Humminbird Ultima manual

4.Enabling Fish Alarm; Factory setting: OFF

The Fish Alarm alerts you with a chirping sound whenever the Ultima detects fish (or another object not attached to the bottom). To activate it, select FISH ALARM and press the ON-OFF button. A fish symbol reminds you that the alarm is on.

5.Using Zoom; Factory setting; OFF

Zoom provides an up-close view. To activate it, select Zoom and press ON-OFF. The Zoom view initially begins at the surface; pressing the UP or DOWN arrow adjusts Zoom depth. The range of the display is shown when Zoom is on and a "ZM" appears by the bottom range number.

The Zoom range depends on the current depth range: 3 meters in the 5 and 9 and 19 meter depth ranges, 5 meters in the 37, 55 and 74 meter depth ranges, and 10 meters in the 11 I to 185 meter depth ranges.

Remember: If Zoom is the last function selected, you can use the arrow button to adjust the Zoom depth or ON-OFF to switch Zoom on and off without having to press SELECT first.
