Hi guys. Sorry for all the posts...but I guess this msg board is here for that reason. I've learned quite a bit the last few days with my 550 already...but have a long way to go. A couple things I have noticed in my tests etc. First of all...I was a little disappointed in that some people told me the 550 would pick up coins at 8"...with a penny flat on the surface of the ground and lifting the coil up...I could not pick it up any higher than about 5". Secondly, most coins seem to give me a nice sound and a steady target ID no matter which way I sweep the coil over it. Where as tinfoil etc doesn't. One problem I am having is pinpointing. With coins, a couple of times I have been able to nail it right on the money. However, sometimes I just can't seem to find my target, and it's very time consuming and frustrating. Almost seems like the target is moving and I'm chasing it! When I pinpoint using the "pinpoint" feature, and I receive the highest signal I can get, WHERE under the coil does this indicate? Front Center? Center? At the notch in the center of the coil? I'm confused on this. Thanks guys.
 
Wess, Most metals break down in the ground creating a halo which the detector also sees besides the target. I had the same way of thinking many many years ago and it kept me from getting into the hobby because I felt my detector wasn't good enough to find anything, boy I was wrong. The 550 will do the job so I wouldn't worry too much about airtests.
As for the foil would you really want every target to sound great? <img src="/metal/html/smile.gif" border=0 width=15 height=15 alt=":)"> Different sounds, readings, etc. is what gives you the target information.
For pinpointing try raising your coil a few inches. The tone is strongest when the center of your coil is over the target. Try turning 90 degrees and swinging over it from another direction when you are having the problems. Either an irregular piece of metal of catching the end of rusty iron is where it's gettin ya. Too high a sens. while being new can contribute to this also.

Detect as much as you can. <img src="/metal/html/lol.gif" border=0 width=15 height=15 alt=":lol"> Only time in the field will teach you, a message board only helps a little. <img src="/metal/html/smile.gif" border=0 width=15 height=15 alt=":)">
 
Thanks for all the information. I realize I need to get my butt out there and gain experience and learn from trial and error, but a little advice from experienced people never hurts! I like to have all the info I can handle. Where abouts in Canada are you?
 
Yes, every little bit helps. I'm on the little treasure island to your east...PEI. <img src="/metal/html/smile.gif" border=0 width=15 height=15 alt=":)">
 
If you have the 7x10 coil move the coil side to side until you have the strongest signal then drag the coil straight back until the instant the signal stops. The target will be under the center tip of the inside oval on your coil. It helps to keep the coil off the ground as you do this
Coins will detect deeper in the ground than in air testing.

Thanks for the advice Bill. I took your suggestion on the pinpointing and it seems to work well. This should help keep the size of my holes down.
 
With just slight practice it is dead on. I dug about 30 coins this afternoon using the 7x10 and when I stuck my probe in the ground at the spot I designated on the coil I hit 99% of them with the first probe. That's as "right on" as you can get.
What the boys in the back room at Garrett fail to tell you is that this is an oval coil with an oval transmitter and an oval receiver and they throw and receive a signal a little different than a perfectly round coil.

Yeah I don't remember If I Told him to bump the sensitivity down - I've stated it so much lately. But he should run it at about 6.5 until he has played with it some.
I gave that advice to another fellow some time back and he went back over a park he thought he had cleaned out and found a slew of old coins he missed running high sensitivity.
Sensitivity is like driving in real thick fog at night. You flip your brights on and they just bounce back in your face and you can't see squat.
Bill
 
I like that headlights in the fog analogy. We all tend to want to run the sensitivity as high as we can to get maximum depth, but sometimes you don't recognize the good stuff for all the chatter you get, or waste a lot of time chasing signals that just don't materialize. Good advice for a lot of sites. HB
