X-TERRA: 705, 705 Gold Pack, 705 Dual Pack, 505, 305, 70, 50 Metal Detectors
18.75 KHz
811493011509
What sets this 9" Concentric Waterproof Search Coil for the X-TERRA Series of Detectors apart is its high-frequency operation at 18.75 kHz, making it an ideal tool for detecting smaller, low conductive targets such as jewelry on ocean beaches. This lightweight, durable, and advanced search coil is designed with innovative technology to provide optimal performance in wet or humid environments.
Unlike its 7.5 kHz counterpart, this high-quality search coil offers enhanced sensitivity, specifically engineered for the detection of small and fine valuables. It's a reliable accessory for your X-TERRA detector, designed to operate at one of three different frequencies: 3 kHz, 7.5 kHz, or 18.75 kHz. The operating frequency is determined by the coil in use, significantly affecting the detector's performance.
Generally, lower frequencies allow the detector to penetrate deeper into the ground, but with reduced sensitivity to small, low conductive targets. Conversely, higher frequencies increase sensitivity to small targets, albeit at a reduced detection depth. Therefore, operating your detector with this 18.75 kHz search coil will enhance your chances of finding small nuggets and fine jewelry, while lower frequencies (3 kHz or 7.5 kHz) are more suitable when searching for coins and relics.
In essence, this waterproof search coil is a testament to the perfect blend of functionality and innovation, designed to enhance your metal detecting experience with the X-TERRA series of detectors.
