Never buy a new model (experimental) product in its first year he keeps repeating in his head..... The attached image is taken after running 10 times up n down the house staircase. You can see a comparison between the Forerunner 405 with chest strap and the Forerunner 235. My old trusted companion which i have had for 6 years forrunner 405 shows 143 bpm and the forerrunner 235 showing at the same time 112bpm. A whoping 30 bpm difference. Really feeling like i was sold an unfinished product Garmin
The HRM of the 235 is just unreliable and works only partially, hence useless
Garmin support got back to me in regards to my support ticket. They said they have added me to an open case, number 1187892, and the engineers have acknowledged and are working on a fix for the cadence lock.
> TomTom for example have far less users can we be so sure their optical data is perfect?
A friend of mine who is a similar standard runner has one. His HR traces are usually all over the place. For instance, we both did a race on Sunday where his HR was showing as below 100 for almost half of the race!

Does he have the 'old' cardio or the new 'spark' version? From what I understood TomTom also moved to their own sensor and that would perform less as well...
I think people having "troubles" with the hr function are expecting inappropriate function from the technology. Even cardiac pacing wires get displaced! That said, the cadence issue seems to be a problem in need of a solution.
I've only had it a couple of days but on a road ride (rubbish surface) for a few hours it performed very well done up a couple of notches (but still not tight) under a sleeve. It did struggle a little with out of the saddle efforts but I've got very skinny wrists and I think it was lifting slightly. On a steady state tempo run into work this morning it was certainly up to the job. Slackened off when sedentary it still reads fine.
People seem to forget that chest straps have their issues. I find them a bit annoying at times and there appears to be none of the outside interference that sometimes occurs even with coded chest straps. If you want accurate hr during hard intervals (not sure why you would) then you can always wear a strap.
I was wary about purchasing one based on the issues described in this thread and other sites but I'm certainly very pleased with the performance. I'm not convinced that I will ever use a chest strap again.

I agree that people seem to have very high expectations for a non-medical device. Cadence lock aside (which I've never experienced), the general function of the optical HRM is working very well for me. It tracks with exactly what I expected. Last night, I had another treadmill run but my speed was very slightly increased. The run also felt a lot harder, likely due to exhaustion on my part. It felt hard from the very beginning. And, as expected, my HR was a bit higher than other similar runs that didn't feel as hard. The average was a few bpm higher as was the max HR. It's exactly what I would've expected. I also have had no issue with it recognizing intervals. I'm not sure how short some people's intervals are, but I take 1 minute walk breaks in between running segments. My HR always comes down very quickly within that 1 minute window and then goes back up as expected once I start running again.
I went a on an easy 9 mile run last night. Average pace 7:29 a mile. I would have expected my heart rate to be between 125-135 bpm. Unfortunately, my average heard rate for the run was 170 bpm, and with a max of 192bpm. Cadence was 181 with max 193. Something is wrong. I did a workout a couple days before and I ran a 5:48 mile and my heart rate didn't exceed 161 bpm.
Yeah, seems something amiss with your unit or how you're wearing or something. Not the sort of results I'm seeing.
Today I did a 4 mile run with both my 235 and my 920xt + HRM-RUN. I'd done a handful when I first got the 235 in December and was satisfied enough with the results I quit wearing the 920xt. In trying to debug my SDM4 footpod not auto-calibrating on my 235 I've taken the 920xt out a couple times, and today also remembered my chest strap.
Oddly the 235 was reading high just before the run, not sure why, but it normalized within the first minute. Threw off the average HR a tad, the two watches were 2bpm different (149 vs 151). Looking at the splits, average HR was 1bpm lower on the 920xt than the 235. During the run anytime I glanced at the watches the displayed %HRR was within a point of one another (excepting that brief anomoly at the very beginning)
For an accuracy of being within 1%HRR, I'm more than happy to skip the wet and cold chest strap.
Headed out this afternoon at easy pace and instantly got a really high heart rate reading (around 165 I think) which just kept rising - in line with my cadence. I stopped and started and the HR didn't budge. It was weird. I had tightened the watch a bit more than normal so I loosened it a notch. The I really upped the cadence and dropped the pace and the HR immediately dropped to 133 or so. Sorry I can't post a link yet - posting from phone. This was my first run since installing the 2.41 beta firmware.
I'm thinking that I was wearing the watch to tightly and for some reason this caused the cadence lock. I've never seen it lock onto the cadence immediately like that.
