Had a lot of fun today picking through a multitude of targets at an old house site today, wasn't really expecting any coins as the site has been done on a regular basis.
First good targets that appeared were a gold gilded broach/buckle, and a small gold gilded cricket related clasp, which obviously depicts a cricket ball. Many buttons and musket balls later, I hit on yet another SA dog tag, dated from 1890-91 - only the 9th registered dog in the area.
First coin was a roo penny, followed by a couple of half pennies from the same hole - all 1900's era. Not far away from those coins, the first Victorian penny was unearthed from 1879, then another from 1877, and last penny of the day was the best condition of the lot, an 1898 Veilhead Vic penny.
As I was heading back to the car, I got the faintest whisper of a high tone, thinking possibly some real good at depth. Wrong, after I excavated a plug, the pinpointer found nothing. Ran the Deus back over the spoil pile, and was greeted with a screamer high tone from an 1860 Vic Shilling. The coin must have been quite shallow, though looks like it was sitting on edge to get that sort of lacklustre response, certainly caught me off guard.
The coins were all clear targets and not easily missed on 18kHz, though you do have to be thorough on your coverage to have any chance of locating one - the 11" coil was used along with the "HOT" fulltones program.
