I've notice a HUGE DIFFERENCE with the VLF E-Trac when detecting old, large iron. With the ETrac turn up, big iron objects scream at extreme depth--it's incredible. And also, there is a detectable halo around long buried iron objects, you can be 4-feet off-target and still be getting a signal.
Question: How much different is gold and silver coins in detectability than iron. (All the silver coins I've found were only an inch deep.)
If three (3) samples of metal: (1) 19th century iron, (2) gold coins, (3) silver coins, each sample the size of your fist,
were buried at 1-foot increments (1, 2, 3) how would the detection differ at those depths? Iron = 1st, Silver = 2nd, Place Gold = 3rd?
How deep can you detect each of these fist sized objects, knowing iron is super easy.
