    Low Q 2D Shots, Stripers and Beam Width!

    Some shots from the new low Q 2D transducer. These are big stripers on the Chesapeake bay. I took advantage of the opportunity to change beam widths and compare the differences.

    Great pics. What is the kHz range for narrow chirp? I'm trying to get an idea of cone angle and bottom coverage in narrow.

    If you state which Helix 9 SI version, what boat hull, and are you asking about a AIRMAR CHIRP transducer?
