hi rde,
Welcome to AAC.
Please post more details of your query, what water depths are you measuring ?

" System components for determining depth, and control units for sonar mapping " WHAT ABOUT THEM??
Are you asking for an explanation of how they work together??
Or wanting to build such a system?
Probably we can help with either.

 

There is a great deal of published information about sonar, operations and limitations. The bad news is that there are quite a few limitations, And the WORSE NEWS is that the transducers for the more detailed applications are expensive, even for 30 year old surplus with no promise of it being functional.
