Will pinpointing help to determine the size of a target with an Explorer?

Having trouble telling the difference between a quarter and a coke can. Whats the best way to determine size?
 
Try lifting the coil...if you get more than 6 or 7 inches its a target bigger than a quarter.
Also, the depth meter usually shows VERY shallow on big targets. Even a quarter on the surface shows about 2" on the meter.
If all else fails....Dig it and see...there should be a pretty obvious difference in the tone for such a large object.
Coins are smooth and specific...sorta "beep"..."beep"
a Can will be..."BEEEEP"
also you can find the limits of the target using the drag back pinpoint method...move 180 degrees and dragback pinpoint. A coin will ALWAYS pin point almost exactly in the same spot...a can will have a pinpoint differential 3 to 5 inches depending on the orientation.
 
It will tell exactly how large an object is. Also switch to digital, a can will show up at 30 to 31 where a quarter will be at 28 unless its right on the surface. After you practice a little you'll get to where you can tell the difference by the way it sounds cans have a slightly higher pitch and a ragged sound not a smooth deffinate hit like a coin especially if you move the coil very slowley across the target in discrim mode.
 
I'm with Steve, lift your coil. If you are a foot up and still getting a strong hit, time to move along. Or if it is a good site, dig the can and see if anything is nearby - you'd be suprised at what removing some junk can do. A large chunk of trash can mask a pretty large area - I have at least 2 older coins in my collection simply because I elected to dig some trash.
Pinpointing can also give you an idea about the size of the target. If you can move the coil quite a distance and still get a strong pinpointing sound, chances are that it is not a quarter. I got into an area with pieces of aluminum antenna scattered about and after 20-30 minutes, I was getting pretty good at avoiding that kind of trash.
