3. POINTS

3.1 What is a Point?

In navigation terminology, a point is any location you mark on the plotter display. A point can be a fishing spot, reference point and other important locations. You can use a point you have entered to set a destination and create a route.
This unit has 30,000 points into which you can enter position information. There are four methods that you can use to mark a point:
• At your current position
• At cursor position
• Enter position from the [Points List]
• Enter position manually on the screen
When you enter a point, the point is put on the screen with the point symbol selected as the default point symbol, with the youngest empty point number. The position of the point, symbol and navigation information (range, bearing, etc.) are saved to the [Points List]. You can show or hide the points, and the default setting shows all points.
Default point symbol (default configuration is a yellow circle)
You can edit a point on the screen or on the [Points List].

4. ROUTES

4.1 What is a Route?

Often a trip from one place to another involves several course changes, requiring a series of route points (waypoints) which you navigate to, one after another. The se­quence of waypoints leading to the ultimate destination is called a route. The equip­ment can store 1,000 routes, with a maximum of 50 points per route.
You create a route by pointing and clicking geographical positions on the screen. These positions are marked with yellow circles.
You can follow a route that you have created, with the GOTO feature. When you follow a route, the points on the route are yellow circles and a red line with arrows connects between the points. The arrows show the direction in which to follow the route.
Routes can be edited directly on the screen or through the menu and the editing fea­ture available depends on route status (active or inactive) and method.
• Select a route to follow.
• Select a route to follow and follow it in reverse order.
• Insert a point(s) in a route.
• Add point(s) to the end of a route.
• Rename a route.
• Delete a route.
• Find information about a route.
• Connect two routes.

4.2.3 How to create a route with the Easy Routing feature

The Easy Routing feature automatically constructs a route between two points, taking into consideration the preset values for safe depths, safe heights and boat’s width, to provide you with an estimate of a safe route to your destination. Easy Routing can be initiated on points, on quick points, on track points, on route legs, on a position fix, on MOB position, on DSC points, on a cartographic object, and chart.
You simply set a start position and a destination. This can be newly entered points or any of the points mentioned above that are currently on the screen. (The total distance can not be longer than 100 NM.) Easy Routing then analyzes the path between the two points and creates a route, inserting legs in the route when necessary to get you away from areas which exceed the safety values set on the menu. Easy Routing an­alyzes each leg for safety in three levels: safe leg, potentially dangerous leg, and un­safe leg, and color codes them accordingly, green for safe, yellow for potentially dan­gerous and red for unsafe.
Note: A chart card must be inserted to use Easy Routing. Not all chart cards carry Easy Routing. The message "No charts with Easy Routing data found." appears if a chart card does not have Easy Routing.
EASY ROUTING DISCLAIMER: The accuracy of Easy Routing is limited by the avail­ability of electronic charts loaded on your navigation system and the accuracy of orig­inal source material used in producing such charts. Always remember that you should navigate with the most detailed and up-to-date chart available from FURUNO, and new information from National Hydrographic Offices may render your charts obsolete at any time. Easy Routing is only an aid to navigation and must be used in conjunction with conventional navigation practices. As the navigator of your boat, you are respon­sible for reviewing the suggested route against the official nautical publications and sit­uational awareness. You must edit and/or approve the suggested route before using it for navigation purposes.

5. NAVIGATION

This chapter shows you how to get to a desired destination by using “quick points,” saved points, and routes.
Before you go to a point or follow a route, make sure the path to the points is clear. Zoom your chart to check for hazards which appear on a smaller scale.

5.1 How to Navigate to a Quick Point

The advantage of navigating to a quick point, the cursor position, is that you do not need to save the point to the memory. However, the point is erased when a new quick point is entered.
Put the cursor on the position to mark as a quick point then long-push the POINTS/ GO TO key. Then,
• A yellow circle appears at the location, with the youngest empty quick point number below it. The navigation line (red) connects between own ship and the quick point, your destination. The line shows the shortest path to the destination and the direc­tion to go.
• The arrival area, the radius of which is set with the ar­rival alarm, is shown with a red dashed circle. When your boat comes within the circle or your boat moves through an imaginary perpendicular line that crosses through the center of the destination point, the audio alarm sounds and the arrival alarm icon appears at the top of the screen to alert you. The arrival area and XTE alarm lines are shown when the related alarms are active.
• The XTE alarm lines (red dashed lines), show the XTE alarm range, set with the XTE alarm. When your boat crosses an XTE line, audible and visual alarms are re-leased to alert you.

6.3.1 3D display description

The 3D display has native 3D chart design that allows full time 3D presentation. This true 3D environment gives you all of the information you require with no restrictions on the information you can see. You can plan your routes, enter points, etc. like on the 2D chart. To show the 3D display, select [2D/3D Mode] and [3D] from the RotoKey menu. The 3D icon, whose appearance changes according to display adjustment state, appears to the right of the orientation mode box.
The 3D display provides a 3D view of land and sea around your boat. Land is shown in different shades of green according to height above the sea level. Water is shown in different shades of blue according to depth. The 3D display has most of the same information as the 2D display. With both presentations available you can see the con­ditions around your boat from different angles. The 3D display helps you navigate when you are in waters that you do not know. Also, most functions of the 2D display, for example, destination setting, are available in the 3D display.
For best results make sure you have accurate position and heading data.

7. FISH FINDER OPERATIONS

7.1 How the Fish Finder Works

The fish finder calculates the distance between its transducer and underwater objects like fish, lake bottom or seabed. The results are shown in different colors or shades of gray according to echo strength.
The ultrasonic waves transmitted through water move at a constant speed of approx­imately 4800 feet (1500 meters) per second. When a sound wave “hits” an underwater object like fish or sea bottom, part of the sound wave is reflected toward the source. To find the depth to an object, the fish finder calculates the time difference between the transmission of a sound wave and the time the reflected sound wave is received.
The picture displayed by the fish finder contains a series of vertical scan lines. Each line is a "picture" of the objects under your boat. The series of pictures are put side­by-side across the screen to show the contours of the bottom and echoes from fish. The amount of history of objects that have moved under your boat can be less than a minute to more than one minute depending on the picture advance speed.
7-1
7. FISH FINDER OPERATIONS

7.2 Fish Finder Display

The fish finder screen provides a “picture” of the echoes found by the fish finder. Ech­oes are scrolled across the screen from the right position to the left position. The num­ber of minutes an echo is displayed on the screen is controlled by the picture advance speed.
The echoes at the right position are the current echoes. These echoes can be from individual fish, a school of fish, or the bottom. Depth to the bottom is indicated always, provided the gain is set correctly.
Both low and high TX frequencies are provided. (Frequencies depend on the trans­ducer connected.) The low frequency has a wide detection area, which is useful for general detection and understanding bottom conditions. The high frequency has a narrow beam width that helps you inspect fish.
The range, gain, clutter and TVG can be adjusted automatically according to your pur­pose (cruising or fishing) to let you do other tasks.
The color bar at the left edge of the display shows the range of colors used to display different echo strengths. Weaker echoes appear in colors near the bottom of the bar, and stronger echoes appear in colors near the top.

7.5 Automatic Fish Finder

Your fish finder can be adjusted automatically, allowing you to do other tasks.

7.5.1 How the automatic fish finder works

The automatic fish finder function automatically adjusts the gain, clutter, TVG and echo offset. The main features of the automatic mode are as shown below.
• Gain adjusts the sensitivity of the receiver to show the bottom echo in reddish­brown, the strongest echo (default color arrangement).
• Clutter automatically reduces low-level noise like plankton.
• The TVG function is automatically adjusted.
• The echo offset balances the gain on high and low frequencies.
• Range is adjusted automatically to always show the bottom echo.

7.5.2 How to select an automatic fish finder mode

There are two types of automatic fish finder modes: Cruising and Fishing. Cruising tracks the bottom, and Fishing searches for schools of fish. Cruising uses a higher clutter removal setting than Fishing. Do not use Cruising when your purpose is to find fish, because the clutter removal circuit can erase weak fish echoes.
To select an automatic mode, open the RotoKey menu then select [Auto Mode] fol­lowed by [Fishing] or [Cruising].

7.5.3 How to adjust the gain in the auto mode

The gain controls how echoes of different strengths are displayed. Gain is automati­cally adjusted; however, you can fine tune the gain according to meet local character­istics, etc. Set the gain to show a slight amount of noise on the screen. Increase the gain for greater depths and lower the gain for shallow waters.
To adjust the gain, open the RotoKey menu then select [Gain 50k] or [Gain 200k] fol­lowed by the soft control labeled with the frequency you want to adjust. The corre­sponding adjustment windows appears. Rotate the key clockwise to increase the gain, counterclockwise to decrease it.

7.11 How to Balance Echo Strength

A school of fish at a depth deeper than a school of equal strength in shallow waterap­pears in weaker colors. This condition is caused by the attenuation of the ultrasonic wave. To display the schools of fish in the same colors, use the TVG. The TVG auto­matically adjusts the gain with depth so that echoes of the same strength and different depths are shown in the same colors.

7.15.1 Considerations for ACCU-FISH
• The fish length calculated by this fish finder is intended for reference purposes; it is not a completely accurate measurement of fish length.
• The 600 W transducers which support ACCU-FISH 525-5PWD, 525STID-MSD and 525STID-PWD.
• To display fish marks and fish size using a 1 kW transducer, the integrated trans­ducer 50/200-1T or 50/200-12M is recommended.
• Echo intensity depends on fish species. When the fish length differs between the indicated length and the actual length, you can compensate the difference on the [FISH FINDER] menu.

If the width of the transmission line is 4.5 ft (default val­ue) or more, set the transmission line width with [ZERO LINE RANGE].
[ZERO LINE RANGE]: This feature adjusts the transmission line so that the line dis­appears when the menu item [ZERO LINE REJECTION] is turned on. For a long tail, increase the value. If the transmission line does not disappear, lower the TX power.
[FULL SCREEN GAIN CONTROL]: The gain setting can be applied to only new ech­oes or new and existing echoes. Turn this feature on to get the gain setting applied to both new and existing echoes. The advantage of the full screen gain control is that you can quickly and easily find the right gain setting for your conditions.

[FISH FINDER SETUP]: The [FISH FINDER SETUP] sub menu provides the following features.
Scroll
Item Function
[TRANSMISSION] Turn transmission on or off.
[TRANSMISSION POWER] Set the transmission power, [High] or [Low]. Interfer-
ence may appear on the screen when an echo sounder having the same frequency as your own is being oper­ated in the vicinity of your boat. In this case, select low power and contact the other vessel to request them to re­duce their TX power.
[TRANSDUCER] Select the transducer used. If you use the optional triduc-
er 525STID-MSD or 525STID-PWD, you do not need to select the transducer.
[TRANSMIT RATE] Change pulse repetition rate. Normally, the highest rate
(20) is used. When in shallow waters second re-flection echoes may appear between the surface and actual bot­tom echo. In this case, lower the TX transmit. The [[Au­to]] setting automatically adjusts the frequency and pulse length with depth.
[50 kHz ECHO OFFSET], [200 kHz ECHO OFFSET]
The echo offset feature compensates for too weak or too strong echo level. If the on-screen echo level appears to be too weak or too strong and the level cannot be adjust­ed satisfactorily with the gain controls, apply an offset to correct the level.

In the default bottom level setting (0), the equipment judges consecutive strong echoes to be bottom echoes. If, in that setting, the depth indication is unstable, adjust the bottom level. If strong vertical lines extend upward from the bottom echo in the bottom lock display, lower the bottom level to weaken the vertical lines. If the level is too low, however, it may be difficult to distinguish bot­tom fish from the bottom echo.

[SENSOR SETUP]: The [SENSOR SETUP] sub menu provides the following fea­tures.

Item Function
[DRAFT] The default depth measurement method is the distance
between the transducer and the bottom. To get the depth from the sea surface to the bottom, enter the ship’s draft. Entry of the ship’s draft is required if the bottom discrim­ination display is used.
[SPEED CALIBRATION] If the speed sensor generated speed is not correct, you
can add an offset to correct the on-screen speed indi­cation. (NMEA format speed cannot be corrected.) For example, if the indication is +5% faster than the actual value, enter -5.
[TEMPERATURE CALIBRATION]
[ACOUSTIC SPEED CALIBRATION]
If the temperature sensor generated speed is not cor­rect, you can add an offset to correct the on-screen tem­perature indication. (NMEA format temperature cannot be corrected.) For example, if the temperature indication is 2° lower than the actual value, enter +2.
The velocity of the acoustical pulse through water can vary depending on water conditions, which can affect the depth indication. Normally, adjustment of this setting is not necessary. If you feel the depth indication is continu­ously wrong, contact a FURUNO agent or dealer for ad­vice.

Zero line
The zero line (transmission line) shows the position of the transducer. The line disappears from the screen when the range is shifted.
Bottom echoes
The strongest echoes are from the bottom, and are normally shown in reddish-brown or red. The colors and the width change with bottom material, depth, sea condition, installation, frequency, pulse length and sensitivity.

Bottom contour
The tail from a hard bottom is longer than the tail from a soft bottom, because the hard bottom reflects more of the ultrasonic pulse. An echo from shallow water gives a stron­ger reflection than the echo received from deep water. A longer bottom tail appears on slopes, because of the difference in travel time at both edges of the beam angle. For the rough bottom, echoes are reflected on many different planes, which displays echoes in many layers, giving a 3D effect.

Hard bottom
Rough bottom
Nature of a bottom
The nature of a bottom is known from the intensity and length of the bottom tail. To find the nature of a bottom, use a long pulse length and normal gain. For the hard and rough bottom, the bottom echo is reddish-brown with a long tail. For the mud or sand bottom, the bottom echo has less red and with a short tail. A bottom with a lot of small parti­cles can give a long tail on the low frequency pic­ture.

Size of a school of fish
Usually the size of fish echoes on the screen is proportional to the actual size of the school of fish. However, if two fish echoes appear at different depths with the same size, the school of fish at the shallower depth is displayed smaller because the ultra­sonic beam widens as it propagates and a school of fish in deep water is displayed larger.

Density of a school of fish
If two schools appear with the same color at different depths, the one in deeper water is denser because the ultrasonic wave attenuates as it propagates and the school of fish in deep water tends to be displayed in a weaker color.
