Pakkeinnhold
Please verify that all items listed below are present in your package.
- 1 x Irfora GT972 Metal Detector Unit
- 1 x brukermanual (engelsk)
- Note: 2 x 9V batteries are not included and must be purchased separately.
Nøkkelfunksjoner
- LCD-skjerm: Provides clear indications of metal types, signal strength, DISC and NOTCH settings, sensitivity levels, battery condition, and a digital display of the target ID.
- Three Audio Discrimination Tones: Emits distinct high, medium, and low tones to differentiate between various types of metal targets.
- NOTCH Function: Allows discrimination against unwanted metal types, enabling the user to focus on valuable items.
- DISC Function: Eliminates specific target categories by setting a DISC value. The detector will not respond to targets exceeding this numerical setting.
- PINPOINTER Function: Accurately locates the precise position of a detected target.
- Vanntett søkespole: Equipped with a 10-inch round search coil that is waterproof for effective searching in shallow water.
Oppsett og montering
Follow these steps to assemble your Irfora GT972 Metal Detector.
- Fest søkespolen: Secure the 10-inch search coil to the lower stem using the provided bolt and nut. Ensure it is firmly attached but allows for slight angle adjustment.
- Koble stilkene: Insert the lower stem into the middle stem, and then connect the middle stem to the upper stem. Adjust the length to a comfortable operating height.

Driftsmoduser og funksjoner
The GT972 offers multiple operating modes to optimize your search.
- DISC (Discrimination): Use this mode to eliminate unwanted targets. By setting a specific DISC value, the detector will ignore metals below that value. This is useful for filtering out junk metal.
- HAKK: The NOTCH function allows you to selectively accept or reject specific categories of metals. This is more precise than DISC for targeting or ignoring particular items.
- PINPOINTER: Once a target is detected, activate the PINPOINTER mode to narrow down its exact location. Move the coil slowly over the detected area until the signal is strongest and most stable.
- Audio Discrimination: The detector provides three distinct audio tones:
- Lav tone: Typically indicates ferrous metals or small, low-conductivity items.
- Middels tone: Often indicates medium-conductivity metals like some jewelry or older coins.
- Høy tone: Usually signifies high-conductivity metals such as silver or copper.

Searching Techniques
- Feiemønster: Hold the search coil parallel to the ground and sweep it slowly from side to side in overlapping arcs.
- Spolehøyde: Keep the search coil as close to the ground as possible without touching it.
- Water Searching: The 10-inch search coil is waterproof, allowing for detection in shallow water. Ensure the control unit remains dry.

Vedlikehold og stell
- Rengjøring: Tørk av detektoren med adamp klut etter hver bruk. Unngå slipende rengjøringsmidler eller løsemidler.
- Lagring: Store the detector in a dry, cool place when not in use. Remove batteries if storing for extended periods to prevent leakage.
- Søk spole: The search coil is waterproof, but the control unit is not. Avoid submerging the control unit in water.
- Batteribytte: Skift batteriene når indikatoren for lavt batterinivå vises på LCD-skjermen.
Feilsøking
| Problem | Mulig årsak | Løsning |
|---|---|---|
| Ingen strøm | Døde eller feil installerte batterier. | Replace batteries with new 9V batteries, ensuring correct polarity. |
| Erratic signals or false readings | High sensitivity setting, electromagnetic interference, or mineralized ground. | Reduce sensitivity. Move away from power lines or other electronic devices. Perform ground balance if available (refer to advanced settings in full manual). |
| Detector not finding targets | Incorrect discrimination settings, too low sensitivity, or target is too deep. | Adjust DISC/NOTCH settings to accept more metal types. Increase sensitivity. Sweep slower and closer to the ground. |
| Weak or no audio | Low battery, volume too low, or faulty headphones (if used). | Check battery level. Increase volume. Test with/without headphones. |
