HRM

I actually have 3 - in order of awesomeness

1. Timex Run Trainer GPS with HRM Soft Strap (for use when in the gym, walking, running, and anything non-bike) Newest
2. Garmin Edge 500 GPS with HRM Hard Strap (for use while cycling both mountain and road) Newer
3. Bowflex Precision XT (don't really use anymore, bought for cheap off some random website a couple years ago) Old

The TRT is probably the most versatile because it has GPS and heart rate. I use it for things when I'm not on the bike. I use it in the gym, and it allows me to turn off the GPS so I can just get heart rate. It has an optional foot pod for running inside that is good for tracking cadence and also pace (it over rides the GPS if running outside). You can toggle on/off whichever feature that you want (HRM, Footpod, or GPS) which makes it very valuable to me. The TRT uses a specialized version of Training Peaks which is a bit overwhelming at first, but offers a ton of features.

The Garmin Edge 500 is a cycling specific computer HRM and GPS that doesn't really fit my non cycling activities because of the size of it. All in all it does a great job tracking though. I could probably sell it now that I have the TRT, I do like the Garmin connect website for tracking my training. It is simple and straight forward which I like.

The Bowflex is my oldest HRM toy and my wife seems to have a liking to it now. She wanted something similar to the TRT and she found that even though it doesn't have GPS, it fits her needs fairly well.

Out of all of the straps, I do like the soft strapped HRMs the best out of the 3 straps. It seems to be the most accurate, slips the least, and is the most comfortable to me.

Hope this helps!

With the TRT are you able to input your age/sex/weight ?
