If you are looking for targets or coins that are older, you will more likely find them deeper and
not on the surface-therefore, using your Blanker will focus your energies. You will no longer
be picking up the surface clad coins which can be time consuming in itself.
The following tip applies to any Big Bud, with a Blanker mode, that doesn't have a depth
meter such as the Special Edition: With the blanker on, you can double-check your target for
its depth capability by turning on the Blanker to determine if the target is deeper than four
inches or shallower. If your Blanker is set at four inches and you are no longer getting a tone
on the same target that you were detecting before turning the Blanker on, then the target is
shallower than four inches. This is also a good technique to use on the Select 220-D to
confirm the readout on the depth meter.
The Blanker works even more efficiently when using the 4-Inch coil. Because of the narrow
focus of the 4-Inch coil, there is even less interference from the surface trash increasing
receptiveness to treasure items. It is recommended though to operate the Blanker at 2
inches instead of the maximum 4 inches when operating with the 4-Inch coil system.
Because of the smaller diameter there is a loss of depth which would limit the depth
capability when operating in the Blanker mode.
The most obvious advantage of using your Blanker system is when you're well aware that
the object you're looking for is 2 inches or deeper.
Manual Notch Techniques
The NOTCH Mode, along with the Disc/Notch variable control, allows for adapting to
special hunting circumstances. For example, one type of pull-tab may be recurring in an
area that you're hunting in. If you wanted to eliminate this one particular type of pull-tab while
bringing in nickels and most gold rings the NOTCH Mode in combination with the
Disc/Notch control can do it. By turning the Disc/Notch control counterclockwise from "Pull
Tab" setting while operating in the NOTCH mode, you will still bring in nickels and most
gold rings while eliminating that particular pull-tab. Note: The Quick Draw's NOTCH mode is
really an AUTO NOTCH; the Disc/Notch control turns into an Auto Notch Width control
which does not work as a manual Notch.
Hunting Near Sidewalks
When a coin is dropped on a sidewalk, it usually ends up right on the outside edges where
it rolled off. Because sidewalks usually have the most pedestrian traffic, you can be
guaranteed that many coins were dropped. When detecting near sidewalks, it is usually a
good idea to determine if there is any steel re-bar in the concrete. To determine this, just
wave the coil over it in All Metals-If there is re-bar in the sidewalk, it is usually difficult to
detect near it without getting false signals in the DISC mode. If there isn't any metal in the
concrete, you will be able to effectively hunt the very edges of it without false signaling.
Even if you were not getting false signals from the iron re-bar, the target will usually still be
canceled out because of the nearness of the iron. Iron will cancel out any treasure that may
be located near it. The 4-Inch coil can overcome this to a large degree; it allows your
detector to isolate targets closer to the re-bar than a larger coil would.
