For several years I've used a Garmin Dakota that I bought on big sale at Bass Pro. Wanted that for weather proof use. Had a ram mount for it too. Worked great. I mainly use it for viewing location on maps and tracking rides. With lithium ion batteries this thing will run for days!
For maps I've used MapTiler Desktop free (also an ios version but haven't used that) to locate printable paper maps on Google Earth coordinates. Not a very intuitive software but works well. Locate the scanned paper map on google earth, export as kmz file, copy to SD card in Garmin under Custom Maps folder. Then you are able to see your GPS location on the paper map! This is not a navigating map but still, you can find your location.
For phone users, Maplets works well and Avenza for free MVU maps of all national forests.
