Forward Vertical Scan, Downward (Traditional
View of Historical Bottom Chart), and Forward Side to
Side Scan! The Twinscope combines the features of the
Probe and Sea Scout in one unit. You can now vertically
or horizontally scan forward of the boat, with one display
unit.
The Twinscope from Interphase Technologies works like
an underwater acoustic radar to show "live action"
views of shallowing bottom conditions, underwater structures,
large forward obstructions and fish or schools of bait
out ahead of your boat. The Twinscope is the first affordable
navigational sonar with the ability to look far forward
and to the sides of your vessel. You can't afford to
be without this valuable tool. Utilizing an exclusive
phased array scanning technology the Twinscope can reveal
navigation hazards or suspended fish in the water in
front of your boat while monitoring current depth! What
could be safer than to see ahead, underwater? New! Interphase
Twinscope It's like having three units in one. The following
pictures are actual screen captures, these are not simulations.
The first screen illustrates the Probe mode (vertical
scan) with the vessel in 30.6' of water, and a sea wall
about 130' ahead.
Also note the range marks along the
top of the display (denoting the distance to targets)
as well as the range marks along the left side of the
screen showing relative depth of targets. The number
'90' shows the bottom most range mark distance. Bottom
and forward ranges are related, but you can adjust the
unit to search outward about 6 times whatever the current
vessel's depth.
The center screen shows the Sea Scout
forward scanning mode. Notice its striking similarity
to aircraft Radar. Phased array Sonar borrows much of
the technology from phased array Radar now used on military
aircraft! Like Radar, the Interphase Sea Scout forward
scanning Sonar will display target's distance and direction
from the vessel, but like Radar, it can not tell you
the depth (or altitude) of the target. Simply change
the vessel direction to 'center' the target on the screen,
then switch to the Probe mode (vertical scan) and you
can actually 'measure' the size and depth of the target
you found!
The lower screen shows our standard
(like everyone else's) downward looking sounder. Why
would anyone settle for this 'down only' screen, when
you could be looking ahead!?
