Note
If you increase the output power, make sure that you do not choose more power than your
transducer can handle. With a correct setup with the transducer registered in the echo
sounder software you are safeguarded against this. However, if you use a third party
transducer that is not known by the echo sounder software, you may inflict permanent
damage if you increase the output to beyond the transducer's capabilities.

How to adjust the pulse duration

The length of your transmitted pulse is very important to how you can detect fish. A
short pulse duration gives you a very fine vertical resolution. This allows you to detect
scattered fish, and you can find those that move near the bottom. A long pulse duration
throws a lot more energy into the water, and the digital filters used by the receiver are
narrower. These filters will reduce the ES70's sensitivity for noise, but the length of the
transmitted pulse will give you stronger echoes. With the filters, a longer pulse duration
will provide longer range, but reduced vertical resolution.
