Garmins GPSMap 64s vs 60Csx (3 Viewers)

[Saxatilis]

Hello
since 2009 I am owner of a trusty Garmin GPSmap 60Csx.
A couple of years ago after intensively using it for perimetering the boundaries of a protected bird area I noticed a bit of difficult in finding and keeping the signal under the broadleaved woods.
I wonder if the newer GPSMap 64 series has been so improved that can I evaluate to change it sooner or later.
Has anyone experienced this new or compared both devices from garmin?
Thank you
Luca

I have been using the 64s in the forests of Finland for two bird counting seasons now (summers 2014 and 2015) with good results. Before that I was using Colorado 300. It seems that the 64s gives a bit more accurate and stable coordinates due to its dual satellites (GPS + GLONASS), especially in the northern latitudes. However, it might be wise to delay updating until 2019 when the European satellites system (with their unprecedented 1m accuracy for ordinary users) should be fully functional.
