Backlight
The MX 7 has a backlit display option for use in low-light conditions. Backlight
use will reduce battery life (slightly, 10% to 20%) but may be necessary in
some conditions. During use, tap the Power button momentarily to select.
Alternately, press Option, use the up & down arrows to select LIGHT, then use
the + & - buttons to select the desired intensity of the backlight. Press Options
again to exit, or wait 10–15 seconds to automatically time out.
Frequency Offset
When two or more metal detectors of the same frequency are used near
each other, interference (cross talk) among them is likely to occur. By slightly
changing the frequency of the MX 7, such interference can be eliminated both
for the MX 7 and for the other detectors being operated nearby. Interference
from another metal detector is typically obvious chatter, similar
to having your sensitivity set too high for the area, only often with a more regu-
lar pattern of sound.
When it appears another metal detector is causing interference:
1. Press Options and use the up & down arrows to select Frequency.
2. Use + & - to select among the 10 available frequencies. Frequency shift-
ing on the MX 7 is slight—not enough to result in any measurable differ-
ences in sensitivity—just enough to avoid interference from another metal
detector nearby.
Salt Track
The MX 7 is a single frequency (VLF) metal detector. More expensive multi-fre-
quency and pulse-induction metal detectors do have some advantage in wet
conductive (salt) grounds. However, the MX 7 provides for excellent results in
these wet conductive salt conditions. The MX Beach program has an extend-
ed ground balance range to accommodate use in wet salt sand because salt
(when wet) is conductive like a metal target is conductive. Other situations
where a person may need the expanded salt ground balance range added to a
program other than Beach include Relic or Prospecting programs. Thus, the
salt option is available in the Options mode and can be added or subtracted
from any program.
Relic hunting is often conducted in farm fields. These farm fields, when wet
and heavily fertilized, produce conductive conditions similar to wet conductive
salt. Add the Salt Track feature to the Relic program when searching heavily
fertilized wet farm fields.
In desert regions alkali (salt) patches are often found in good nugget shooting
areas. By adding the Salt Track feature to the Prospecting program, these
alkali areas can be searched effectively for nuggets even when wet.
