Raymarine A65 GPS Chartplotter?

[TooCoys]

My boat came with a Raymarine A65 chartplotter, the GPS puck, and apparently it also came with a sounding unit called a Raymarine DSM25. As I'm understanding from brief research, this unit allows it to provide HD sonar and water data.

I cannot seem to find any tutorial videos, or review videos on youtube, so I'm currently reading the manual to see what capabilities it has.

Does anyone still use this chartplotter, or have you in the past, and would you care to share your opinion's of it?

This is what it looks like, minus the transducer (not sure if that is installed on my boat or not.)

Thanks in advance.
