Now here's the dividing line, whenever you're focusing on detecting nickels and gold rings,
you would have to turn the variable control completely counterclockwise. This would
guarantee that all valuable targets including gold, nickels, silver & copper coins are
detectable. The main problem with detecting nickels and gold rings is that you will have to
dig the ominous "beaver tails" and other scrunched up pull-tabs that fall under the same
tone and target reading.
Pinpointing Techniques
There are many effective techniques for pinpointing your detected targets. By making an
effort of pinpointing accurately before digging, you will save yourself the time and frustration
involved in digging a crater.
1. Drawing an "X"
This is a simple but effective technique. After receiving a signal, swing the coil a couple of
more times horizontally making sure it is a repeatable signal. Now swing the coil vertically at
the same point you have determined the target to be attempting to draw an "X". When you
have your signal centered on the "X", attempt to dig within a 5-inch circumference.
2. The Pendulum
With this technique, you will raise your coil a few inches above the targeted area waving it
more like a pendulum listening carefully where the signal seems to be the strongest. Try
drawing an "X" at the same height over the target making sure you have centered where the
target is located. Now slowly lower your coil making sure you're still getting your strongest
signal at the center of the "X".
3. "All Metals" Pinpointing (As Applied to No-Motion ALL METALS)
By using your ALL METALS mode, you can determine the size of the target along with its
location. It's important that you do not tune your Ground Balance for its highest threshold
when using this mode for pinpointing. The reason you have the capability of determining a
target's size in ALL METALS is because no motion is required when you're over the target.
A continuous tone will be emitted as long as the detector is over the target. This makes it
easy to delineate the size of a target while pinpointing at the same time.
Notes for Units with Manual Ground Balancing:
When coin-shooting, it's important to adjust the Ground Balance so that it is over
compensating for the mineral condition you're hunting in. In other words, adjust your Ground
Balance another quarter-turn counterclockwise after adjusting for mineralization. You will lose
depth, but it will be far easier to pinpoint small targets like coins, especially in heavily
trashed areas. If your detector is Ground Balanced for its maximum threshold, as is
described in your operations manual, you will get too many signals in heavily trashed areas
to determine the location of the target.
When to Use the Blanker Mode on the Big Bud Series
When contending with a lot of surface trash, it is recommended to use your Blanker. This will
not guarantee that you will detect a good target directly underneath a trash object, or will it
guarantee that all surface trash will be eliminated, but the odds will be on your side.
