Trail brilliance

Trail brilliance may be adjusted on the BRILL menu.

1)Press the MENU key.

2)Select the BRILL menu.

3)Press the ENTER/SELECT key.

4)Select TRAIL and press the ENTER/SELECT key.

5)Operate the VRM or EBL control to adjust trail brilliance.

7)Press the MENU key.

1.27 Electronic Plotting (E-plot)

10 operator-selected targets can be plotted elec- tronically to assess their motion trends. Five past positions are marked for each plotted target.

A vector appears as you enter a second plot for a target and is updated each time a new plot is en- tered for the target. The vector shows the target motion trend based on its latest two plots.

Alphanumeric readouts for last-plotted or selected target appear at the bottom of the display.

It should be noted that the vector and alphanu- meric target data are not updated in real time, but only when you enter a new plot.

E-plot requires ship's speed input (automatic or manual) and a compass signal.

When speed is input by a navigator, own ship moves in accordance with course; not heading.

Plotting a target

Before plotting a target, select PLOT or ALL on the MARK & DATA DSP menu.

1)Place the cursor on the target you want to plot, and press the PLOT SYMBOL key.

2)Watching the E-plot timer on the PLOT mode, wait at least 30 seconds. Place the cursor on the plot symbol and press the ENTER/SE- LECT key. The plot symbol of the target flashes.

3)While the plot symbol of the target is flash- ing, place the cursor on the target again and press the PLOT SYMBOL key. The plot sym- bol shifts to the new target position and the previous position is marked by a small dot.

Figure 1-23 Plotting

Note: If a certain target once plotted is not plot- ted again within 12 minutes, the plot symbol of the target flashes. If you want to continue plot- ting this target, reacquire it within one minute, otherwise, the target will be regarded as a "lost target" and its plot symbol and target data will be erased. The larger the plotting interval, the less accurate the plotted target data. Plotting of each target should normally be made every 3 or 6 min- utes as far as possible.

FR-8251, FR-8111 specifications

Furuno has long been a leader in marine electronics, and its FR-8251 and FR-8111 radar systems continue that tradition. Both are advanced systems designed specifically for professional mariners who demand high performance, reliability, and technological sophistication in their navigational tools.

The Furuno FR-8251 is a powerful radar system that boasts a range of features tailored for commercial vessels. With a 25 kW transmitter, the FR-8251 delivers exceptional performance, providing a clearer and more detailed image of the maritime environment. It is equipped with advanced signal processing technology, including the Doppler processing feature, which allows for the detection of moving targets. This is highly beneficial for collision avoidance, as it provides accurate information regarding the speed and direction of other vessels.

Another noteworthy feature of the FR-8251 is its large, high-resolution display that enhances visibility and ease of use, even in challenging weather conditions. The user interface is straightforward, allowing for quick adjustments and easy navigation through the various settings. It supports a variety of display formats and allows for customization, enabling operators to tailor the information presented according to their specific needs.

On the other hand, the Furuno FR-8111 is equally impressive and designed as a more compact solution without sacrificing performance. This model comes with a 12 kW output and is specifically crafted for smaller vessels, yet it still delivers high-quality radar coverage. Utilizing Furuno’s renowned Automatic Target Tracker (ATT) technology, the FR-8111 enables mariners to efficiently track multiple targets, significantly enhancing situational awareness.

Additionally, both the FR-8251 and FR-8111 come with integrated ARPA (Automatic Radar Plotting Aid), providing users with sophisticated tools for navigation and collision avoidance. The presence of multiple target tracking empowers operators to make informed decisions, optimizing safety at sea.

Furuno’s commitment to reliability and durability is evident in both models, which are designed to withstand the harsh marine environment. Their robust build quality ensures longevity, while their advanced technologies offer peace of mind.

Both the Furuno FR-8251 and FR-8111 are excellent choices for professional mariners seeking cutting-edge radar systems. With their impressive performance, user-friendly interfaces, and advanced technologies, these radar systems set the standard in marine navigation, providing essential support for safe and efficient voyages.
