[QUOTE="oldtimerROB, post: 397090, member: 8947"] Whilst gold prospecting in the Golden Triangle I have encountered a lot of degraded tin foil at the head of gold bearing gullies where nuggets were found-usually next to surfaced areas where the diggers set up camp.Tin foil was in use from the end of the 19th. century till mostly 1910 when aluminium foil was produced,but it continued until around WW2. Some areas like around North Dunolly have a very heavy concentration of small hot rocks. Found only a few bent nails but the tin foil is of great concern as I have wasted a lot of time and energy digging it up. I have a 10 month old VLF machine which can easily be set up to identify hot rocks or mask iron nails,but I have yet to learn how to set the second tone break to mask tin.I need an exact setting so as not to mask out gold. I go by tones alone.Have a 2,3 and 4 tone discriminating modes on my detector so there should be some way to mask the tin.I have not seen tin mentioned in my manual or how to mask it with the various tones. If anyone has solved this problem I would be obliged to hear about it as the prospecting season is not far away. [/QUOTE]
