Interphase Twinscope Forward-Looking Dual-Axis Scanning Sonar
Interphase Twinscope Forward-Looking Dual-Axis Scanning Sonar
The Interphase Twinscope Forward-Looking Dual-Axis Scanning Sonar 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 Interphase Twinscope is the first affordable navigational sonar with the ability to look far forward and to the sides of your vessel. Utilising an exclusive phased-array scanning technology, the Twinscope can reveal navigation hazards or suspended fish in the water in front of your boat while simultaneously monitoring current depth.
The Interphase Twinscope is like having three units in one.
The top green screen shown here illustrates the Probe mode (vertical scan) with the vessel in 30.6 feet of water and a sea wall about 130 feet 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 centre green screen shows the Sea Scout forward-scanning mode. 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 cannot tell you the depth (or altitude) of the target. Simply change the vessel direction to centre 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 bottom green screen shows our standard downward-looking sounder - but why settle what for what everyone else also offers when you could be looking ahead?
The Twinscope utilises Tru-Scan technology recently developed by Interphase. Many boaters and commercial fishermen have asked us to combine the Probe and Sea Scout features in one unit - and this is it!
You can now vertically or horizontally scan forward of the boat with one display unit. The Twinscope automatically switches functions at the touch of a keypad ... it's that easy and it's completely solid state.
