Deployment & Best Practices

Configuration Options
‍Ideal for moored coastal deployments with one Spotter or a network.Integrate up to two more devices (e.g. pressure/current) per Smart Mooring (max 3 total).

Depth Placement
‍Place hydrophone ≥ 5 m below surface to avoid noise interference.

Remote Configuration & Controls
Direct control via Spotter Dashboard, binary/ASCII commands, and Sofar remote support.
