The Mad Dogs have equipped the sailboat Mad Dog Voyager with dual Color Interphase Twinscope stations from Garmin; one inside at the Navigation Station and one outside in the cockpit.

The Color Twinscope Forward Looking Sonar by Interphase (Now owned by Garmin) operates like an underwater radar. The color display shows a graphical representation of what it “sees” underwater, using color to indicate the strength or solidness of the object reflecting the sonar signal.

A moving beam, electronically controlled inside of the underwater transducer, sends a 90 degree arc sweeping in front of our sailboat or from side to side. When in Vertical mode, the beam is projected and sweeps from straight ahead to directly beneath our boat, displaying an underwater sonar image of everything that it encounters. This is very useful for determining the shoaling edge of the shoreline, locating underwater projections, rocks, etc. We haven’t found any sunken treasures with it yet, but we are always hopeful…
The Interphase Color Twinscope forward looking Sonar System in use
In Horizontal mode, the transducer sends a 12 degree beam sweeping from side to side showing us what it encounters in a 90 degree sector directly ahead and to the sides of the boat. Horizontal mode is excellent for navigation skinny passes, narrows, etc.
