[TG] [TG11] Axiom Pro 9 Livemapping Issues

[Tom - Raymarine - Moderator]

Hello Randy,

There's a practical limit (in processing power and memory) to the amount of SonarChart Live data that the display can and still give a fast update rate. The way the displays handle having very large amounts of SCL data is draw the original, key Navionics chart data (important for navigation) first and then add the supplemental SCL overlay in tiled squares later, as processing and memory requirements allow. This is generally only a problem in systems that do have very large amounts of SCL personal bathymetry data. There isn't really any way round it being slow to redraw that large amount of data, that's not a Raymarine issue as such but a normal characteristic of computer graphics processing (it takes more effort to redraw a complex scene than a simple one), but what you can do is reduce the amount of data to redraw.

The recommended way to reduce the amount of data to redraw and speed up the display is to upload your sonar logs to Navionics on a regular basis, when you do an online chart update. Navionics will then include your logged data into future chart updates (which both you and other boaters can take advantage of) in an optimised format which will still give high resolution and detail, but which will be fast for the display to redraw. You can then remove your personal SCL data (make very sure to not remove any Navionics chart files!) from the card. This has the additional advantage that it backs up your sonar logs so that they won't be lost in the instance of a chart card problem down the line, whereas at present if you have a problem with the card then you lose everything.

You are correct that a-Series displays can't be updated to LH3: this is because LH2 R19 is already pushing the limits of that hardware (a-Series has less memory and a less-powerful processor than eS-series) and we couldn't get the more advanced LH3 to run properly on a-Series hardware without cutting out key features.

Regards,
Tom
