So to save battery drain, you download and save the maps ahead of time and then run in airplane mode. Does the GPS still know your specific location even in airplane mode? No cell signal needed to know where you are?
Yes, you can run in airplane mode to save battery. Might also prevent your phone from ringing as you draw down on an animal.
I experimented with mine last night and also determined that it will work when the battery saver mode is on.
Backcountry Navigator would require a separate purchase for each of my devices?
I don't know the answer to that. :confused:
When downloading maps are you able to zoom in closer while in the field of do you just see as it displayed when you downloaded it? How large of an area can you see in detail?
You open a map source and then select the area you want to download. Once it is downloaded you can zoom in and out and obtain the same resolution you would have if you were online.
The size of an area that you can see in detail seems to depend on the map source. Some have higher resolution than others.
Last night I downloaded a small area in the neighborhood and then drove to my grandsons football practice all the while recording a track. The two screen shots below are of the same downloaded map with one zoomed in. The red lines are my out and back track.
Today I downloaded a topo map of the same general area. When it is opened it shows the track also. If I had recorded any waypoints they would also show up. Below are screen shots of the topo map,
There are quite a few map sources available for free download. I have not looked at all of them as of yet.
Below is another screen shot of an area I might hunt this coming weekend. Here you have aerial photo with topo lines overlayed on it.
