AdvantageLimitation
Rapid deployment (<1 hour from arrival to first data)Reduced survey swath width (typically 20–60 meters) vs. large vessel systems
Low operational cost (no charter vessel, small crew)Limited depth range; most portable systems are optimized for ≤200 m
High spatial resolution (cm-scale in shallow water)Susceptible to motion artifacts from small vessels in rough sea states
Real-time display and data loggingBattery life limits continuous operation to 6–10 hours
