The PI50 is designed to quickly update data. After the sensors have been submerged,
the receiver requires only three consecutive pings from individual sensors to calculate
and display their respective information. However, if you experience problems with the
reception, you may try this filter.

We recommend that you only use Heavy filtering if there are large fluctuations in
the displayed data, or if the rate of change is small. Reduced filtering is preferable,
since this shortens the delay between updating the changes in sensor location, and
the corresponding displayed information.

sensor data. These problems may occur if neighbouring channels are used, or if the PI50
is disturbed by other hydroacoustic systems in use on own or other vessels.
When you operate in an areas with substantial reverberation due to the bottom
topography, or in shallow waters, you may experience "jumps" or spikes in the data
received from the sensors. Such errors can also be caused by other types of hydroacoustic
equipment operating on the PI50 frequency range. This filter has been implemented to
remedy for such interference problem as well.
