I used to think that heave compensation was maybe having a Bloody Mary the next morning after a long night of swinging from the chandeliers with a lampshade on your head….
But yesterday, while testing out my new radar/sat compass installation, I found out what heave compensation is really all about.
After a long ordeal, I got the 24” Furuno and the SCX-20 sat compass firmly secured on the wheelhouse roof. The results (I got thick fog yesterday for the sea trial) were pretty stunnning

I decided to install the SCX-20 sat compass because at times, getting radar overlay on a chart is nice to have. An attribute I wasn’t expecting: What a handy tool heave compensation is when applied to sonar modules
I’ve had a DFF3D triple beam transducer that I’ve installed then taken off four boats over the years. It’s a huge transducer and can give good results though in my last three boats, the screen shots and targets were always a bit grainy (it hangs off the transom which it wasn’t designed for but that’s another story)
This was a screen-shot earlier this summer of the DFF3D triple-beam before adding the SCX-20. You can see how grainy the targets are

This was a screen shot of the triple beam I took yesterday using heave compensation from the SCX-20. It’s too bad there were no bait balls but you can see the clarity of the bottom returns. The wind was blowing, there were waves and side-ways rain, yet the SCX-20 kept the screen rock steady:

After that radar sat/compass installation that took a crazy amount of time to get things right, I celebrated with a Bloody Mary….. and then yesterday while out testing the Fish Gods rewarded me with a gift that I was absolutely not expecting :
