Recycling an Android Phone As a Handheld GPS?
imblum writes "So my dad's antique handheld GPS unit just went toes up and I was considering replacing it for him with an old Android Smartphone. All he really needs it for is hunting and camping (no navigation), so I don't want to pay for cell or data service. I found the program Mobile Atlas Creator to download map files onto the SD card, and an app called Maverick Lite to view them. Now all I need is to decide on an Android phone. I was considering a Samsung Behold II ($100-200 on Craigslist), but thought it would be nice to get some input from the Slashdot community. It seems like I can get a lot more functionality for the money out of an old Android than I could from a big name handheld GPS. Does this plan sound reasonable? Is there anything I'm overlooking?"
It might not be a good idea for multi-day hikes, but you can probably get reasonable single-day battery life out of many or most models. Particularly if you power off the other radios, and if you can power off the unit itself when it's not being actively used.
As to why this and not a dedicated GPS unit - sure, a dedicated unit will probably have better battery life, and it might be better for GPS usage in other ways as well. But it's almost certainly less flexible. I can really only use it for GPS - what if I also want to take pictures or make notes about each location I'm at? Sure, I could carry more dedicated devices to handle those functions. But at some point, isn't it worth carrying one device which can serve several functions while fitting in my pocket? Also, a dedicated device probably comes with the software package that it comes with. Adapting a smartphone means that you're running a mobile computing platform which just happens to have a GPS sensor - you can probably pick among several options for the software, or even program your own. Some smartphones also have additional sensors like accelerometers or compasses which could improve the functionality - not all, of course, but potentially valuable if you can get it. Maybe some dedicated GPS units have this as well, but I doubt that the really cheap ones do.
For the subby, the situation they describe really does make it sound like a dedicated unit is at least worth a serious look. A dedicated unit is more likely to "just work" and that's likely all the guy wants.
