To adjust the sensitivity on the HUMMINBIRD Piranha 1 Waterproof Fishfinder, follow these steps:
1. Press the POWER-MENU button on the unit to activate the menu system.
2. Use the right and left arrow keys to navigate through the menus until the SENSITIVITY menu appears.
3. Press the POWER-MENU button again to select the SENSITIVITY menu.
4. Use the right and left arrow keys to adjust the sensitivity level. A higher number will show smaller sonar returns on the screen, while a lower number will remove clutter from the screen.
5. Once you have selected the desired sensitivity level, the menu will automatically be removed from the screen after several seconds.
Note: The factory default sensitivity setting is 5. Adjusting the sensitivity level will also affect how sonar returns are identified as Fish ID Symbols - more fish will be detected at a higher setting, and fewer at a lower setting.
