Bottom Line depth finders, opinions?

[Raven]

until it finally quit werkin.... it was cool though having the sidefinding technology...you could cruise a lake and spot fish laterally instead of in the downward cone angle only and know which direction to throw your next cast...and many times i hooked up.
of course this was sweet water. The rational is that a tranducers cone angle is much like a flashlight beam shinning into a stand of trees ( ie cover, seaweed ,rocks ,structure) and the target may not offer a full presentation which can vary the signal response.
