If your Garmin AIS 800 is showing a red boat that isn't actually there and is shadowing your movements, it's possible that you may be experiencing a false AIS target. False targets can be caused by a variety of factors, including radio frequency interference (RFI), multipath propagation, and even reflections from nearby objects.
To troubleshoot this issue, you can try the following steps:
- Check your antenna: Make sure that your AIS antenna is installed properly and that it's not damaged or obstructed in any way. A damaged or obstructed antenna can cause signal problems that may result in false targets.
- Check your connections: Make sure that all of your AIS connections are secure and that there are no loose or damaged wires. A loose or damaged connection can cause signal problems that may result in false targets.
- Check for RFI: Radio frequency interference (RFI) can cause false targets on your AIS display. Try turning off any nearby electronic devices to see if the false target disappears.
- Check for multipath propagation: Multipath propagation occurs when AIS signals bounce off of nearby objects and create multiple signal paths. This can cause false targets on your AIS display. Try moving to a different location to see if the false target disappears.
- Update your AIS software: If none of the above steps resolve the issue, try updating your AIS software to the latest version. This may help resolve any software-related issues that could be causing false targets.
If you're still experiencing the issue after trying these steps, it may be worth contacting Garmin customer support for further assistance.
