From my understanding the gold gun is a receiver that measure signal strength,the signal strength showing on the meter.Metal long time burried objects would absorb low frec. raidio transmission,so when you point the gun towards the treasure you would have a drop or null in signal strength,that is how it works,i hear it works great for large objects or natural gold and silver deposits but not very well on small targets like a coin.I beleive it works but needs to be modified for smaller targets.
