Did a quick one hour penny-popping hunt with the ACE 250 using the 9 x 12 coil, prior to picking up my kids at school today. The hunt was the area around (but not including) a playground. I got the usual pennies and one dime along with a magic key. (so
my daughter says)
When I got home, I changed the coil on the ACE 250 to the 4 1/2 inch sniper coil, which I got in the mail. First thing I did was to go and see how it acted in my 2 year old test garden. The machine could easily pick up the 6" penny and the 6" dime, with the sensitivity set ta either 7/8 segments or 8/8 (wide open). The 6" dime could not be picked up at all. If I decreased the sensitivity down to 6/8 segments, I lost the ability to pick up the penny, and could intermittently pick up the quarter. But, overall, that is pretty darn good for a small 4 1/2 inch coil.
Well, I wanted to try it in the real world, so I picked a real trashy bus stop, shared by two elementary schools. Now you could eyeball all the bits of tinfoil, chocolate bar wrappers, pull tabs, screw-caps and other miscellaneous items. I wanted to see if this coil could find some coins amongst all this trash. So after about an hour of hunting, I noticed a couple of interesting things that you should know. First of all, turn the sensitivity down to 3-4/8 segments, otherwise, the machine will be too sensitive and pick up too many signals including deeper targets. Secondly, go slow. Yes, in a large area with not too much junk, you can really make that coil fly and pick up targets, however, in an area with so much trash, you will miss many coins because the machine keeps resetting itself, and it doesn't get enough time to analyze a signal properly and give it a bell tone. Now, when getting a bell tone signal, you have to rely on the center of the coil to give you the most accurate pinpointing method. So, either raise the coil holding the pinpoint button in until you get just a faint small signal, and directly in the center of the coil is where the coin should be. Another way is to re-tune the coil. Do this by holding the coil over the target (centered) at about 3-4 inches with the pinpointing button held firmly. Now, stay steady and release the pinpoint button for 2 seconds and push and hold it again. Now when you pinpoint again, the coil doesn't have to move around very much to center it nor do you have to raise the coil to get the target centered. This second method may take some practice to make it work easily.
This coil worked just fantastic at this site. It was fooled by 3 flattened screw-caps and a piece of broken chrome reading as a coin, however, it did find 43 coins or $3.73. Pin pointing was really is easy, as the coil is so small. You just have to take your time and go slow in trashy areas. I'm sure I would have missed many good targets had I used a large coil through masking or just too many targets under the coil at once.
Oh....did I tell you that bus stops are very fertile areas for coins.
