Interphase Proble Operation Manual page 51

The transom transducers are mounted on a stainless steel
kick-up bracket in order to minimize the possibility of
damage if striking a floating object. The transom bracket
will 'kick-up' at speeds in excess of 20 knots. Therefore, if
you intend on using the forward scan at high speed, you
will need to consider a thru-hull transducer.
How far ahead will I be able to see?
In most cases, forward scanning with the Probe is
approximately six (6) times farther ahead than the depth
of water. For example, if you are in 15' of water, you can
see about 90' ahead of the transducer. The range is
limited to 1,200' forward and 800' in depth.
Typically, if you are attempting to see great distances
ahead, only targets but not the bottom will appear beyond
300 feet ahead, because a flat bottom with no targets
(rocks, wrecks, fish, etc.) will be stealth or invisible to
sonar pulses at great distances. A rocky bottom or
approaching hazard will normally show up clearly on the
display, even far ahead.
The Sea Scout will provide you with distance and
direction of the targets, but will not provide depth of the
targets, as they may be detected by a pulse that has
actually bounced off of the bottom.
Can I see a regular depth sounder view of the bottom
and scan forward or zoom into the bottom at the same
time?
All Interphase products (TwinScope, Probe, Sea Scout,
Echoscan 8, and Advantage) provide both full screen
views as well as split screens for bottom charting,
forward scanning or zoom view (depending on the unit's
functions), and even Loran/GPS ready track plotting
views.
The most popular display is a split screen with bottom
chart (viewing the bottom as it passes under the boat) and
forward scanning view at the same time. You can
actually see approaching targets and then watch as they
pass under the boat.
Can I see the display in bright sunlight?
The Interphase LCD screen is one of the brightest
displays in the industry. The backlight is a full width,
cold fluorescent tube (reduces the chance of
condensation). In bright sunlight, the LCD screen will
actually show up brighter than in a well lit room. This is
one of the reasons that LCD screens are becoming more
popular in the marine industry.
Also important is the orientation of the display screen.
Notice that the Interphase display screens are wider than
they are tall. This provides a greater viewing area from
side to side, giving you more room for important
information. Many 'other brands' use a vertically
oriented (or tall) display screen which does not allow you
to see as much bottom information at one time. The tall
screen picture disappears faster, and is difficult to read
quickly.
Can I get speed and temperature with my Interphase
Sonar or Fishfinder?
All Interphase products are available with speed and
temperature sensors. A separate transducer is required
for speed and temperature input and display. The speed/
temp transducer is available with either thru-hull or
transom mounting.
It is not necessary to use a thru-hull speed/temp
transducer if the scanning transducer is a thru-hull
mount. Speed and temperature transducers can be placed
on a transom, aft of an inboard engine.
