i have the Garmin 70DV, with 2D sonar and down imaging, no chirp transducer. The chirp SI transducer comes with their black box add on that gives side imaging. Not sure if I will be going that way or not. here's a few screen shots I took last week. The fish were biting in water 5-7 feet deep, so I didn't spend much time fooling around with the new unit. The old bridge shots were taken in some choppy water, so I think the clarity was effected. I think I am going to be very happy with it!![]()
