nice strong signal in wet sand and when I went to Pinpoint mode to try and pinpoint, there would be no signal for the pinpoint and the bars remained low. No matter where I moved around this point, I could not get the pinpoint bars to raise. When I would go back to search mode I would get the signal again. For some reason it would not pinpoint properly. I dug a few of these for the heck of it and found 1 pull tab and the rest after going down about 18" I stopped because I could not get a repeatable signal. I also notice in the water I would get a lot of 1 time audio signals that I could not get to repeat when sweeping the coil over them a second, third of fourth time. It was like whatever was there disappeared. Any thoughts on this would be greatly appreciated. All and all, I do not want to sound discouraged, because I am far from it. I knew getting into this that it was going to take some time. I like the Quattro and am getting comfortable with it. My totals for the day are as follows: 2 Nickels, 1 dime, 2 pennies, 51 pull-tabs. All coins were recent except for one Nickel which was 1964. The 64 Nickel was about 9 inches down in the wet sand. I did not dig one piece of foil or any iron. With my MXT I would have gotten a lot of foil along with the pull-tabs, but I dig everything that is borderline. Today, I was following the advice from the book. Any feedback from some experienced Quattro users would be appreciated. Best regards,
