Point_1_Install.jpg

You can see in the picture where my Point 1 is installed. It has no problem seeing the satellites as I use the Point 1 as the GPS source on my console-mounted Carbon 12 and my bow-mounted Carbon 9. My GPS position on my charts is fine never had a problem there.

This install location is pretty common.

The internal compass of the Point 1 is what provides heading data. The compass of course is a magnetic device no different than any other compass you are used to. As long as the placement of the antenna is not in a place that has magnetic interference (RFI, EMI) it will work. The compass does not require a view of the sky just that is is level and the "arrow" on the antenna is aligned forward when installed. I have the Point 1 selected as the data source for heading on both units. This is how all my previous boats were setup and they all worked as intended. This is also how Roy Barrow instructed to setup the Point 1 when I took his Lowrance class years ago... Roy is the man when it comes to Lowrance!

I have checked best I can for magnetic interference I use a handheld compass and cannot see any obvious interference.

To clarify: my heading (meaning which direction the chevron icon that represents the boat on a Lowrance chart is pointed) is correct and usable when the boat is in motion while powered by the outboard or TM. When I am fishing and neither the outboard nor TM are moving the boat, the boat icon on my chart does not point in the correct direction it can be 180 degrees out or 90 degrees out or 10 degrees out.

I have talked to Lowrance level 2 tech support twice now while on the water. They cannot find anything wrong with my software settings that would cause my problem. They are in the process of calibrating a new Point 1 before it ships to me. I will install their pre-calibrated unit and see if that fixes the heading issue.

Does anyone know what is causing lack of usable heading data while my boat is not in motion?
