The FXL 19 deep black sonde operates at depths of up to 25.9 meters. Suitable for all DigiTrak F2 and F5 locators. Frequency 19.2 kHz. The probe transmits 12 clock positions and inclination with an accuracy of 0.1%. Switches to standby mode after 15 minutes. Operating time increased by 2 times - Power consumption reduced while maintaining signal strength. Power consumption of the “branded” sonde in operating mode is up to 150 mA, while ours upgraded model consumes 75-85 mA. In the drill head, power consumption increases by 70-100% due to losses: the original sondes consume up to 250 mA, while the upgraded ones consume 120-150 mA. Increased reliability when working in heavy soils or in percussion drilling rigs - The sonde's structural elements responsible for trouble-free operation in harsh conditions have been reinforced.
