SonarPhone SP100, Руководство пользователя

Страница: 30 / 38

Before you begin the process of installing the transducer, check
your hull to find a spot where you will have a smooth water flow
along the bottom of the boat. You want to avoid ribs, rivets, and
gouges or scratches in the hull. These create turbulence in the
water and can scatter SonarPhone readings at high speeds.
To get a true vertical depth reading, the transducer should be
mounted parallel to the water line. However, a 10° tilt to either
side is acceptable. If the hull is reasonably flat with a dead rise
of 10° or less, mount the transducer along the hull bottom. If dead
rise is greater than 10°, mount the transducer with level alignment.
Install the SP200 Transducer Externally
1.
Assemble the stainless steel brackets to the transducer using the hardware
furnished. Do not tighten until final adjustments are made.
2.
Place assembly on transom at selected location with the front of the transducer
extending 1/2” to 5/8” below the bottom of the boat and with the front part against
the transom. The least amount that the transducer extends below the bottom is
desired. If too low, spray and turbulence will occur resulting in lost bottom
readings.
