DMC I has two modes: TR Variable Discriminate
and VLF Ground Balance. These two modes can be monitored
at the same time. The advantage of this is that
once the VLF ground balance has been adjusted for the
area you are hunting, you will find that the more conductive
the target, the weaker the sensitivity of that target
on the ground balance side. For example, an aluminum
pull-tab can be detected deeper than a quarter which
is approximately the same size. When using the
TR Discriminator, the very opposite happens...the quarter
can be detected deeper than the pull tap. The
Major advantage to listening to both modes at the same
time is that now only can you tell whether a target
is good or bad, but how good the target is.

A Word About Nautilus Search coils
Starting from the bottom up, Nautilus search coils
are wound and constructed entirely at the Tyndall Electronic
factory in Coats, North Carolina. New construction techniques
and materials have made them lighter and more sensitive than
ever before in the history of the company. Each search coil
is fine tuned to the electronics that it will be shipped with
insuring each detector that leaves the factory is optimized.
SIzes for the DMC coils are available in 6, 8, 10 and 15 inch
diameters. The six-inch diameter model is currently in production
for high trash coins and relic hunting locations. Early prototypes
tested of the 6 Inch coil were found to be excellent in areas
other detectorist walk away from.
All coils have thick mounting lugs
and a heavy duty cable strain relief. There are no
"whimpy" cable connectors used on the DMC I. All
connectors are strictly heavy-duty, nickel plated with a threaded
clamp ring. Nautilus search coils and the entire quality parts
inventory of Nautilus construction are engineered to keep
you in the field longer. Stainless steel hardware is used
throughout the DMC I construction.
