ability to see the same thing using two

actually two depth sounders built into

one unit. Each sounder has it's own

advantages. The goal is to give you

the best of both worlds so that you can

sounder. You truly have two separate sounders with two

separate transducers with separate controls.

107 kHz Depth Sounder
The first of the two sounders uses a 107 kHz frequency with
a 38° cone angle. This low frequency gives you a lot of power
throughout the very wide cone. Low frequencies have an
edge over higher frequencies by being able to cover a lot of
area and reach into deep water much more efficiently. Lower
frequencies also tend to filter out targets of very small size.
400 kHz Depth Sounder
The other half of the Edge
a 10° cone angle. This high frequency gives a very tight cone
for amazing precision. Higher frequencies have an advan-
tage over lower frequencies for these reasons. Higher fre-
quencies will also see small targets the low frequencies miss.
