How to handle my existing bottom survey data.

[Discreet]

Hi everyone,

I have a question about how to handle my existing bottom survey data.
I previously created a survey of my main fishing area using my old setup, which was a single-beam system without the Furuno SCX20 satellite compass. This year I upgraded my system and now I have both the SCX20 satellite compass and the DFF-3D multibeam module.

I’m wondering what would be the best approach:

• Should I start scanning from zero with the new system?
• Or should I scan over the existing single-beam data (without the satellite compass) that I already have?

If I scan over the old survey, will the new data replace the old one, or will it be averaged/combined with it?

What do you recommend in order to get the most realistic and accurate bathymetry possible?

Thanks in advance for your advice!
