AUSE

Attempting an excessive range for conditions.

Range is

dependant on local conditions such as in-band noise from man-made
and marine sources. If possible reduce noise or work at a shorter
range.

Beacon reply insensitivity.

This may be due to a fouled

transducer, or beacon fault. Clean beacon transducer with fresh
water. Try using a known working beacon.

Transducer reply insensitivity.

Check that the transducer is not

damaged or fouled. Clean the transducer with fresh water.

Obstruction.

The beacon’s signal may be blocked by submerged

parts of the vessel, seabed objects – man-made and natural.
Bubbles of air and gas produced by the vessel’s propeller.

Thermoclines.

This is due to abrupt changes of velocity of sound in

water due to variances of water temperature and / or salinity. The
effect of this can be to ‘tunnel’ or bend the acoustic signal away from
either the target or the transducer. If possible try adjusting the height
of the transducer in the water.

AUSES

Magnetic anomaly.

Strong magnetic anomalies can be beyond the

calibration  range  of  the  internal  compass.    If  a  metal  pole  is  being
used  to  mount  the  transducer,  make  sure  it  is  not  made  of  iron  or
other  magnetic  material!    If  possible  remove  sources  of  local
magnetic  fields,  or  relocate  the  transducer,  or  set  the  transducer
deeper in the water.

Dirty Transducer.

There may be grease or another substance on

the transducer’s surface. This can result is bearing errors due to
refraction. Clean the transducer with fresh water.

Transducer damage.

The transducer may have been damaged by

dropping or collision. This could result in the receive elements being
displaced sufficiently to give incorrect bearings.

AUSES

Magnetic anomaly.

Strong magnetic anomalies can be beyond the

calibration range of the internal compass. If possible remove
sources of local magnetic fields, or relocate the transducer, or set the
transducer deeper in the water.

Strumming.

Severe strumming can result in the compass giving an

unstable bearing, pitch and roll. Tether transducer or pole with rope
forward and aft to reduce strumming.
