T44 Metal Detector Professional High Sensitivity Pinpointing Gold Detector Metales Adjustable Tracker Underground Waterproof

T44 metal detector meets the technical specifications and environmental test requirements of metal detectors in the international market. The specific technical requirements, test requirements and inspection rules are as follows:
1. Power supply:
3VDC with 2 1.5V batteries; Working hours: not less than 40 hours
2. Indicator:
2.1, Visual: LCD LCD screen
2.2 Sound; Speaker or headphone
3. Display and function selection:
3.1. When using the machine to measure an object, 9 different metals are displayed above the startup display screen, and an indicator will appear above the corresponding metal
3.2. The function words on the left side of standby mode are all in a semi displayed state. If you need to select a function, press the (MENU) menu key and select the desired function back and forth. The selected function words will change from a semi displayed ghost state to a real display. After selecting the desired function, press “+” or “-” to increase or decrease the parameters of the device
3.3,DEPTH is the depth indication when the object is detected.
3.4, the mode words on the right side of the standby state are semi-visible, if you need to select the mode press (MODE) mode key, back and forth to select the desired function.
3.5. When metal is detected, the value of the object will be displayed in the middle. The more expensive the metal, the higher the value.
4. Menu:
4.1 SENS: Sensitivity;
Press the MENU button to select SENS. and then press “+” and “-” to adjust the sensitivity, there are 20 levels in total.
4.2 VOLUME: Sound volume;
Press the menu key (MENU) to select SENS. Then press “+” or “-” to adjust the sensitivity, there are a total of 20 levels
4.3 NOTCH: Selective Shielding.
NOTCH is any one or more metals that users can choose to shield against precious metals according to their own needs or preferences when using the detector.
4.4 GROUND: ground balance;
Press the MENU key to select SENS. Then press “+””-“to manually adjust the balance value.
4.5 Small bulb: backlight function
Press the MENU key to select “light bulb pattern”. Then press “+””-“to manually control the backlight brightness. There are five levels.
5. Mode:
5.1 JEWELRY: (referred to as Jewelry Mode)
This mode is set up to search for jewelry
5.2 COIN: (abbreviated as coin mode)
This mode only tests US dollars: 5, 1, 10, 25, 50, 1$
5.3 ARTIFACT: (referred to as the cultural relic model)
This mode is configured to find artifacts, where small iron objects cannot be detected and large iron objects are detected
5.4 CUSTOM: (Abbreviation: Custom Mode)
This mode allows the customer to set a mode according to the metal they want and can program the tone.
Custom mode programming tone steps:
(1) The machine is adjusted to CUSTOM mode;
(2) Press and hold the MODE button for about 1 second;
(3) press the MENU key to adjust the metal that needs to change the tone;
④ Use the “+” and “-” keys to select the tone (0=VCO, 1=bass, 2=low, 3=medium, 4=high)
5.5 A/M: (referred to as all metal mode)
This mode is not allowed to shield any metal, which requires high environment.
6. PINPoint (abbreviated as PP precise positioning mode)
PINPOINT IS USED WHEN THE USER MEASURES THE METAL IN THE RANGE DURING USE, BUT CANNOT ACCURATELY CONFIRM THE POSITION OF THE OBJECT. (This function can only locate the position and depth of the object, and cannot distinguish the type of metal.)
GG function (automatically balanced)
This function automatically changes the internal grounding setting of the detector to be equal to the phase of the ground you are searching for, calling for automatic ground cancellation, which will “retrieve” the basic value and store it in the detector
Steps to restore factory settings: ① Turn off the machine; ② Press and hold the MENU key while pressing the power button (note: this reset will delete any previous settings in your mode)
9. Working frequency 7.7KHZ
10. Working current:
When not detecting metal, the working current should be less than 30mA. When detecting metal and the horn is sounding, the current should be less than 60mA When the LCD backlight is lit, the increased current should be less than 15mA
11. Detection sensitivity:
After turning on the computer, adjust the sensitivity (SENS) to 9, take a 25-cent coin, 22cm above the center of the probe, move back and forth at a constant speed, the LCD screen should have corresponding instructions, and the horn makes a high-pitched sound.
The working mode is placed in PP, take a 25 cent coin, approach the probe slowly downwards at a height of 22cm above the center of the probe, and the LCD screen should have corresponding instructions. At the same time, there is a significant change in the sound of the horn
12, temperature:
Working temperature range: 0 ℃ (4 hours)~+45 ℃ (4 hours)
Storage temperature range: -20°C (8 hours) ~ +60°C (8 hours)
