So what’s the latest - prefer free or maybe a one time charge. Need to be able to cache areas for offline use. Any suggestions?
Navionics or whatever the updated name is. I think for my IPAD it was $30 or 35. You can download areas, and use it offline. It gives depths and contours, you can save spots, input coordinates for reefs. Moving map display, pretty useful. I think boats need to head in the same direction as autos where the display in the boat mirrors your mobile device via Bluetooth. The downside is trying to use a portable device on the water, in motion, with glare and small size of device, you still need a sonar too.
I’m not 100% positive but app should work regardless of cel signal strength because it’s using gps function in phone....
