Speaking of Iron. I'd like to hear your takes, That is Master Eagle and Michigan Badgers, on running in all metal. I do this but ignore the Iron signals, I also use a 9x12 coil on my ace 250, some people say use descrimination but I like my depth at 10 inches or less. But I also know I'm missing prospective targets because of masking and because I'm using a large coil I miss smaller stuff too.
All-metal mode hunting started for me in the 60's because that's all we had back then. I dug almost everything. Many times I'd detect a large square nail only to pull up a nice coin or relic in the dirt
Then when discrimination got going, like everyone else I forgot about all-metal mode and my finds greatly dropped off and I got fatter.
One day while hunting an old park with my Wilson Neuman GBII, I decided to set it on all-metal and check the filled-in area around the outdoor restroom. I immediately got a soft tight signal. I dug a nice Indian cent and couldn't believe it! I figured that was lucky! I ended up digging about 8 Indian pennies within an area of about 4x6 feet. They ranged from 5-9 inches deep (and note that we're talking 1983 here!). Later I discovered there had been a gazebo located there back in the early 1900's.
Here's the big issue and almost nobody ever mentions this on any of the forums. Deep targets do not sound like shallower targets of the same type.
Air tests, shallow coin garden tests, and "tones" can be very misleading.
Here's an example that was shared with me from one of Team Nautilus's top hunters. This is not an exact quote:
When hunting CW sites with the Nautilus IIB we set the machine in discrimination mode with the discrimination knob almost to the off position. Once into a known hot area, we use the 15 inch coil and hunt slowly listening for the slightest "tick" signal. The 3-ringers and buttons come from 10+ inch depths and are often barely a crackled broken whisper "tick" or "click" sound (this is how team Nautilus wins every year!).
For today's THers I personally don't see a big need for true all-metal mode hunting. Today's discrimination machines are almost as deep in discrimination mode as they are in all-metal mode. Most people hunt yards and parks and really don't have the liberty to do a lot of digging to learn how to use all-metal mode. Those days are gone and all-metal mode hunting for coins is obsolete.
Here's a tip:
Depart from the idea that old coins will give a nice solid easy to hear positive signal. Usually this is not true. Run in discrimination mode with a low discrimination setting. Maybe just tune out tiny iron nails. Then listen for those subdued small tight signals. Raise the coil while swinging and see if the signal is lost when the coil is raised 2 inches or so. If it is, slowly turn up the discrimination until the signal is lost. Forget about ignoring broken signals because often they are deep coins. If you can still get a signal of any sort when the discrimination is past the iron range--dig it! Yes, even if your "tones" or "METER" says IRON.
Deep copper/brass/lead can sound a lot like iron. In fact, so can deep silver and especially gold.
Sorry to run on so long.
Extra added note:
Some people lately have been posting that finds are never deeper than say 7 inches. This is not true. Years ago people crowded together in parks with horses and buggies, etc. When it suddenly started to rain many made a dash for shelter. Soft muddy clay and heavy horse hooves, wagon wheels running over coins...you get the idea (deep coins). This is double true of CW sites
