I have a Nav 5 that I will be lending to my daughter when she goes on an overnight hike.
She has a PLB that will transmit a distress call and her location in the event of an emergency but I thought a handheld GPS might come in handy if for some reason they need to establish their location.
She is 34 years old but any of you with adult children will understand my not being able to fully let go.

My questions are -
1) How long would a fully charged Nav 5 battery last if it was handheld, turned on and in use ie screen lit up.
2) And how long in standby mode?
3) Does anyone have any experience in using the Nav 5 as a handheld device?

Re: Nav 5 battery time*

For something simple like just being gone overnight the 5 will probably be find however battery life is just a few hours generally. If she does this more often I would suggest you or she find someone with a Garmin Montana she can borrow. It has much more accurate information for topography (back country hiking) and the battery will last significantly longer.

Don't know but it might be important to know how old the battery in it is. I replaced mine recently and it holds a charge much better than the original. Cell phone won't work for her? Nav V seems kind of bulky for that purpose.

You wouldn't bet your life on cell phone coverage in remote areas of Australia.

It wouldn't be 'cell phone coverage' per se as in cellular service, it would be a case of downloading that section of the map that you're going to be in so the GPS chip in the phone will still work for navigation.

If she agrees that the Nav V is worth taking, then maybe it's worth taking a backup battery and USB cable to recharge it. But...

I've been backpacking for well over 25 years all over the world and you couldn't pay me to hump a GPS the size and weight of a Nav V around in my pack. Especially one that has maps which cover roads and not hiking trails. Since it's unlikely that your daughter will want to watch her progress on the screen when trails aren't represented, battery life shouldn't really matter, since she might only turn it on when needed. if it's only "to establish their location" I agree with others that any cellphone will do, even without signal. But knowing where you are and turning that into help to get yourself get where you want to go are two different things. So unless you can somehow set up the Nav V to show topo maps, honestly, a paper map, compass, and some basic skills are a far better option than carrying a heavy GPS.

I think he means using a cell phone as a GPS navigation device. With maps loaded it should perform as well as Nav 5 with less bulk and no dependency on mobile coverage

Thanks for teaching an old dog a new trick. I've been Googling it to find out more.
When my tech savvy son dropped in this afternoon I asked him if he knew of such a thing. He didn't. So as the expert in the room I told him about it.
