For years (decades) I have used my trusty little Garmin etrex CX GPS as a speedometer and breadcrumb generator when paddling rivers and the BWCA. Alas, it got dunked on the last BWCA trip and now its display appears to be caput.
I would prefer to replace this device with a modern equivalent. That is, a standalone, offline GPS with internal maps; a unit that can be charged from my power bank, not running on batteries. Such a device doesn't appear to be offered by Garmin or anyone else. So, it looks like from here on out, I need to use my phone and a GPS/map app.
I have a newer iPhone and I was surprised at the battery life on my last BWCA trip, so maybe a GPS app will not drain my phone as much as I have feared. I see several IOS GPS/map apps out there: Gaia GPS, onX Backcountry, Avenza Maps, Topo Maps+, and others. I will not be using it for navigation. I prefer to rely on paper maps for that. I do want to continue being able to watch our speed and occasionally check the GPS against where I think we are on the paper map.
Can anyone share their experience using these GPS phone apps in the BWCA?
