I would very much like to share this optimism, but I cannot.

Traces of the GPSMAP 64s (yellow), GPSMAP 65s (magenta) and GPSMAP 66sr (cyan) taken on three different days:

The GPSMAP 64s clearly struggles at times:

Thanks to @mimichris, I had the opportunity to repeat one of my earlier tests with a current CPE.BIN on both the 65s and 66sr:

I wonder how well a high end smartphone would perform in the forest. Did anyone compare say a Pixel 6 with a 66sr yet?

I sometimes use Locus as software on my MI9 Xiaomi, multiband, but the track is not very nice, less nice than the 66sr, I think the management of GPS on a smartphone is not optimized like on a real GPS hiking.
GPSMAP66sr, GPSMAP67, GPSII+, Twonav Cross.
