[CVS-118MkII] [CVS-833/833C]  [CVS-841] [CVS-852]

CVS-852
15" Dual Frequency
Color TFT LCD Sounder

Professional Sounders available with 1kW, 3kW or 5kW output power.

New Professional sounder for smart fishing, the
CVS-852 series offers the following new features!

• Professional Specifications
  Dual frequency operation with user selectable frequency plus power output makes this sounder the No.1 choice for the professional fisherman. Furthermore, a unique signal processing system, which aids in the finding of weak schools of fish in murky ocean conditions, is built in as standard. By combining these features, you can use this sounder for a wide variety of fishing styles from shallow to deep sea applications.
• High brightness, wide angle Liquid Crystal Display
  The sounder offers a steady, crisp flicker free image on a 15 inch high grade Liquid Crystal Display, available both in daytime and nighttime operations. The display has a much wider viewing angle, permitting picture monitoring from either side, up or down.
• Display Color
  Background color and sounder color can be changed according to the lighting condition as well as your specific needs.
• Operation "Easy" Design
  Rotary controls and keypads, these operating devices are logically arranged, easy to find and straightforward to use, making operation at sea a breeze.
• Navigation Display
  Boat position, event, etc. can be displayed in Lat/Lon or LOP by connecting a navigator unit. Water temperature can also be displayed with an optional water temperature sensor (ST-80, 90 or 100) being connected.
• Entire Image Control
  Unlike conventional sounders, the CVS-852 Series has the ability to vary the gain of the entire image including previous captured images. This feature allows the user to go back and analyze ground that has already been covered in greater detail including density of fish school, activity and even type of fish.
• Improved Image Clarity
  A newly adopted LOG receiver assures a high definition image of fish schools, thanks to its low noise, wide dynamic range amplifier. The new receiver system also provides an optimized STC (Sensitivity Time Control) characteristic, which was designed from practical operational view points, using the inputs from skippers. These features help find schools of fish in better clarity whatever the ocean depth---shallow, mid or deep..
• High Data Refreshing Rate, 3900 ppm
  The transmission rate has been more than doubled compared to KODEN's conventional sounders, resulting in a higher rate of echo returns (For CVS-852C only). By combining this feature with KODEN's unique signal processing method, the fish detection capability is greatly enhanced. Our extensive tests have proved that the CVS-852 Series far exceeds the sounders in the same class in terms of detection capability.
• Enhanced Interference Rejection
  We have adopted a new approach in changing the Pulse Repetition Frequency at a logically selected random rate, causing interference to be almost completely eliminated, whether it is from the sounders on board the ship or from other ship's.
• Universal Designed TX/RX Module
  Unlike conventional sounders, the CVS-852 Series does not require you to change the expensive TX/RX module when a need is arisen (i.e. to modify its frequency or output power level).
• Compact and Waterproof
  Where to install? The choice is yours. The sounder can be installed anywhere on the boat, on the table, tilted console space or even on the fly bridge, thanks to a strengthened waterproof design that exceeds IPX5 requirements.
• Flexible Installation
  The system is composed of a Display Unit and a compact Transmitter/ Receiver Unit, giving the user a greater number of places for installation.
