Cadence Sensors

What are other cadence sensors that work with Garmin 520?
That will not break the bank?
I have an older Garmin sensor that is the larger model from a few year ago. The cadence display keeps going out all the time, and i get a red light always,
looking to get one of those more simpler newer ones? anything else lower priced then Garmin?

I think you'll find that any of the quality sensors (Garmin/Wahoo/Polar) are going to be in the same price range, There are much cheaper sensors but you'll need to expect that they may not last very long or work as well. You may save a buck or two by doing some internet shopping to find the best price.

For what it's worth here's a minor nitpick: the Garmin cadence sensor is designed to be held on with rubber bands, with the battery hatch facing the inside crankarm. If you don't like or trust those rubber bands, you can tape it on the normal orientation such that you have to peel off and replace the tape when replacing the battery. Or you can tape it on the opposite orientation, in which case the hatch is accessible but you can't see the status LED. Or you can use a ziptie which blocks the hatch in both orientations, and must be cut and replaced each time.

I got one Garmin in a package with a computer (I guess mine is the version 1). I got the Wahoo for a second bike. It has no hatch, the two halves snap together with a little screwdriver slot to pop it open. It can be taped on with the LEDs visible, or there's a little rubber boot+strap to hold it. Ziptie won't hold it securely, and would have to be cut to service. When taped on, it's a little cleaner looking than the Garmin with its protruding arms/hooks.

Battery lifespan is looooooong, so this is really splitting hairs. Both work fine for me (no connection problem like you describe), though I just like the aesthetics of the Wahoo a little more. The main annoyance (with both) I have is if I start a ride from the computer 3+ minutes before moving the cranks, the cadence sensor will go back to sleep. Then I have to notice the "---" where cadence should be, stop, pause and sleep the computer, wake it up to restart the sensor search, then ride off. Not a big deal

PS - ah, I just saw your other thread with pics. Why two threads at the same time? Regardless you're talking about problems with your combination spd/cad sensor. My comments are about the separate self-contained cadence sensors that live hidden on the inside of the left crankarm (like in the link in post #2 ). I got sick of the combo sensors getting kicked and bumped out of alignment too often. After I switched to separate spd and cad sensors, I pretty much forgot they were there, they just work.

I’ve been using CooSpoo dual Ant+/BT sensor (and HRM) the past year and never had a problem. Half the price and works the same.

I needed a dual HRM for indoor cycling and wanted to try the speed/cadence sensor at the same time. They both work reliably, and battery life seems to be going strong for now.

I've been using the Magene S3+ Speed and Cadence Sensor with my Garmin Edge 820 for almost two years with no issues. $17.45 on Amazon.
