Use ping echosounder as horizontal sonar?

Hi.
Have anyone tried to use ping echosounder horisontal? Wil this work.
I have tried to follow anchore chain from floating dock to anchor with bad visibility. I need some sort of sensor for help me with this type of job.

Hi @Fjosen -
While you can use the Ping sonar pointed horizontally, you’re not likely to get a return off a chain - it is a 25 degree conical beam! This means that only large surfaces will provide a return that gives a valid range.
The Ping360 on the other hand should pick up the chain, depending on how big it is, and let you position the vehicle relative to it. The best possible sonar for the job would be the Sonoptix Echo, which would provide essentially an acoustic vide-stream of what is in front of the ROV!
