CPA and TCPA alerts
The X100 allows you to manage the CPA and TCPA alarms, you might want to turn these off if you're navigating in busy waters.
In open ocean, you might want to set the CPA and TCPA to higher values. This allows the alarm to function more like a proximity detector, giving you early warnings about vessels entering a wide safety zone around your position.
Setting these alarms can help you stay aware of nearby vessels and avoid potential collisions by giving you a good warning before any chance of collision can happen.
Below shows you how to turn the CPA and TCPA alerts ON/OFF.
