Shallow water chirping

You hear the claims that chirp technology lets you see deep, and here is some real proof. A Garmin GSD26 with an Airmar 599LH transducer painting the bottom at an impressive 11,706 feet. That's over two miles deep. I think this is the current record for finding bottom with a marine chirp fish finder, or at least this is by far the deepest screen shot I have seen to date, and I have seen a lot of them. Look at the depth range scale. The bottom of it is at 13,200 feet, and I would bet given time we will see even deeper screen shots if anyone can find water deep enough. I'm sure the unit was using every bit of its 3000 watts on low chirp to do this. But this time, we are going to the opposite extreme to look at how well this technology operates in very shallow water.
