Pro Tip: Incorrect Heading Setting

- A customer was having issues with his console map always pointing the wrong direction when he was running. It turns out that his bow mounted Point-1 GPS antenna was getting inference from the trolling motor when it was in the stow position. I'll show you how to fix the problem.
These settings apply to HDS and Elite FS units.
Also, if you're curious what the background video is in the beginning, watch the video until the end and you'll see it. It's a pretty cool view of the state park boat ramp at Smith Mountain Lake in Virginia.
Remember: Do it right, do it once.

Great explanation of how a heading sensor should be used.
Thank you!
Excellent advice. I really like this type of video. Tips like these are helpful to everyone. Keep em coming my friend!
Thank you. That is a common problem that I have seen from multiple people. Hopefully, it will help someone and save them from frustration.
Thank you so much. ., this is a rare find.. I’m suffering the exact
I hope that this video helps you fix your problem. It is a common issue that I've seen and fortunately is straight forward to correct.
Thanks for watching the video.
Put the Point-1 at the transom. Set the console units to use Point-1 for both GPS & (magnetic) heading. Set the bow MFDs to use their internal GPS (not Point-1), but still use the Point-1 for magnetic heading. No unit will spin, no unit will experience magnetic flux interference, and the actual GPS coordinates of any waypoint will be taken very close to where an underwater feature is seen. The bow transducers and GPS antenna are together, and the console units use a stern GPS antenna very close to the transom transducers. This makes returning to a waypoint very accurate, even if stored by one unit but returned to with a different unit.
That's an interesting suggestion. Thanks for your suggestion. Most of my customers are bass boats, where most if not all fishing is done from the bow, and prefer to use one GPS antenna placed on the bow for both coordinates and for heading. This is critical for marking waypoints like beds.
The Point-1 has a +/- 3 degrees of accuracy on positioning, placing the Point-1 at the stern of the boat creates too large of a position error. Also, the Point-1 is a 32 channel GPS receiver, this gives a positional accuracy of 3 m (9.8 ft.) while the built-in GPS on the Live unit is 16 channels with 20m RMS accuracy. So for this reason it is preferred to use the Point-1 for coordinates.
I ran a similar configuration that you suggested except I used a GPS antenna (Point-1 without heading) on the stern for the console units and a Point-1 on the bow for the bow units. When I marked a waypoint on the console it was consistently 20 ft off on the waypoint. Since switching back to all units using one GPS source that is not an issue.
And yes, I originally thought that it made more sense to use the antenna closest to the transducer but for me and the way that I utilized the waypoints, it was consistently incorrect. What I would like would be to "configure" the boat to designate both the antenna location(s) and transducer location(s). Then the coordinate would be offset based on the antenna and transducer used for waypoint creation.
Good video Garry
Thank you!
