Awesome screen shots though! great pics!

di/si works off the Doppler principal. What that means is that your boat....kayak....has to be moving for your return....display....to show correctly. Depending on the angle you are moving to a fish using si, and depending on the size of that fish you can quite often see the actual shape of a fish. But most of the time with di you will be see what a lot of folks have described as "grains of rice". Crappie...bluegill.....give a very distinct return.....the minute you see it you know what you are looking at. One of the reasons everyone recommends the biggest screen you can get is because of the way fish are displayed in di/si. It does not take long to learn how to use di/si and with all the tutorials on the web one can be up and running in no time. I know for me that going out now in the kayak with the si it turns into an adventure....LOL. We have all heard the phrase "Ninety percent of the fish are in ten percent of the water". When you use a si unit it really drives that statement home. I have completely covered VFW Lake with my unit and was surprised to see just how much of that lake was void of fish.....but that is only 22 acres. Laurel Hill is over 300 acres so it will take me a while in a kayak to explore it. If you get one...and learn how to use it...you will be in a much better position to put fish in the boat. To me the best way to describe it as you can eliminate unproductive water real quick.
