MX5
Owner’s Manual
The MX5 comes standard with a 9” concentric coil. Several
optional coils are available through your White’s dealer. Any of
the Eclipse-series coils (made for M6/MXT/DFX/V3) will
work with the MX5.
Sweep Methods
Proper sweep technique is
important with any detector.
Round coils tend to have a
conical pattern of sensitivity
as illustrated here. As such,
coverage at maximum depth
is less than the size of the coil,
so it is always recommended
that successive sweeps are
overlapped by about 50%.
In addition overlapping each sweep, it is important to keep
the coil close to and parallel to the ground. Pendulum-swinging
the coil results in loss of depth, and if the ground balance isn’t
perfectly set the variation in loop height will create a ground
response. The following illustration shows improper and proper
coil sweep motion.
Finally, sweep speed affects target response and depth.
Some detectors are designed for an exceptionally slow sweep
speed, some need a fast sweep. The MX5 works best at a moder-
ate rate of about 3 feet per second. Somewhat slower or some-
what faster is fine, but whipping the coil at a fast rate is a good
way to miss deeper targets. The bottom line is: swing level,
moderate speed, and overlap.
