    Garmin Foretrex 401 GPS is rated 4.7273 out of 5 by 11.
    Rated 5 out of 5 by from Does what is stated I use this daily for cycle training and for hiking. I've read some comment about slow to catch Sat. signal but mine grabs 6 in around 90 seconds from power-up and I live near tall buildings and tons of trees. Con:maps? According to the description of what the unit provides "maps" is NOT one of them. GPS waas battery life is triple the life of my other expensive GPS units. I just use common copper-top AAA's which I trickle recharge 2 times each. Compass works ok and if you can move 2 meters the GPS picks up any slack in direction finding. Altimeter is more than accurate enough for training and accurate enough for navigation unless you're surveying a new train route through the Himalayas. Sunrise/Sunset is handy to keep you legal in the field and on city streets. Barometer is handy for cross country planning or huddled in the snow wondering if it's blowing over or more is coming in. You can also upload routes to the watch using 3rd party free software with just a few simple clicks of the mouse. Garmin Connect is a must to pinpoint your weaknesses and customize your training to target them or to just visually track your progress in general. Rain proof. I use this approx. 300 days a year, rain, snow and blazing sun. The screen is slightly recessed which protects it. The only thing I wish was a couple button pushes less is the "reset trip data". Other than that I really like this unit and for the $ it's a heck of a deal.

    Rated 5 out of 5 by from 4 times more accurate than Iphone app. I love this GPS, I own others but use this one the most, the wrist top setup is so much better than use both hands, I can use it without letting go of my trekking poles. I tested the 401 with an forerunner 610 an Iphone and android. accuracy was within: Foretrex 401 12 to 20ft. Etrex 20 12 to 20ft. Forerunner 610 30ft. Iphone bounced between 60 and 100 ft. Android was not much better than Iphone

    Rated 5 out of 5 by from Garmin 401 A very useful piece of kit that will compliment a casual user or experienced navigator. A map - if you're in need - is handy because of the lack of base maps... But if you are just looking for a basic her to there, easy to use GPS without the un-needed bells and whistles you can look no further.

    Rated 5 out of 5 by from Great for the money Fun and easy to use. Straps to your wrist so you don't have to find a pocket for it. Has a good battery life and runs on two AAA batteries. So easy a Marine can use it.

    Rated 4 out of 5 by from Love it! I love this gizmo! I workout outside each day - mostly kayaking. The 401 is my constant training partner. The tracking function is super handy in helping me find my way home through the Florida swamps and forests. The waterproofing may not be 100%. I had a 301 but it leaked while kayaking rolling/kayak surfing. Under more normal use - raining for example - I feel very confident in the waterproofing. The multiple functions far exceed my needs. This tiny unit is perfect in recording your travel information. Double thumbs up.

    Rated 5 out of 5 by from My Favorite GPS System I have been using the Garmin Foretrex 401 extensively over the course of three years, primarily for hiking and backpacking. It has endured years of dirt, sweat, water, and mud, and it keeps on working. See the attached photo of me using the Foretrex during a Zombie obstacle course mud run. It survived. I did not. And neither did my HTC phone I forgot in my pocket. :-) It has finally begun to show some minor signs of rust near the battery terminals, most likely due to moisture introduced by me changing out batteries with sweaty hands, etc. However, if and when it does fail, I will buy it again without any hesitation. My primary purchase decision points were weatherproofness, durablility, size, weight, and the fact I could wear it on my wrist. It has been with me on so many adventures, and it has not let me down. In fact, this device has helped me out of some really tough jams. Like any GPS technology, there is a learning curve. But that's really just the nature of orienteering. The device itself is actually pretty simple, but you really do need to understand how to use the tool before putting yourself in any tough situation. I would advise anyone to take a GPS navigational class. I did not, and it took me a while to really figure things out. Lots of reading and experimentation. You do not get any topographic views like larger units, but I always carry maps, and suppliment them with my GPS. If I have reliable track data from a trusted source, I install them before my trip so I can navigate efficiently. But often times, I end up just creating my own desired paths and waypoints, and it's always a ton of fun reaching destinations with the help of my Foretrex. Even if I go on last minute trips without preloaded tracks, I am confident that I can always find my way back. As soon as I turn it on, I typically calibrate the compass, clear any previous track and trip data, and create a brand new waypoint of my starting position. The device will keep an accurate log of where I've been, and I just add waypoints for each point of interest and trail intersection along the way. When I am ready to return, I use the track back feature which gives me pretty accurate ETA info. Where I find it lacking is the rather short number of characters I can use in the names of saved waypoints and tracks. The number of saved tracks is also fairly limited. The most frustrating limitation that plagues so many of Garmin devices I've researched is the number of track points, or breadcrumbs, that you can import in a single track. It's only about 500 trackpoints! If you try to import a saved track that has more than that, it truncates the entire track, so you must first simplify the track data before the import to avoid that problem. Irritating, but again, this is not a problem isolated to the Garmin Foretrex 401. I highly recommend this unit. Have fun and be safe!

    Rated 5 out of 5 by from Near Perfect! I've used this for over a year now on Backpacking and Hunting trips, It works fast and is very reliable. If I could improve this I would make the Time font a little bigger/ easier to read on the go.

    Rated 4 out of 5 by from Everything you need on your wrist Fantastic for ultra trail runs above 20 hours. No other wristop GPS can give you such accuracy for extra long distances. It only takes to carry spare batteries and you're ready to go
