Im brand new to detecting and have the Nox 800. I thought id do a test bed and search around home first before going out...Im having a issue trying to figure out what is what...I have a VID numbers list but not sure i see galvanized nails, bolts washers etc... My readings are all over the place...so just started digging up yard 😂. Tons of stainless steel nails (For siding i assume) as well..when i go over these targets in park 2, 15hz and multi i get readings of 24-30and they also jump all over...so I go into all metal mode...Then changes to mostly less than 0 #s as well the higher numbers...Ive also have gone 90 deg to targets as well and get same reading. So getting a bit frustrating... I have threshold at 0, sensitivity at 20 or less, 2 breaks less than 0 for ferrous (volume at lowest setting) and then above 0 for non ferrous, recovery speed at 2 ....is there just too much trash and am i better just to go to a park to learn? there also seems to be a lot of black sands and small pebbles that are magnetized as well as a magnet picked up a lot..and my pinpointer was going off like crazy and i couldn't even find the target I know Im all over place here but a little guidance would be much appreciated! thanks!
