What Lies Ahead
FarSounder’s 3D forward-looking sonar detects obstacles in real time.

Imagine operating your boat by only looking in a rear-view mirror, while someone tells you what’s in front of you. Sound a bit challenging? Well, as far as anything under the water is concerned, this is exactly how most boaters do it. The depth sounder tells you the depth of the water directly under the boat, but because of your forward speed, it is far behind you by the time you see that information at the helm.
This means every time you look at your depth gauge, you’re actually looking in a rear-view mirror at the bottom you’ve already passed over. The faster the boat is going, the farther behind you’re looking. So how do you know what’s under the water in front of you? The only way is by what your chartplotter is telling you, so you blindly push ahead trusting the information is correct.
