5 Stars love it
I have been so happy with this addition to my Garmin. I also got the bike mount and it works great! It was all so easy to attach to my bike and start working with it right away.
5 Stars Garmin GSC 10 Speed Cadence sensor
I am using this on my second bike - and it and the entire Garmin Edge 305 system, works very well.
The Edge 305 has multiple bike profiles, so I’ve tuned the second profile to this sensor.
Care needs to be taken to install the sensor correctly so it aligns properly with both speed and cadence magnets.
The only observation is that the cadence magnet, the one that sticks on the left crank, is a little tricky to space relative to the sensor. In one bike it required a home-made spacer, such that it would bring it closer (within spec) to the sensor. This will depend on your bike and as I said I only had to build this for one of my bikes. Still, it would be nice if Garmin offered such a spacer.
3 Stars Re-scan always necessary
This Cadence sensor is for my second bike.
The manual says the Garmin Edge 305 automatically scans for a cadence sensor every time the unit is powered up. They are serialized somehow to avoid picking up somebodies else’s data. When I move my Garmin Edge 305 from one bike to the other, I must always plow through the menu system, usually while trying to start my ride, to make the 305 re-scan for the new cadence sensor. I suppose it looks for the last cadence sensor it used, which it can’t find so it gives up until I have to tell it look for a new sensor. This is a nuisance but otherwise it works fine.
5 Stars Garmin GSC Sensor review
The sensor is a great addition to the Forerunner 305. I was able to switch out my catseye computer and use this instead. It is very accurate and was very easy to install and set up. I like that it has cadence and a wheel sensor as I will use the bike in the basement during bad weather on my fluid trainer and it will still give me distance. I would suggest it to anyone that is going to bike and run with the Forerunner.
1 Star Flimsy and cheap
Despite mounting all the pieces exactly as instructed, I couldn’t get this device to consistently work. The plastic slides out of place at the slightest bump, and within 2 weeks the sensor arm has come loose and snapped off. I’ve got a Garmin Forerunner 305 and absolutely love it, but would not recommend this accessory.
