I'm interested in getting a GPS watch to use while hiking. I know it's not something I need, I just think it would interesting to see how much distance I've covered/have left to cover while hiking. The main concern I have is battery life. Most GPS watches have to be recharged daily when being used in GPS mode, right? I sometimes hike for a week at a time, so this would be an issue. Anyone else use a gps watch for multi day trips? Suggestions? Thanks!

I use a Garmin Forerunner 305. It lasts about 2 full days (8:00 am to 4-5 pm) and poops out about halfway through the 3rd day. My 1st year sectioning I just used it while it lasted. The 2nd year I spent my 1st night at Walasi-Yi (Mountain Crossings in Georgia) and recharged it; getting 1 extra day of use. Last year a friend who also has a Garmin went with and we used his for the 1st couple days then mine, and recharged overnight at Nantahala Outdoor Center. So look for a hostel about midway through your hike and you'll be good to go!

Happy hiking!! Ickybod

I had heard that GPS watches aren't as accurate and don't lock on as quickly as handheld units. Something about the small antenna.

Is this wrong?

Is this wrong? Yep. My garmin Foretrex watch GPS is by far the most accurate GPS unit I've owned. It will last about 16 hours, maybe two days of hiking on a fresh set of Lithium batteries.

I can't compare with a handheld device, but accuracy is perfect. I run with my Garmin 305 (it is a runner's watch) and it is right on the money with distances over known courses. It takes less a minute to lock on to a signal when I turn it on, in my neighborhood or in the woods.

Thanks for the update. It's always a good thing when I can find that one of my preconcieved notions were wrong.

Yep, battery time will be the biggest problem. My 405 might last 1.5 days. They will charge via USB though if you plan on having some kind of USB battery pack.

The newish Garmin Fenix is supposed to record for 50 hours on a charge.

You could also use a smart phone (like an Android running MyTracks), but you might get 8-10 hours, depending on the phone, so worse than a watch.

By the way, the Foretrex 401 uses two AAA batteries, no recharging required, just swap 'em out. I would think 4 sets of two, 8 total batteries would last 1 week of hiking, as long as you diligently turn the thing off at camp; easy to forget to do! I wish it had a "time-out" power saving feature, like if it detects you haven't moved in a couple hours, it would turn itself off. The 401 does not do this. Anyway, nice little watch-GPS. I basically use the odometer feature, and occasionally navigate with it. The cheaper 301 has the same features as the 401, but without a separate barometric altimeter.

+1 for a Foretrex. Mine is a 301. Used it a lot. Normally, I keep it off when I hike. This past summer, I kept it on while on a Boy Scout Canoe trip in Bisset, Canada to see how far we paddled/portaged each day. I seem to recall the batteries lasting about 2 1/2 days or so. Plug in some new ones and off you went.

I am using Polar FT1. It was my first GPS watch which was gifted by my father. Still it's working perfectly and it shows accurate details.

They may have improved since then - the antennas have gone several improvements since the early 315.

Couple of questions:

1) Can you do the turn it on getting a reading on your location, turn it off hour later turn it back on for a few minutes to extend the batteries?

2) Are the batteries easily replaceable? E.g. could you buy a set or two of extra batteries and recharge all the sets in town and then have battery life for 6 days instead of 2.

Not sure about the 305, but the Garmin Fortrex 301/401 series use two AAA batteries, obviously easily replaceable and fairly light to carry many extras. And yes, for maximum life, turn it off when not using it... it only takes a couple minutes to turn on and lock on to the GPS birds. Turned on all the time I get about 15 hours, nearly two days of hiking per set.

Be careful though... the initial lock is sometimes sketchy, give it enough time to lock on well (3 minutes?). Make sure you have a relatively clear view to the south-ish. Light tree cover is fine, but very dense forest or a large rock outcropping just to the south of you can block the coverage.

I always turn it on when we start to hike. In a minute or so, it has satellite lock and away we go. As soon as we start hiking I turn on the tripmeter then turn off (turn off the tripmeter) at breaks and at the end of the day. I power down the watch when we get to our next camp for the evening. There is some mapping technology on the watch that I've never used, or even bothered to figure out. After all it is primarily a running watch. As far as the batteries go...there are none. It is rechargeable and sits in a small cradle attached to a cord to a wall outlet. So if you come across some electricity during your hike you can charge it up. Sorry about the lack of paragraphs in my answer. For some reason my computer doesn't respond to the 'enter' key to start a new paragraph on WB. Happy Hiking!! Ickybod

I have the Garmin Fenix. With the full GPS turned on, the battery last only a day; however, it doesn't take much to recharge it. For multi-day hikes, I take a Flash Charger along. One Flash Charger will keep the Fenix going for a week or more. http://www.nomorerack.com/daily_deals/view/525339-2_pack__2600mah_flash_chargers_for_mobile_devices_ __assorted_colors
