- Reduced man power costs. - High speed data collection. - High resolution data. - Easily survey hazardous or inaccessible areas.

- High initial start up costs. - No survey beyond water-air interface. - Wet sand can cause errors. - “Shadowing” around objects or pronounced features. - Precise post processing.

- Fast capture, high resolution, safe survey method. - Ideal for upland beach surveys. - Cannot capture below water level or wet sand. - Far more detail than traditional RTK GPS surveys.
