Thanks for the great tutorial. I've really learned something useful.

Is there a way to figure cone angle for a given kHz?

[@sonarangler]

Thanks for the question...the answer is a bit tricky... Transducer manufacturers can configure the crystals in a transducer any way they choose, so it isn't a linear relationship between kHz rating and cone angle. In some cases, the manufacturers have chosen to claim that their cone angles are proprietary (and therefore essentially a trade secret) making comparisons even more difficult. However, my research indicates that for 2D sonar transducers, the typical cone angles are as follows: 200kHz: about 20 degrees, 83kHz: about 60 degrees, and 50kHz: about 35 degrees (note that decreasing kHz doesn't always relate to wider cone angles). For scanning sonar (down and side imaging), CHIRP sonar (multi-frequency), and phased array sonar (LiveScope), comparisons of kHz to cone/beam angles--and resulting range capabilities--are highly unreliable. I hope this helps... Cheers, Capt. John
