SUPPORT > SYSTEM SETUP > RIGGING THE SONAR

Before putting your StarFish into the water for the first time, you need to ensure it is correctly rigged...

1. First, remove the circular securing ring from the end of the shackle pin.
2. Put the shackle through the steel cable 'towing eye', at the end of the strain-relief on the towing-cable.
3. Position the shackle over the third from front towing hole (see middle figure above) on the StarFish, and as you do, ensure that the towing cable passes under the shackle.
4. Secure and lock the shackle in place with its pin, and the circular securing ring. The rigged StarFish should look similar to the right-most image above.

If the cable is not held centrally to the StarFish body by the shackle, then the drag of the off-centre cable could prevent the StarFish from towing level, with one transducer angled more towards the surface than the other. The result of this would be uneven image intensity on the sonar display.
