Cardinal rose, declination diagram, grid squares?

Hi everyone,

I use CalTopo for hiking and hunting and love it, for safety and because sometimes I like to be old school I always carry a compass and protractor with me. But, I find it difficult to use with the printed Cal Topo maps, since the scale is not always clear and there is no declination diagram.

Is there any way to add a true/magnetic north icon, declination information, or scale to the map? This way I can navigate with a compass efficiently, especially if I get tired and need to use dead reckoning. Alternatively anyway to add MGRS grid overlay?

Note: My typical overlay is Google satellite as base layer and the USGS 7.5 topo map at ~15% opacity, this is for hunting, for hiking I don't use any satellite imagery.

I Appreciate all the help!

    PDFs generated from CalTopo (Print -> Print to PDF) include a scale bar and declination arrow at the bottom of the map, plus the option for an MGRS grid. You can't include satellite imagery with Google's level of detail, but you can add the NAIP Imagery layer.

    Since you're using google satellite, I assume you're generating a screenshot or using your browser to print directly from the map viewer, in which case there's no way to get any of those added.
