Assembly
1. Remove all parts from the shipping carton and check assembly diagram
to ensure all parts are present.
2. Install black rubber washers on fiber lower rod; attach search coil to
lower fiber rod. Use only the nonmetallic washers, fiber bolt, and fiber
thumbnut provided to secure search coil loop to the lower fiber rod.
3. Insert lower fiber rod into center rod so that the spring buttons line up
with one of the length-adjustment holes in the center rod. Turn the camlock to eliminate any slack.
4. Insert the center extension rod into the hand-grip section. Turn the cam-
lock to eliminate any slack.
5. Wind the search coil cable around the rods, first revolution over the top
of the rod, all the way to the display pod. Plug the cable into the connector
on the back of the display. Tighten the retainer ring securely.
6. Thread the velcro armcup through the slots on the armcup. With your
arm in position, fold the strap over onto the velcro so that the strap is
loose enough to to pull your arm in and out of the armcup.
7. Grip the detector and sweep the search coil over the floor. If the fit feels

uncomfortable, adjust the position of the lower fiber rod. The ideal position
allows you to stand up straight and sweep the search coil over the ground
without stooping over.
8. Install eight “AA” batteries in the battery holder carefully noting the + & -
positions marked inside the battery holder. Insert the battery pack, lining
up the contacts. Using a firm motion, snap the battery pack into place,
veryify that the Battery Retainer Buttons are engaged.
Tips on Batteries
• The MX 7 operates for more than 40 hours (without backlight and with
headphones) using eight quality “AA” batteries.
• High-quality “AA” alkaline batteries are recommended. Rechargeable
NiCad, Nickel Metal Hydride, or other similar “AA” substitutions work well.
Batteries near or above 2 volts per cell and higher are not recommended.
• Battery life will change with battery type, operating temperature, and
backlight use. Lowering the volume of the built in speaker or using headphones extends battery life.

Getting Started with MX 7
1. Press the power ON button. Upon initial power up, the detector defaults
to the Coin and Jewelry program.
2. Sweep the search coil from side to side, keeping it level and close to the
ground. Overlap each search pass by at least 50%.
3. Once a target is detected, indicated by a consistent beep, sweep several
passes over the target center and note the display identification and
target depth.
4. If the target indicates dig worthy, press and hold the Pinpoint button
(√/X). If tapped, the pinpoint button will lock in the Pinpoint mode. After
pinpointing remember to tap the pinpoint button once more to return to
Search mode.
5. The pinpoint spot is an imaginary line through the center of the search
coil. It is important to determine where this detection line begins and ends
on the coil. The pinpoint spot is in the center of the search coil
6. Sweep the target area slowly. The highest pitch and shallowest depth
indicate target center.
7. Practice with a visible object above ground, moving back and forth over
the target.
8. Use care in digging properly for the terrain. Fill in all holes and discard any
trash found in the proper receptacle. By not leaving trash and unsightly
holes behind you, open areas will continue to be available for you and
others to metal detect.
Controls
The MX 7 operates in either Search or Options mode. The detector will continue to provide audio feedback when in Options mode, but the display will be
used to show options rather than target information.
The Power button turns on the MX 7. Tapping the power button while the
detector is on will turn on the backlight. Holding the power button while on will
turn the detector off.
