Tip
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. The longer pulse duration will provide longer
range, but reduced vertical resolution.
These filters will reduce the EK15'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.
