Questions and answers
we are looking for gold coins, what is the best setting as there is a lot of scrap metal in the ground and its going off everywhere?
To find gold coins in areas with a lot of scrap metal using the Fisher Labs F75 metal detector, follow these settings:
1. Sensitivity: Set it high for maximum depth, but reduce if experiencing excessive noise.
2. Ground Balance: Perform ground balancing first to minimize interference from mineralized soil.
3. Discrimination Mode: Use discrimination to filter out common trash metals like iron and aluminum pull-tabs.
4. Operating Frequency: The F75 operates at 13 kHz, which is suitable for gold and coins.
5. Searchcoil Positioning: Use the 11-inch elliptical Bi-Axial searchcoil for better detection depth.
6. Pinpointing Mode: After detecting a target, use the trigger switch to pinpoint its exact location.
These settings help maximize detection of gold coins while reducing interference from scrap metal.
