C-All Single Beam Transducer

Product Usage Instructions

To use the Simrad C-All echo sounder transducer:

1. Mount the transducer flush with the hull plating or the bottom
   of a blister using the provided installation flange and clamping
   ring.
2. Alternatively, flush mount the transducer at the bottom of a
   drop keel.
3. Penetrate the hull using a cable gland which consists of
   bushing, washer, rubber gasket and packing nipple to connect the
   transducer cable.
4. 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.

Long-awaited solution
It is a well-established fact that the echo sounder 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 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.
The C-All transducer is a long-awaited solution for many users. With four different operating frequencies in a single transducer body, you get a complete frequency range. The transducer is also specially adapted to our Wide Band Transceiver (WBT). This means that you ­ with only a few main parts – can assemble a professional single-beam echo sounder suitable for all types of fishing.

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 bushing, washer, rubber gasket and packing nipple.

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 handling 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.
