1. I have never understood why the
deep penetrating frequencies
such as 50kHz typically have
a wider cone and the shallow
water 200kHz a narrow cone.
2. The reason I say this is because
in deep water the coverage area
is already quite large due to the
distance from the transducer,
so a wide beam is not that
essential - in fact, you want it
to be quite small in order to get
detail and target separation at
great depths.
3. Whereas the 200kHz for
shallow water should be as wide
as possible due to the much
shorter distance from the
transducer.
4. This is emphasized further
when trolling, even when the
actual depth is >1000ft.

Tip: Take care when choosing the right transducer/s for your fishing style.
