Hi, I've managed to create a .at5 file from sonar logs from my Elite 5 HDI, using Reefmaster and IMC, but it doesn't work. I'm obviously using the wrong settings, so my question is;
Is there a list anywhere of basic settings to use with different chartplotters, Or do I keep using trial and error?

Also I downloaded Anglingcharts' trial .at5 file and that works fine on my chartplotter. I noticed that he'd created it using Atlas6 in IMC, but IMC seems to default to Atlas12 when using it with Reefmaster, whatever settings i put in.

I think that Atlas 12 *should* work on an Elite HDI (but not on an Elite non-HDI). I could be wrong though. You could try exporting with Atlas 10, which is an option in the AT5 section of the "write to File" export, but is not available when exporting in a preset style direct from the project (this always defaults to Atlas 12).
What kind of map are you exporting? Can you provide a screen shot of your contour map, just to rule out other possible issues that might be preventing your map from showing?

Hi, thank's for the quick reply, I've been using the different preset styles, as I'm only using the trial version at the moment.

That's a raster map background with contours. Which style were you exporting? If you want to send your .rmdb project file to This email address is being protected from spambots. You need JavaScript enabled to view it. I can export the map for you in a range of styles so that you can test it.

Finally got it to work, not quite sure what I did, but I exported it as an AT5 map with flat raster background. Thanks for your help.
