GPX4500F is a high performance metal detectors, made by a strength

of more than 10 years of professional detection equipment manufacturer.This detector’s sensitivity and stability enjoy the highest level among

domestic products. In addition, The most prominent characteristics is that

the type of metal can be identified, allowing you to easily find the available

metal objects .which is the functions that other similar products are not

available. You can go to more places to start treasure-hunting activities,

search for coins, jewelry, gold and silver products with PALCON.

MainMainMainMain Fea ture:Fea ture:Fea ture:Fea ture:

1. High-brightness LED panel can generally displays the detected metal

type according to the signal strength.2. the all-metal detection mode is suitable for searching metal objects on the

ground, and can be a simple recognition of metals

3. In addition to LED panel display, it can distinguish metal type by tones

4. 9.5-inch disk waterproof probe that can detect in the shallow water.

5. equipped with an external headphone jack ,connected to a single-

channel headphones (headset-owned), easy to use; built-in high-capacityrechargeable battery, a low-voltage t function, with charger, Worked

continuously for more than ten hours whenfull of power

Checking the seven components in packing carton: the host box, detectingdisk, three pieces of combined telescopic rods, chargers, headsets. Thenfollowing the steps below:1.1.1.1. Take out the probe and the connecting rod 1, wring out one knob of

connecting rod, remove the knob connector, and make connecting rod 1insert into the probe rod, and then twisted tight knob fixed poles and

buckle on the connecting rod 1, make connecting rod 1 insert intoconnecting rod 2; hold down the V-shaped clip buckle on the S-tube ,then insert the other end of connecting rod 2 into S-tube, pay attention toensure that the spring buckle card stuck in the pole mouth.

3. Vertically stretch or shorten the proper length of the pole: holding thedetector in relax, the distance between probe and ground is 1-2 inches .Can use the butterfly-shape knob to adjust parallel position between theprobe and the ground. The probe cable can be wrapped around the poleby Velcro, pay attention to maintaining a certain degree of tightness.

4. Make plug which is in the end of cable of Probe set insert into the airSocket on the host seat. Note: Please test the plug in place, hear thesound of carbazole,then screwe. Do not force avoiding damage.
