Multibeam vs Voxometer
Survey
Polynesian Wreck Malta survey comparison
The Polynesian wreck lies at around 65m depth. Wrecks are the supermodels of the underwater world, but they do serve to illustrate a point.
Early in 2025, we did a baseline survey of this wreck using the Sonic 2026 multibeam at 450kHz, passing over the wreck in 6 passes to get as much detail as possible.
We then went over the wreck in just a single pass with the Voxometer, where the improved result and detail is plain to see thanks to the MA3 Multi Aspect™ principle where the wreck was observed from different aspect angles, at different frequencies and at different times.
Increased productivity with Voxometer
With the Voxometer, surveys can be performed at high(er) speed, in a single pass, without compromising the data quality. There are no avoidable data holidays or the need to go back and re-survey the area.
What is evident from this simple survey example, is firstly the improvement in data quality from the Voxometer and being able to achieve this in a single pass versus 6 passes translates into a real time saving of around 80%!
Now just imagine what this could mean for your survey project!
