3 DEPTH FUNCTIONS
3.4.

Depth functions (optional)

To change between Log and Depth information press MODE. This function will
display depth in metres, feet or fathoms. To change unit see 4.2.6. A depth
sounder measures the time it takes for a sound pulse transmitted from the
transducer, to bounce on the bottom and be received by the transducer again.
The strength of the sound pulse decreases with the depth and is also affected
by temperature and pollution in the water. A soft bottom with a lot of vegetation
will also decrease the strength of the echo, which can result in poor reception
by the receiver. If no echo is registrated the depth reading will be three dashes
i.e. no echo.
