How far ahead will I be able to see?
In most cases, forward scanning in the Probe mode is
approximately 5 - 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 mode 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 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 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.
