4.0 étoiles sur 5 watch was OK on the second try 2 août 2012
Par D. Thompson - Publié sur Amazon.com

I recently purchased one of these from Red's Gear through Amazon. It replaces a similar unit made by Suunto. Before that, I had separate altimeter watches and heart rate monitors, used for hiking and biking. The previous reviewers (where did those reviews go?) either loved the device or found it useless based on the altimeter logging function. There were two problems, in addition to the incomprehensible sequence of actions that you need to remember in order to make it do what you want. (What kind of mental processes do these guys have?)

To begin with, the hardware is first rate, and a bargain at the price. But the software was designed by some junior engineer who had never been outside an exercise gymn. After all, what does a hiker want? Current altitude during the hike, max altitude, min altitude, total ascent and if it's not a loop hike, total descent. So what does this watch save in the log? Ascent, descent, avg heart rate (who cares about the average?) and some bogus calorie number. No max or min altitude. Moreover, and the reason why some reviewers hated the watch, the ascent and descent numbers were completely off the wall. 50% too high in some cases, and it would log hundreds of feet when tested at my bedside overnight.

The reason for this was due to that same junior engineer. Other altimeter watches will not register a reversal from up to down, or vice versa, of less than a hundred feet or so. This watch seemed to register every change in direction, even those of a few feet. The display will show a one foot change in elevation. The A/D converter might have that much resolution, but it can't have that kind of accuracy. There has to be some digital jitter in the measurement that would look like small reversals of ascent/descent. It appears that they programmed in about a 15 foot dead zone to take care of this problem. But unfortunatley the digital converter for barometric pressure had a stutter of 25 feet or so, which occurred multiple times between 600 and 700 feet elevation, and again between 1200 and 1300. So a walk straight up the hill behind my house, a net 1100 foot climb, was showing up as a 1600 feet total ascent. This even though the altitude at any moment looked pretty close to right. It was horribly wrong, and Red's Gear won't take it back. So off to the mfg warranty center it went, and back it (probably a new one)came. This one has no glitches in the converter, and I can find no error with it. It does seem to have that 15 foot dead zone between up and down, which is fine, and which is much less than any other cheap watch I can find. I haven't been able to catch it any errors. It's calibration seems fine, being within 50 feet per topo map or gps on any day if it has been set properly at the start of the hike or bike ride. I did an eleven hour hike in Yosemite with a lot of ups and downs, total up of about 4500 feet, and it compares perfectly with the gps track projected onto a topo map (Delorme software)i.e. about 10% less than the number Delorme gives because the total up from the map software is usually at least 10% high due to their errors in contour line interpolation.

In my experience, an altimeter watch will slightly underestimate the total feet of climbing, and Delorme will always somewhat overestimate it. Of course, if your route were completely monotonic, with no little dips, the altimeter ascent number should be completely accurate. But that never happens...

In other words, it works fine. As well as any aneroid altimeter that I have owned. and it is cheap. But the designer was too optimistic on the size of the dead zone, so you need make sure that you get one with an almost perfect barometric digital converter.

Now, if only it recorded max and min altitudes....

4.0 étoiles sur 5 worth the money 27 août 2013

This watch is not extremely accurate with regard to elevation and barometer as far as I've tested, but none of the sports watches within a reasonable price are. That said, it is accurate enough to be functional. The band is really comfortable and the watch is not excessively large like many of the others. It is also lightweight. The functions were easy to figure out and use. My biggest complaint is the mode constantly changes because the buttons hit my arm or wrist while i perform normal daily activities. I find myself pushing through all of the modes to get back to the time mode every time i want to check the time, which is somewhat frustrating.

Does it all!

Chronograph, HRM, altimeter (total ascent/descent), alarm, light, two time zones, total calories.

Plus you can change the battery yourself - without sending it out to a service department (which is one of the reasons why I decided against a POLAR product).

I had an older version of this product and loved it just as much.

I use it for mountain trail running. I especially like the fact that the altimeter has a chronograph so I can track my total ascent/descent as well as total time for my run.

5 stars!

This is my second highgear in ten years and I swear by it! Way more afforable and way more durable than my Suunto was. The wrist watch HR monitor interfaces with my polar soft strap which is nice. A great reliable piece of outdoor gear!
