Is a forward looking sonar / fishfinder worth adding?

When I outfitted my Catalina 470 for cruising, I installed Interphase Forwarding Looking Sonar.

That was one of the best gadgets I had on the boat.

It worked great moving around shallow rivers and it was invaluable in unfamiliar anchorages.

If I was outfitting for cruising again, I would definitely put one on this list.

In 2012, Interphase was purchased by Garmin and shut down.

Garmin now uses similar forward looking sonar technology.

Here is a test on five different units
