I picked up a Zoleo for my June Quetico trip with my son.  First time using such a device, but it worked well enough. The Zoleo has no screen, so you have to pair it with your phone, but that worked well for typing.  Messages take a while to send an receive, so it's not exactly like texting.  It was nice to check in with the wife each night and make sure things were in order at home. I'm still undecided on the weather feature, if it is more or less accurate than my 10 day printed wunderground report I prepare the day we leave. 

For navigation I take a map and use my Lowrance Hook 4 with a custom made digital bathymetry map with sat imagery.  I actually left my Garmin at home this year as I did not plan on doing any bushwhacking and was more interested in where I was on the water and looking for fish.  That reminds me, I need to upload my sonar logs to CMAP, now that their website is back online(was down since June due to a hack.)
