DualBeam PLUS Sonar<br />
Your 900 Series <strong>Fish</strong>ing System uses a<br />
200/83 kHz DualBeam PLUS sonar system<br />
with a wide (60°) area of coverage.<br />
DualBeam PLUS sonar has a narrowly<br />
focused 20° center beam, surrounded by a<br />
second beam of 60°, exp<strong>and</strong>ing your<br />
coverage to an area equal to your depth. In<br />
20 feet of water, the wider beam covers an<br />
area 20 feet wide. The 20° center beam is<br />
focused on the bottom, to show you<br />
structure, weeds <strong>and</strong> cover. The 60° wide<br />
beam is hunting for fish in the wide<br />
coverage area. DualBeam PLUS sonar<br />
returns can be blended together, viewed<br />
separately or compared side-by-side.<br />
DualBeam PLUS is ideal for a wide range<br />
of conditions - from shallow to very deep<br />
water in both fresh <strong>and</strong> salt water. Depth<br />
capability is affected by such factors as boat<br />
speed, wave action, bottom hardness, water<br />
conditions <strong>and</strong> transducer installation.<br />
QuadraBeam PLUS Sonar<br />
(optional-purchase QuadraBeam PLUS<br />
transducer only)<br />
Your 900 Series 997c Combo supports<br />
the optional-purchase QuadraBeam<br />
PLUS transducer. QuadraBeam<br />
PLUS sonar provides an extremely<br />
wide (90°) area of coverage.<br />
QuadraBeam PLUS starts with two<br />
fan-shaped 35° 455 kHz Side Structure<br />
locating sonar beams to spot fish, bait<br />
<strong>and</strong> structure to the left <strong>and</strong> right of the<br />
boat over an area of the bottom that’s<br />
always equal to twice your depth.<br />
For a detailed view below the boat, QuadraBeam PLUS uses DualBeam<br />
PLUS technology, with precision 20° <strong>and</strong> wide 60° beams. QuadraBeam<br />
PLUS finds more fish faster, <strong>and</strong> can even tell you where to put your bait<br />
by showing if fish are to the left, right or directly beneath your boat.<br />
