Well the curse of the BB's hit me last night. For once I tried running a custom discrimination pattern to only receive all decimal and pre-decimal coins by using the learn function on the Explorer, but need to re-jig it a bit to open up the discrimination pattern a bit more to catch ID's that are off by a few digits (as we know coins don't always have perfect ID's when in the ground). Turns out it worked quite well, as most of the junk retrieved was falling only in the gold range (also sampled several gold rings of various sizes/compositions into the pattern).
First good target of the night was a wee bit confusing, numbers jumping around a lot but still strong and repeatable. Turned out to be a spill of 6x10c coins, with a 5c stuck to one of the 10c - nothing exciting, but nice to get a few coins in one hit. The 50c coin copped a mower hit, and still managed to find the other half a few feet away.
The 1948 threepence was a sunbaker - easy pickings, and the 1958 rams head shilling was also not far under the surface, just the way I like it.
The only downside to the hunt was coming across a fair few large holes that had been dug out in the turf, and simply refilled with the soil and no turf, leaving unsightly brown patches all over the place. Just to add to the issue, the junk from those holes was either left next to, or put back into the hole again.
