Goldtarget
(AKA OldGT)
Went to a house site today with at least a 130 year history with permission of the owner. The two old sheds have recently been removed to make way for a modern backyard. The dust had settled a few days ago from the bobcat and I examined the ground. Most of the top was still undisturbed and after the top 3 inches remained intact with the exception of the driveway. Next week a shed and gardens will put in which is a bit sad really but thankfully I'll get a couple of days to give it a go. The going was impeded by the extreme mineralization, GB figures of 80+ and heavy emi so I worked up the sens to 50s just to get the ball rolling. The challenge didn't stop there, the ground was laden with a mountain of junk, the poor machine has a reputation for great recovery on multiple targets and did a pretty good job. I took a fluro can of pink marking paint gridded up and took another one in yellow to highlight targets. Cross referenced with earliest pics to determine likely tread paths but in short it was next to impossible to get through, each movement of the 11x5 DD had the machine singing, so for the first hour I went ahead on the solid non ferrous targets in the 60 square grid. 47 solid targets identified and dug up in the next 3 hours all in the top 3 inches. Lead, copper, brass, silver, aluminum, all manner of ids but alas junk, including brass handles, tap wear, small brass cup and shell casings, copper tubing, multiple copper washers, and shotgun primers, lead conglomerate, broken silver candle stick(scrap only) busted buckles, copper/brass press studs, tinfoil, screws, and unreadable trophy plaque. Upped the sensitivity to mid 70s id on 25 more targets but alas similar junk.
Went back and did 3 squares using the dig all targets running it on the edge using threshold drops method for more depth more steel than a sane man would handle, 15 non ferrous targets (mostly small coppers breaking down and casings bit of lead) and 57 to go. Not a single coin but I hold faith, it's justa question of coil time. I've learnt a few things today about the F75 and feel like we are beginning to bond, this site forced me to be focused instead of my usual lazy like foray in the parks. An old house site keeps you sharp. Deepest ferrous target lead piece at 9 inches, to be fair it was 7 by 5 cm surface area. Gave me a boost in confidence that if i had a decent nugget target reasonably shallow it may hit it. Pulled copper washers 2 cm across at solid 6 inch in harsh conditions. Be back tomorrow hopefully picking up something noteworthy to share.
