The REI Member Dividend

The REI dividend is a unique benefit of membership in the REI co-op. It's comprised of your member refund—typically 10% back on eligible purchases—and/or your REI Visa® card rebates.

Each March, active REI members and REI Visa cardholders who earned a rebate receive a refund in the form of an annual dividend notice.

Only active members receive annual dividend notices. To maintain your active status as an REI member, you need to make net merchandise or shipping purchases of at least $10 per year, unless you joined that year. Member numbers are issued in one name and only that person receives the member refund. Your number can be used by others in your family, but it cannot be transferred to someone else.

by fromGps The etrex 20 is a very hard to use. The direction are not easy to follow and I would not recommend the device for people who are not really tech savvy. I had several people try to help me use it even store personnel and each one had trouble using the device. Wanted to use for an Appalachain Trail hike. Put in way points however when I tried to use it on the trail the only thing it did well was tell time. With the extra batteries I had to carry for the trip it was extra weight I did not need to carry. I do not recommend them.

by fromNeeds software improvements Primarily bought this unit for Geocaching. It worked great first couple weeks I used it then there was a software update to the unit. (firmware 2.30) that essentially made the unit useless to use for geocaching. It works great as a GPS but to load geocaching query's to this unit it can only handle a few. Tech support is aware of issue and is working on a fix. Until then I consider this unit a paper weight.

by fromnot of much value You can make waypoints, which get you back to where you started. But, if you expect anything more than that, you'll be dissappointed. There seem to be other features, but they're not of much value. You can save ALL your waypoints i.e. Utah, Calif., and only delete ALL of them. This device is more of a novelty or toy for a youngster who has outgrown walkie-talkies. I'm not convinced it's very accurate. We'll see. I've taken it to Utah - all over, and the San Gabriel Mtns. It's really confusing. the salesman should have cautioned me rather than to tout how great it was, but then that's some salemen.

by fromhaving trouble with the device purchased for a back country trek and was unable to use since: 1- It does not come with full instructions. 2 - the maps would not download for 2 weeks because of a "glitch" per Garmin in the software. Not the easiest gizmo to work with. The display is decent but small and not very good in bright sunlight. Honestly haven't had a chance to use it a lot, but until I can use it more proficiently, I'll give it an average score

by fromComplex , Expensive , lots of trails missing The GPS is helpful if you get totally lost and need to get back to your starting point but I took a test drive to El Cerrito and didn't see the trail names ..etc marked well. Ended up loosing the trail as soon as we hit some roads. I didn't buy the topo bundle. Maybe I'm expecting too much - we are getting attached to the ease of use of the PDAs and this GPS feels too primitive and bothersome to use. I will probably stick to my paper topo maps.

by from"Bricked" in less than a week This is my first handheld GPS, and I really want to like it. Overall it performed well during the short time I was able to use it. Unfortunately, a faulty firmware update rendered it useless. My local REI is out of stock, and Garmin has a 2-3 week turnaround for replacement (plus they won't pay for return shipping). Garmin really needs to work on their firmare updates and customer service in general. The least they could do is offer to pay for to return shipping. Although I'll get a replacement, I'll be nervous the next time I update the firmware.

by fromNot Bad! I am an ex Scoutmaster with allot of back packing experience (over 10-years ago). I recently started power walking in the neighborhood and plan to start day hiking in the next few months. I bought the eTrex 20 for several reasons. First, I needed a pedometer, but experience has taught me that pedometers are not accurate. Secondly, I wanted to track my speed and, finally, I wanted to be able to use it when I start hiking again. At this point I can only give it a qualified recommendation. Since I have only used it for power walking in my neighborhood so far, I have not yet bought any map software. The eTrax has performed very well for that purpose without maps because when I get home I can overlay my walk on Google Maps using the Garmen BaseCamp software. My main complaints center on the lack of an on and off switch for starting and ending the hike. The device restarts the clock and all functions only when you reset the "Timers, etc." function, which is buried in the "Setup" menu. The only way to accomplish an on/off of the timer and mapping function other than that is to mark a waypoint. The joystick used to select functions works well when you are standing still, but when I am trying to maintain a fast pace it becomes hard to manipulate. I am also not thrilled with the documentation, which is contained on line or in a downloadable PDF file. As a new user of GPS I was somewhat confused by unfamiliar terminology that was not clearly defined where it was first presented. Additionally, detailed information is lacking and the e-mail response I got from Garmin to my questions was not complete. Also, Garmin's web page lists over 550 maps with only the briefest of descriptions and, again using terms and proprietary map category names that are not clearly defined. It would help allot if they showed samples of each map and something to indicate brand differences. Even after e-mailing Garmin, I am still not clear as to when I should get a map on a CDROM versus a Micro-SD card. I am looking forward to adding the California/Nevada topo maps and testing it on some hikes. Pending that my bottom line is that I am still not sure if the eTrex 20 was the best choice for me. I will write an amended evaluation after I have the opportunity to try it out on the trail.

by fromVery nice unit This unit has been very reliable and I have hooked it up to my computer to track where I've been. My only complaints: 1) software does not run on Linux, but I'm guessing most GPS units do not, 2) you can configure the top to point to either North or the direction you are travelling, but it's not obvious from the screen which you have chosen.
