jp0212 Report post Posted December 9, 2016 Cell phone apps have pretty much replaced handheld GPS. Screen quality and functionality is way better on a smartphone. Most apps allow maps to be downloaded to be used without cell signal. Biggest hurdle is battery life on your phone To handle the battery life hurdle, I carry a portable charging device and cable. I'm able to fully charge my phone from dead to 100% 3x. It has 10000mAh. Also, make sure you're on airplane mode while out there to lessen the drain on the battery. GPS works on airplane mode. Same here. I have the Photive Bolt that has 9000mAh to charge all my devices. It's drop proof and water resistant, and was only $40 on Amazon. I would like to pick up one of the Dark Energy units though. Slightly more power, seems more rugged and they are a hunting based company that I would like to support.

Allforelk Report post Posted December 9, 2016 I have a 20,000 mha battery with built in photo voltaic charger. I leave on the dash in cold weather and have yet to run it all the way down. I can charge my phone and steri pen at night and I'm good to go by morning. Share this post Link to post Share on other sites
forepaw Report post Posted February 28, 2020 Howdy CWT amigos, I just upgraded my android phone, and am considering keeping the old one strictly for navigation using On-X or something similar. I plan to use the new phone for Avenza maps, and keep the old one just for GPS, since it doesn't have a SIM card, and won't do anything without wifi. But I should be able to put in a memory card and download On-X maps and use as a GPS, since that doesn't require wifi or mobile network, only open sky - or am I missing something? I also have a Garmin GPS, but thought it would be really neat to salvage the old phone for use with On-X. Appreciate help from all the phone and GPS gurus on this forum. forepaw Share this post Link to post Share on other sites
CatfishKev Report post Posted February 28, 2020 Steve, you should be able to download onx on the old phone at home with wifi. Any areas you want to have on that phone you have to download that area for. Just having onx wont work unless you do this. Then in onx you switch to airplane mode. Doing onx on a back up phone is a good idea. I've found when I have map downloads on my regular cell it would make my phone kind of glitchy so I would only do it right before a hunt. Btw, you can also do the same thing on a tablet to. I do that before kids hunts and just keep it in the hunting rig. 1 Share this post Link to post Share on other sites

recurveman Report post Posted February 28, 2020 I just use one phone and download ON-X maps and done. Not sure there would be an advantage to using two phones instead of one. No need to over think this one. Share this post Link to post Share on other sites
