I bought the navionics app for my phone. Works really well.
Unfortunately they don't have that for android
What don't they have for android?
what app is that on your phone?
Navtronics. Here is a close up of bass.
I have a hand held Garmin as well, which I never use. But "HT" did bring up a point. Navionics is great, but it will drain your battery.
Good point about the phones, but wouldn't a garmin come with a service charge or a plan to pay for monthly?
Yep, phones aren't supposed to be hanging out in below-freezing temps either. If you're gonna use your phone, I would use it sparingly and keep it warm. The cold will only increase how hard your phone has to work and the battery will only get worse. Just something to think about.
I never have any issues with it draining my phone battery. But I never fish HUGE lakes either. So I guess it just depends on the application! I also put my phone in a ziploc baggie whenever I'm fishing.
I may use the nav. apt. on my phone or tab.to get me in the general location but it doesn't always work and might be off some times by 100' or more its just not accurate enough in some locations depends on cell coverage my garmin has not let me down yet that's why I made the upgrade this year.
