2.7.22 Configuration - Sound Velocity
Since the speed of sound in sea water can vary
significantly from place to place, the EQ 55 offers an
adjustment to this value. Changing the EQ 55 Sound
Velocity Setting will change the depth indication.
Typical sound velocity in sea water is close to 1,462
meters per second and that is the value loaded into
the EQ 55 at the factory.
Sound Velocity in sea water increases with
increasing salinity, temperature and pressure
(depth). Temperature has, by far, the most effect.
