How accurate is this device?

I'm afraid that I, too, fall into the group of those who can't give a good answer to this rather simple question. My reason is that I returned it very soon after I got it because it failed my KISS test ("Keep It Simple, Stupid"). In other words the WCI unit did so many other things, above and beyond the basic cyclometer functions that were all I wanted, that I found it just too, too complex and have been "doing without" ever since...

Better than the cell phone app and the nike watch I tested and compared it to so far. Still do not know if it is sensitive enough for sailboat racing. Still racing each Sunday but had other problems to solve first..

Not very. I took it on my running route and while it always gave the same distance, it was about 10-15% short every time. The route wasn't tree covered or among large buildings either. I guess if you know the error margin you can still work with it, and it might still be worth the price.

This unit is pretty innacurate. It will give different readings (upto 30mb) if you don't position it exactly the same way each time, and will also give inconsistent readings (upto 15mb) if you takes consecutive readings without adjusting it at all.

I didn't have any problem. However I sent mine back due to I didn't/don't think it gave me accurate readings.

I have found it to be extremely accurate especially after it's fully locked on and using WAAS. It's receiver is sensitive enough to reliably navigate from the window seat of a passenger aircraft and from the forest floor in tropical rainforest. How accurate depends on how long you leave it on to acquire satellites and whether or not you are in a WAAS area? There is an accuracy estimate on the satellite screen.

Agree with the comment about doing things just right. Mine is very accurate. I will say I messed around with it a bit in the beginning to see what would make it go astray. Generally speaking though it is very accurate. I have had no problems.

I have this meter and I do use it every day. As a matter of fact I have three. I love that it takes a wheel and the wheel has ten test strips on it. However, I can't vouch for its accuracy. I have taken my blood one right after the other with two different meters and they are as much as 20 points different. I still use it though.

Yes, I had no problem with it being accurate. I do a lot of country road running and I have tracked it in my car the miles are the same. :)

I really can't tell you. I am not sure myself. I use it for a rapid heartbeat. I do believe it is somewhat accurate. I plan on testing it out the next time I visit my doctor.

Just got mine a year ago. It is very accurate within it's stated variables. I have two friends with iphones- they are all over the area while my eTrex 20 usually takes me very close, if not right to, the cache. Two thumbs up!!

It seems to calibrate itself upon startup. It will calibrate itself to zero if you turn it on with a container that you intend to fill already on it. As for it's need to be calibrated for accuracy, we'll we just have to trust to the gods of electronics. That said, I've never felt it might be even slightly beyond negligible where error is concerned. I'll buy another if mine ever poops out!

Yes it always updates speed readings quickly even at WOT but I haven't checked it against another gps for accuracy.

Seems to be pretty accurate.It will depend a lot on the preferances you enter on your gps.

Hi,Very accurate. It's the best one I have owned. Love the light in the device because it illuminates the numbers

Mine seems fairly accurate yet sometimes takes 4 or 5 tries before giving me a reading. Also, very occasionally I get a "high" reading (like 156) that I know is wrong. So I just wait a minute and re-check. This happens very on very seldom occasions.

It is accurate. If you do not listen to very high levels, it works great. It drives my 4 Dynaudio very well and they are demanding. When the charge is too much, the Wadia switches off automaticaly and you just have to switch it back on. For more info, write to me sergebarbeau@yahoo.com.Hope this helps.

Yes, we use in aviation and its very accurate! I saw some app to walk and you can conect this device. Good luck.

I have not, but I think you may be disappointed with your results. My experiences continues to be that this devices is most accurate and reliable when your forearm is held in a position that keeps it parallel to the ground as when you are running or fast walking. When the forearm is held in another position its performance is highly suspect. I was sent a firmware upgrade in May of this year that helped a little but it still isn't ready for prime time in my opinion.
