First of all you are instantly going to notice a lack of depth compared to larger coils, I noticed that immediately, compared to my Sun ray 8 inch of about 2 inches less depth. Because of this, I almost took it off and put back on the 8 but I didn't. There was one area of this lot that was a bus stop out front that my 8 inch did not like whatsoever, tooooo much trash is what I thought, so I tried the 5 inch. That there was trash, but also about 8 dollars in close to the surface clad, which the 5 inch could read as coins not mixed targets. After I cleaned out all the clad I was hoping to find some older deeper stuff with a larger coil but other than a wheatie there was none. However back in the yard, I found a 1958d Ben Franklin Half, absolutely mint perfect on edge at 4 inches next to a handful of roofing nails that my 8 inch had previously read as trash and obviously other detectors missed for the same reason. The Ben Franklin reverse appears to be a double die $$$$$ oh yeah, I looked in cherry pickers book and it is not even listed so I think my 5 inch Sun Ray coil just paid for itself the very first time I used it. I also found in a corner where two fences meet, a perfect 1932 silver Washington quarter at about 5-6 inches down. I couldn't even fit my larger coils in this spot. After I cleared out the surface coins and close to one another targets, I went back over the area with my 8 inch and found an Indian head, a couple of wheats, another silver Washington quarter, and a State of Washington Tax Commission Tax Token. I also found a token "This token is my contribution of 25 cents to saving old iron sides and is deposited in the national bank of patriotism" It has a picture of the ship and it is utterly perfect, not an imperfection anywhere, no idea of its age or value. My point, go get a five inch coil, no you are not going to use it every day, but it has a serious purpose. I'm really glad I got mine, thanks Ray.
