Overview
The CHASING Distance Lock Sonar is a dedicated add-on for CHASING ROVs that enables fixed-distance inspection and automatic collision avoidance. After setting a target distance in the App, the ROV can measure and hold distance independently in four directions—front, left, right, and bottom—to stabilize close-up imaging and reduce operator workload. Key specs: measurement accuracy ±25 mm, resolution 1 mm, blind spot <20 cm, IP68 protection, 10.8–26.4 VDC input, and maximum diving depth 150 m.
