several types of alarm devices are used to promote pool safety and or/backyard safety. Pool Alarm Systems can be used to detect intrusion into the pool and/or immediate environs and sound a siren or signal a remote sensor. Gate Alarms Systems are used to signal the opening a yard gate.

Alarms are designed to alert you to certain sonar "events" by sounding tones. With alarms, you don't need to constantly monitor the display, so you spend more time fishing. Eagle features three main types of alarms, and all are selectable on/off by the user. The FISH ALARM alerts you when a fish symbol appears on the screen, with different tones for different sizes of fish targets. The ZONE ALARM lets you set an underwater depth zone (e.g. 21 ft. to 53 ft.) and sounds an alarm tone when targets are detected in that zone. DEPTH ALARMS are triggered only by signals returning from the bottom. Simply set the depths you want - whether Shallow Alarm, Deep Alarm, or both - and the alarm tone will alert you when the bottom goes shallower, or deeper, than your settings.

Audio feedback on alert states, such as Too Shallow, Too Deep, Arrival radius, Low Fuel, etc. Some devices feature external output capability, allowing you to send alert state signals to speakers or lights.
