Bit of a skill brush up today, hitting a well detected and nail infested church/house site . Wasn't expecting too much, was running the high frequency coil still on 14kHz, though with iron discriminated out, reactivity set on 4, and with the sensitivity and audio repsonse wound back a bit to dull down the iron feedback. Was looking to dig anything breaking through discrimination that wasn't obvious wrap around iron tone, and was surprised on how many targets I could still pull from the flogged ground.
The spoon although reasonably large was sitting sideways in the hole, hence only had a very small cross section to pick upon - just a hint of non-ferrous. Same for the half penny, a slight mumur of something non-ferrous several inches down. The ground is so contaminated that the pinpointer sounds off constantly in the hole, making it quite a chore to locate the actual non-ferrous target. Ratcheting back the pinpointer usually tones down the smaller iron in the hole, revealing the actual target that was initially detected - once the nails are extracted.
Iron masking is so bad here that you often encounter other non-ferrous targets in the same hole whilst searching for the orginal target. Hence why you really need to rescan the hole after each target is removed, along with removing the iron culprits that cause the masking in the first place.
The sixpence was previously missed sitting under the edge of a rotting log (pays to roll them over for a look), the threepence was once again just a repeatable mid tone inbetween other iron targets, didn't actually expect that to pop out being a lot lower tone than expected for such a coin.
The decorative hinged locket came from a hole right next to the half penny, took me a while to pinpoint that amongst all the other crap in the hole.
Amazing how you can train your ears to listen out for such non-descript but repeatable tones from the ground, especially after park hunting for much stronger and obvious high conductors that in comparison nearly blow your ears off. Most wrap around iron was easily identifiable, even the good sounding but faint iron - a quick pinpoint will usually show something much larger at depth not worth digging. Might not be a 100 coins, though still fun to pick up some silver in what is a challenging environment.
