Long-awaited Solution
The echo sounder’s operating frequency is important for good results. This
is because the echo strength of different fish species varies with frequency.
Some fish species are easier to find with a high frequency than a low one, and
vice versa. This is also important if you are going to find smaller species,
such as shrimp or krill. At the same time, lower frequencies generally have a
longer range. A low frequency allows you to find both fish and the bottom when
working in deep water. For these reasons, many echo sounder systems are
equipped with more than one transducer. Some people prefer two transducers to
work with two different frequencies, others want more. This increases the
price of the echo sounder and entails increased installation costs.
Installation
- The transducer is normally mounted flush with the hull plating or the bottom of a blister. It is provided with an installation flange, and by means of a clamping ring it is secured to a mounting ring welded into the hull plating or the bottom of a blister.
- The transducer can also be flush mounted at the bottom of a drop keel.
- The transducer cable penetrates the hull using a cable gland which consists of a bushing, washer, rubber gasket and packing nipple.
Product Usage Instructions
To use the Simrad C-All echo sounder transducer:
- Mount the transducer flush with the hull plating or the bottom of a blister using the provided installation flange and clamping ring.
- Alternatively, flush mount the transducer at the bottom of a drop keel.
- Penetrate the hull using a cable gland which consists of a bushing, washer, rubber gasket, and packing nipple to connect the transducer cable.
- When operating the echo sounder, choose one of the four operational frequencies (38, 70, 120, or 200 kHz) depending on the type of fish species you want to find and the depth of the water you are working in.

Rules for transducer handling
To secure the long life and accurate results, the transducer must be handled
correctly.
- A transducer must always be handled as a delicate item. Wrongful actions may damage the transducer beyond repair. Observe these transducer hand-ling rules:
- Do not activate the transducer when it is out of the water.
- Do not handle the transducer roughly, avoid impacts.
- Do not expose the transducer to direct sunlight or excessive heat.
- Do not use high-pressure water, sandblasting, metal tools, or strong solvents to clean the transducer face.
- Do not damage the outer protective skin on the transducer face.
- Do not lift the transducer by the cable.
- Do not step on the transducer cable.
- Do not damage the transducer cable, avoid sharp objects.
