White’s Electronics, Inc. -

Manufacturers of the World’s Finest Metal Detectors

Congratulations and thank you for choosing

White’s MXT Pro.

The MXT series, which by design marry “versatility & high performance” with “simplicity of use”, is a wildly

successful metal detector design. I’m proud to put my name on the MXT Pro. As well, I’m proud the MXT

is grouped among a handful of landmark metal detector designs. Among the highest tribute, success in

the eld has earned the MXT “benchmark status” for which all other metal detectors are judged.

Listening to successful MXT users, the MXT Pro adds the three things MXT users have been asking

for, Backlight, Multiple Tone ID, and Ground GRAB, a convenient way to update ground tracking from a

locked setting or temporarily lock ground tracking for multiple passes over questionable signals.

This instruction manual will give you a good understanding of the basics. There are no substitutes for eld

experience. Practice using your MXT Pro and then study this manual further. Before long, you may well

be teaching the experts a thing or two.

It is with pride we put our “American Made Label” on every metal detector we build. At our facility here in

Sweet Home, Oregon, USA, we’ve been proudly designing, building from scratch, and distributing world-

wide, the world’s nest metal detectors for nearly 60 years.

It has always been my philosophy to keep our people in Sweet Home, Oregon working by keeping our

customers happy. I’m proud of our metal detectors and the people here at White’s who build them for you.

Happy Hunting!

White’s Electronics, Inc.

“I am proud to say

all White’s Metal Detectors are

built in Sweet Home, Oregon USA”

Assembly Instructions

1. Remove all parts from shipping carton and check

the assembly page to make sure all parts are pres-

ent.

2. There are rubber washers between clevis/lower

rod and loop ears. Use only nonmetallic washers,

ber bolt, and thumb nut to secure loop/search coil to

clevis/lower rod.

3. Unlock “S” rod camlock and insert clevis/lower rod

into curved “S” rod so that stainless steel spring clip

buttons line up and lock into one of the adjustment

holes in the curved “S” rod. Turn camlock to secure.

The second or third adjustment holes are suitable for

average size adults. Individuals 6’ or taller should use

the fully extended position. Individuals well over 6’ tall

should purchase the optional Tall Man Rod.

4. Unravel loop cable and wind the cable around the

clevis and rod assembly, rst revolution over the top

of the rod. Wind cable all the way to the top of the

curved “S” rod, about ve revolutions. Use the black

cable retainers, one near the loop, and one near the

top of the curved “S” rod, to hold the loop cable in

place.

5. Unlock control box rod camlock and insert curved

“S” rod so that stainless steel spring clip buttons line

up and lock into the rod on top of the control box. The

“S” rod is designed to curve up toward the display.

However, those who prefer to sweep the loop close to

their feet may desire to assemble the “S” rod to curve

down toward the ground. Turn camlock to secure.

Plug loop connector into control box, screw lock ring

to secure.

6. Grip the instrument by the handle, with your arm in

the elbow cup with strap secure, and sweep the loop/

search coil over the oor. If the instrument t feels

uncomfortable, adjust the elbow cup by removing and

repositioning the bolt/thumb nut and installing

in one of the optional positions. If necessary, readjust

clevis/lower rod length with the spring clip buttons so

that the search coil can be held near the oor without

requiring stooping over.

7. Remove the protective paper from the two black

elbow cup foam pads. Carefully align pads on the in-

side of the elbow cup, one on each side of the center

rod, and press rmly into place.

8. Adjust the elbow cup strap so that it is loose

enough for you to slide your arm in and out without

loosening each time you want to set the detector

down. The elbow cup strap provides extra leverage

and control. However, some prefer not to use it.

9. Install battery as described in the next section,

decal facing down, with plastic tab and steel contacts

facing toward inside of battery compartment.

10. It should be noted at this point that the detec-

tor might not work as expected indoors due to the

high degree of metals used in modern construction.

It is best to tune and practice out-of-doors to ensure

stable, predictable results. Additionally, freshly- buried

targets will not produce the normal depth and dis-

crimination results of targets that have been naturally

lost and settled in the ground. Due to the abnormality

caused by digging a hole in the ground matrix, and

the sophistication of the ground rejection circuitry, it

may take a number of years for freshly buried targets

to respond at true depths and discrimination accu-

racy. The best way to determine true detection depth

is in real search conditions.

Batteries

Standard Battery Holder

1. Slide open the battery holder lid (decal side of bat-

tery holder) by applying gentle upward pressure on

the tab of the door so that it unlocks. Slide the door

away from the battery box exposing the cell positions.

2. Remove any old cells from the holder. Note the (+)

and (-) positions of each cell and the (+) and (-) for

each position marked inside the cell tray. Install new

“AA” cells noting carefully the correct (+) and (-) posi-

tions. If the cells are installed incorrectly, the detector

may require service by an Authorized Service Center.

3. Slide the door closed so that it snaps securely.

4. Insert the battery holder into the detector so that

the decal is facing down, with the battery holder

door tab and metal contact points facing toward the

inside of the battery compartment. Close the battery

compartment door and secure the two latches on the

bottom of the case. Hook the front of each latch rst,

and then press down on the rear.

Using the

Standard Battery Holder

1. The standard battery holder holds eight “AA” cell

batteries equaling 12 volts total. Alkaline batteries are

recommended for use with this model. During normal

searching conditions you can expect about 40 hours

of hunting time from a quality set of eight alkaline bat-

teries.

2. Non-alkaline batteries can be used in this holder.

When non-alkaline batteries or rechargeable “AA”

cells are used, detecting time (before replacement/

recharge) may be reduced to about 30-35 hours.

3. The battery voltage appears automatically on the

display when the Gain is used to turn the MXT Pro

“ON”. Once the batteries become weak (8 volts) “Lo

Bat” will automatically appear on the display during

searching. At that point the batteries should be re-

placed. Alkaline batteries provide some reserve time

after “Lo Bat” appears, rechargeable batteries do not.

4. The battery compartment opens by gently pulling

down on the front of each of the two latches (on the

bottom of the control box) releasing the catch and

hinging open the door.

Headphone use prolongs all battery life. Battery life

will vary a great deal with temperature, number of

target signals, battery type, brand, and shelf life. Al-

kaline Batteries may be used (in a pinch) well into the

“Lo Bat” indication. Rechargeable batteries cannot.

When traveling far from home it is always a good idea

to carry 8 extra penlight alkaline batteries with you.

Backlight use will slightly reduce battery life, 10% at

the lowest brightness, 20% at medium, and 30% at

the highest setting.

Rechargeable Battery (Opt.)

A rechargeable battery system is not standard equip-

ment with your MXT Pro, however, two different high

quality systems are available.

White’s rechargeable battery #802-5211, and charger

#509-0022 are the recommended standard system

and offer quick charge and overnight charge options.

(QUICK CHARGE IS FOR USA ONLY. It is not avail-

able on 220-240 volt.)

White’s Premium system, #509-0037 NiMH Charger,

#802-5285 NiMH Stand, and #802-5281 NiMH re-

chargeable battery offers extended search times, the

latest Nickel Metal Hydride capabilities for the MXT

Pro.

Non-rechargeable batteries will start to drop in

voltage as soon as they are put into use and then

steadily diminish in voltage till they no longer provide

adequate power. The optional Nicad rechargeable

battery pack, however, will diminish slowly (plateau)

in somewhat of a at line and then, near the end of

their useful life, very quickly decline. Regardless of

the battery used, for long search periods, backup

cells are always suggested.

Rechargeable batteries deliver fairly constant voltage

until they require a recharge. If you use them well

beyond low, they may be damaged, will deteriorate

more quickly than if you only use them till their volt-

age starts to drop signicantly. Therefore, recharge-

able batteries should be taken out of service and

recharged as soon as you notice “Lo Bat” on the

display.

Rechargeable batteries (depending upon the type)

may not provide the same amount of continuous use

per recharge compared to “one use life” set of quality

alkaline batteries.
