Forward Looking Dual Axis Scanning Sonar

The Interphase Twinscope
Available in traditional gray case, shown with optional black case

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!?

Forward Vertical Scan, Downward (Traditional View of Historical Bottom Chart), and Forward Side to Side Scan!

The Twinscope utilizes 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. 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. The Twinscope's actual screen-captures from the unit. Contact Interphase now for more information. Like all Interphase Scanning Sonars, the Twinscope is designed, manufactured, and 12 hour tested in the USA.
