Getting Started in Metal Detecting

Suffla Metal Detectors offer advanced technology for various metal detecting purposes like coinshooting and relic hunting. To ensure a smooth start, read these instructions carefully. Understanding the terms below will help to avoid frustration if you are new to the hobby of metal detecting.


  • Discrimination (DISC): Discrimination helps differentiate between valuable finds and junk. When your coil sends a signal to an object in the ground, the detector analyzes the response. Higher conductivity metals, like silver coins, yield stronger, clearer signals, while low-conductivity objects produce weak, choppy ones. By setting the DISC value, you can tailor your detector to ignore specific targets.  If the DISC value is set to 00, the detector can detect all kinds of metal. If you don't want to find certain targets, you can adjust the numeric target range. For example, the numeric target range for 5¢ is 11-20. If you set the DISC number to 21, your detector will not have response to 5¢.


  • Notch: Notching enables selective elimination of certain objects within the metal spectrum. This means the detector won't respond to the notched target during the detection once it is selected and notched out.


  • Target Identification: This function builds on discrimination by categorizing the type of metal detected, identifying more specifically what's in the ground. Target IDs can specify a range, such as iron or silver or even a particular coin.


  • Frequency: Frequency refers to the radio signal sent by the detector to the coil. Low frequencies penetrate deeper but may miss small objects. High frequencies are better for finding tiny items like gold specks.


  • Interference: Interference results from external sources disrupting your detector's performance, such as power lines, electrical transformers, or other metal detectors.


  • Sensitivity (SENS): Sensitivity adjusts the detector's signal amplification. It helps counter electromagnetic interference (EMI), which can arise from nearby electronic devices. EMI comes from most household appliances, so YOUR DETECTOR CAN BEHAVE VERY ERRATICALLY INDOORS. If you want to test it indoors, turn off the TV and microwave. Lower sensitivity may reduce static in cluttered areas (e.g., a construction site loaded with nails and junk will cause a lot of static), while higher sensitivity can help locate deeply buried items.


Remember, learning these terms and their practical applications will enhance your metal detecting adventures and help you uncover hidden treasures while avoiding unwanted distractions.
