What is CHIRP?
CHIRP is the most sophisticated sonar technology
available for use by the fishing and boating public. The word itself is an
acronym for Compressed
High-Intensity Radiated Pulse.
Standard sonar sends 1 single frequency at a time.
Since the only feedback is from this 1 single frequency, there is little
information to work with, limiting the clarity and resolution available with
Instead of sending just 1 single frequency, CHIRP
sends a continuous sweep of frequencies ranging from low to high. CHIRP
sonar technology then interprets frequencies individually upon their return.
Since this continuous sweep of frequencies provides CHIRP with a much wider
range of information, CHIRP sonar is able to create a much clearer, higher
CHIRP Scanning Sonar
CHIRP technology also enhances the performance and clarity of Garmin DownVü and
SideVü scanning sonar to provide the clearest sonar images on the water.Types of Sonar
Traditional HD-ID™ Sonar
Traditional sonar that is available on Garmin fishfinders. HD-ID sonar
transmits two frequencies, generally either 77/200 kHz or 50/200 kHz. Our
echoMAP and GPSMAP chartplotter/sonar combos have Traditional HD-ID sonar
CHIRP sonar transmits a sweep of many frequencies within a long duration
pulse. The equivalent sound energy is hundreds of times greater, resulting
in more energy on target. This provides huge advantages in detail,
resolution and accuracy at much greater depths. CHIRP is built into our
GPSMAP chartplotter/sonar combos
sonar is unlike anything you’ve ever seen on the water. Use the Panoptix
Forward or Down transducer with a compatible Garmin GPSMAP unit to see all
around your boat in real-time. You can see fish in the water column in
3-D. You can also see your bait cast into the water and watch it as you
reel it in. You can see fish swimming in front of or below your boat. You
can even see them chase your lure. But
to truly appreciate Panoptix, you have to see it.
DownVü Scanning Sonar
This high-frequency sonar gives you a clearer picture of what's below your
boat, by producing a more detailed representation of objects, structure
and fish. DownVü with CHIRP technology takes it one step further,
producing an ultra-clear page with even more detail. DownVü scanning sonar
is built into our echoMAP combos, and DownVü scanning sonar with CHIRP
technology is built into our GPSMAP combos.
SideVü Scanning Sonar
SideVü shows you what is happening to the sides of your boat. An excellent
way of finding structures and fish. SideVü with CHIRP technology provides
an even more detailed and higher resolution image of what is beneath the
surface. SideVü scanning sonar is built into our echoMAP sv combos, and

signal through the hull.

attaches to the inside of a kayak, against the bottom and sends its
signal though the hull.
A stepped hull contains a notch (or step) that runs crosswise across the
boat hull and helps the boat generate more lift at higher speeds. If
transducer is mounted after the notch, the notch creates cavitation and
will interfere with sonar returns. For this reason, the transducer should
be mounted in front of the notch, closer to the front of the boat.
A cored hull refers to a hull with a void between the 2 layers of hull
material. Sonar cannot transmit through that void.
The deadrise angle is the angle between the horizontal line of the water
and your boat's hull
