The transmit and receive cycle is very fast. A
sound wave can travel from the surface to a
depth of 240' and back again in less than
¹⁄₄
of
a second; so it is unlikely that your boat can
“outrun” this sonar signal.
As the digital depth gauge transducer receives
sonar signals, it converts them to a digital
depth that is displayed on your digital depth
gauge. The depth reading is continuously
updated as you travel across the water.
Easy-to-use controls on the digital depth gauge
allow you to set the SHALLOW ALARM or DEEP
ALARM for an audible alert when the boat is in
extreme shallow or deep water.
The liquid crystal display (LCD) offers sharp
viewing, even in bright direct sunlight, and is
continuously lit for nighttime operation.
NOTE: Actual depth capability depends on such
factors as bottom hardness, water conditions, and
transducer installation. Units will typically read to
deeper depths in fresh water than in salt water.
