What's under the boat?

The fishfinder application, when connected to a suitable Digital Sounder Module (DSM) and transducer, will help you to see fish, bottom structure and underwater obstructions. The image scrolls from right to left at an automatically selected range and frequency to provide a record of the echoes seen. You can mark with a waypoint any positions of interest that you may wish to return to. These waypoints are added to the waypoint list and can be used by other applications.

How do I interpret the bottom?

A thin line indicates a hard

 

A wide line indicates a soft

 

Peaks and troughs, indicate an

bottom (sand)

 

bottom (mud or seaweed cover)

 

uneven or rocky bottom or a wreck

 

 

 

 

 

Dark layers indicate strong signals; lighter layers weaker signals.

What influences target display?

The shape and size of echoes indicating targets, is influenced by a combination of:

 

Boat speed - flatter at slower speeds

Transducer frequency - broader at lower frequencies

 

Target depth - larger near the surface

Target size - larger targets return larger echoes

Marine RADAR specifications

Raymarine Marine RADAR systems are essential tools for navigating the high seas, providing boaters with unparalleled situational awareness and safety. Designed for both recreational and commercial vessels, Raymarine RADAR technology integrates advanced features and functionalities that enhance maritime experiences.

One of the standout characteristics of Raymarine RADAR is its high-definition imaging capabilities. Utilizing both pulse compression and digital signal processing, these systems can distinguish between various targets, such as buoys, other vessels, and land obstacles. The improved resolution helps users to identify potential hazards and navigate more safely.

Raymarine offers a variety of RADAR models, including the Quantum and HD Series. The Quantum RADAR employs a revolutionary solid-state design that delivers exceptional performance while consuming less power. This is particularly beneficial for smaller vessels or those seeking to minimize energy consumption. The Quantum antenna features Doppler technology, which enhances motion detection and allows for real-time tracking of moving targets, providing critical information on their speed and direction.

Another key feature of Raymarine RADAR systems is their integration with other onboard navigation systems. With access to Raymarine’s LightHouse user interface, the RADAR seamlessly connects with chartplotters, autopilots, and other sensors. This complete network enhances situational awareness, as users can overlay RADAR data on navigational charts for a comprehensive view of their surroundings.

Raymarine also prioritizes user-friendly operability. The systems come equipped with intuitive controls and customizable displays, allowing users to adjust settings quickly and effortlessly, ensuring optimal performance in varying environmental conditions. These RADAR systems can automatically calibrate to changing conditions, such as rain or fog, to maintain clear visibility.

Safety and reliability are paramount in marine navigation, and Raymarine RADAR systems provide robust weather-resistant features. Their rugged construction ensures they can withstand harsh marine environments, while advanced noise reduction technology ensures clarity even in choppy waters.

Finally, Raymarine's commitment to innovation ensures that their RADAR systems are always ahead of the curve. With regular software updates and advancements in technology, boaters can trust that their equipment will remain cutting-edge throughout its lifespan. In summary, Raymarine Marine RADAR systems exemplify the perfect blend of technology, performance, and user-friendliness, making them essential tools for anyone venturing out on the water.
