best GPS for map/chart & compass users

The eTrex 10 has the same GPS receiver as the costly 20 and 30, without maps. If you can read the B&W screen, the 10 is perfect.

Its reliable, tough, and waterproof. Lithium AAs, 60+ hrs and not exhaust the batteries, GPS+WAAS+GLONASS on. With NiMH rechargeables, 33 hrs, 41 hours with GPS ON only. B&W screen is great in bright sun, backlit OK in darkness, color versions hard to see in sunlight but best when backlit. You can rearrange menus to suit for fastest use. GLONASS ON locks faster in canyons and cities, and realizes best accuracy, 6', when GPS only struggles. I use only tracking and backtracking, marking waypoints, generate UTM/UPS grid references for map & compass; you can set most any map datum known even non-USA maps. I do all housekeeping on PC with BaseCamp, links without bugs, then easy port to Google Maps for detailed terrain & track analysis: confirm distances, time, etc., the 10 reports.

Button+ joystick good for gloved, wet or dirty hands. Wash unit clean but makes cumbersome to set routes or ID tracks, also small screen very cramped; best to set routes via PC, only use eTrex interface for emergency. On eTrex 20, 1:24K topo maps not enough detail versus paper map or large tablet map. Why pay $100+ for Garmin maps or struggle installing free raster maps when viewing window only size of business card? Free maps slow to scroll, slower still to zoom in. I think eTrex line too small for maps.

Main con is more features than full manual details. Took 1 week of study before used in the field. Dropped many times into dirt and 3' of water to test toughness. Joystick can activate unit if place in pocket, best to use carabiner clip, belt clip breaks at hinge with rough use or age. Over 200 hrs of field use.

Just a tad more polishing to be perfect

The other reviews here sum up the big downside to this device: It's manual is really inadequate. I knew this buying one, but I was on my way to an unfamiliar area and wanted something to find my way back home should I get lost. I had literally no more than 5 minutes at the trailhead to install batteries (not included, had some in the car thankfully) and learn the device and get on the trail. Overall, I found it amazingly easy to use, having never used or owned a GPS product of any brand before. It kept track of my trail over two days over 18 miles, and the tracks and waypoints load right into google earth. I just left things at default that weren't described in the quickstart manual. Because it's waterproof, it dealt fine with sweat accumulation in my pocket. Why was it in my pocket? Because it didn't come with a belt clip or anything that I could attach it to my pack, not even a $0.25 lanyard. But, hey, you can buy a clip online for $10 or whatever. The biggest issue I dealt with while on the trail and it being in my pocket is the thumbstick would get occasionally pressed a couple times, and it would set a 'go-to' point that didn't have an obvious way to be removed. After futzing with it at a break, menu->"Where to?" -> "Stop Navigating" was the solution. Overall, for what it costs, and what it does for what I want, I give it 4/5, just because of the lack of belt clip or lanyard that really only would cost $0.25 to include and a manual that could suck a little less.

A good little device

I use this for hiking and backpacking. It took a few trips to REALLY figure this thing out because there are no detailed instructions, but I found it easy to learn. So far every trail I have used this I know very well so i mostly use the device for stats like speed, distance, elevation and stuff like that which i like knowing, especially while backpacking. It can be a little slow at times but not often. It seems to get really good battery life. I've been using it a lot and have only had to change the batteris once. Be warned, if your looking for something to use in place of a map and compass, this is not it. It works best being used alongside a map and compass.

way better than the venture hc

others have said that it's hard to use and I couldn't disagree more. I got this as a replacment for a Garmin Venture hc and it's so much better. I had the Venture for years and never really figured it out while I had this out of the box, loaded a .gpx track on it, mounted it on my bike and was riding in half and hour. it's simple enough to use the different functions while riding and took a solid hit when I end-o-ed my bike. It's also easy to get your tracks off of to review on the computer or strava

Solid Navigation, Realistic Price Tag

Base Map is accurate but lacks a detailed graphical representation. This product is best used as a supplement to a map and compass.

Owners manual and quick start guide seem incomplete. I downloaded the full owners manual from Garmin's web site and even then there were a few features that were not covered. However, I was able to determine how they worked with a little experimentation.

Good For Novices

I don't know if its because this is my first GPS or if it's really this hard to get used to but I find it really confusing. I've gotten the ins and outs to a point. It is very accurate, and is able to get Geocaching maps but no extra maps beyond that. Over all its good for beginners imo

GARMIN eTrex 10 GPS by Garmin

I bought this to use on my boat to replace my knotmeter. Great performance at a reasonable cost.
Built in compass is great for boating. Allows you to reconfigure screens to show parameters which matter to you. Long battery life. Easy to read in sunlight.

The Military Standard

I used last year's model in Afghanistan fighting the Taliban. More effective and compact than anything in the U.S. military. In fact, they issued us this product for use in ground combat. Wouldn't deploy again without it, or one like it.

I can seek clearly now

We use the Garmin eTrex 10 for geocaching. It is the second model of GPS we have tried and it is the one we will keep. It is "user-friendly" and suits our needs perfectly (we're finding caches!).
Tebah at Eastern Mountain Sports (EMS) on 01/01/2012

Pleased with this entry into Geocaching

For an entry level unit it can be beat in price; but comparing with other units it offers much more. Will be using it for my son's Scout Troop, and it promises to be ideal.

Negative Reviews:


You'll get a better user's manual with a pair of socks. The on-line version isn't much better. I am a long time user of GPS's, I have 4 on my boat and all have decent manuals. Without the knowledge of how to use, this thing is pretty useless. If a REI store were closer I'd have taken it back after one use but I have finally figured out how to do the one thing I really need, make a track. Might be a good piece of gear but I doubt if I'll ever know.
Oldsampeabody at REI on 03/03/2012

might be O.K. but who knows

Garmin paid me, their customer, a great compliment by believing I could use this GPS with almost no instructions. After five hikes I have figured out how to make and follow a track. I don't know, yet, how to name a route or how to do much else that the GPS is supposed to do. I am an old time GPS user, this is my sixth,but I am very frustrated and dissapointed. With out a good user's manual any GPS is pretty much usless.
Oldsampeabody at REI on 03/03/2012

It's all greek to me!

If I spend good money on a product the instructions should be clear and total enough that I could learn to use the device myself by following step by step instructions. The instructions included were so minimal that a class is required. More money! There should be more written info included or a website to visit to teach ourselves how to use it.

The back is hard to undo

I couldn't get the back off to put in the batteries, so I am exchanging it for another one.
