Lock-Distance Inspection. Automatic Collision Prevention. The CHASING Distance Lock Sonar.The CHASING Distance Lock Sonar is a purpose-built sonar payload for the CHASING M2, M2 S, M2 PRO, and M2 PRO MAX underwater ROVs. Using real-time sonar-based distance sensing, it maintains a precise, fixed standoff from underwater structures automatically — delivering consistent, repeatable inspection imaging regardless of current, visibility, or pilot input. Automatic collision prevention adds a critical safety layer for confined space operations where clearances are tight and ROV damage is a real operational risk.Special order item — contact Maverick to confirm availability and lead time before purchasing.Key Features Lock-Distance Inspection — Sonar-based distance holding maintains a precise, fixed standoff from underwater structures during inspection passes — eliminating variation caused by currents, pilot fatigue, or limited visibility. Every pass is consistent, documentable, and comparable across inspection cycles. Automatic Collision Prevention — Real-time sonar sensing detects obstacles and prevents unintended contact with structures, walls, and debris during close-proximity operations. Reduces ROV damage risk in pipe interiors, bridge piers, dam faces, and flooded structures. Direct-Fit ROV Integration — Purpose-engineered for CHASING M2, M2 S, M2 PRO, and M2 PRO MAX platforms. No adapters or modifications required. Confined Space Ready — Designed for tight-clearance environments including pipe interiors, bridge piers, dam faces, and flooded structures where manual avoidance is difficult and precision is non-negotiable. Mission-Critical Reliability — Trusted for infrastructure inspection, public safety dive operations, and industrial underwater survey missions where consistent standoff distance is a compliance and documentation requirement.
