| Advantage | Limitation |
|---|---|
| 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 logging | Battery life limits continuous operation to 6–10 hours |
