These procedures are related to the basic use of the echo sounder.

How to change the ping rate

The is the parameter that controls how often the echo sounder shall transmit
Ping rate
acoustic energy (a "ping") into the water.
If you observe a pelagic echo on the sounder, and it seems to follow the bottom contour,
it may in fact be a false echo from the previous transmission ("ping"). The only way
to remove this false echo is to reduce the ping rate. If you do this, all the echoes from
the previous ping will have disappeared before you transmit the next. On old paper
based echo sounders the pen spent a long time on the rear side of the paper tray, and that
reduced the ping rate. The ES70 is a lot faster, and you may send out a ping even before
the energy from the previous ping has disappeared.
