470 (H) x 353 (V) mm,
Effective display diameter: 340 mm
Echo Color: Yellow, green or white in 32 levels
2. Range scales and ring intervals (nm)
Range: .125, .25, .5, .75, 1.5, 3, 6, 12, 24, 48, 96
Ring: .025, .05, .1, .25, .25, .5, 1, 2,
3. Minimum range
30* m on 0.75 nm range scale
*Using a 10 m 2 test target at 3.5 m high above sea and
antenna at 15 m high (IEC 60936-1). Different conditions give
a different result, maybe close to 20 m in actual installations.
4. Range discrimination
30 m on 0.75* nm range scale
5. Range ring accuracy
+0.2 %
6. Presentation modes
Head-Up, Course-Up, North-Up, North-Up TM
7. Heading information
Furuno GPS compass SC-60/120 is a recommendable
heading sensor as a backup of a gyrocompass. Confirm with
your Administrations.
