warm fresh water and cold salt water is about +/-30m/Second which represents a
change of depth of +/-2%, this must be viewed in context with typical depths of the

Velocity setting is the largest source of measurement error when care is not
taken in setting it correctly.
Internal Battery Charging
The SonarMite is fitted with an internal sealed Nickel Metal Hydride battery which
provides 1.5Ahr @ 10vDC and a mains powered battery charger capable of bulk and
float charging to give the most efficient battery cycle. The user should avoid running
the SonarMite until the batteries are completely flat as there will be a high risk of both
data loss and permanent damage to the batteries. The charger will illuminate
CONSTANT RED when bulk charging and FLASHING YELLOW when charged,
the charger illustrated may change if a local mains variant is required.
