    Comments about PowerCal Bluetooth Smart:

    The best value for power training. Accurate enough to get power feedback (within +/-5% accuracy for 20 and 60 minute threshold tests) and the easiest system by far to swap between bikes. Have been using 4+ years and still going strong. Used with Edge 500 and 510 (Have ANT+) without a problem. System even tells me when battery is running low and you simply swap the CR2032 coin cell battery out. Have only replaced battery twice in 4 years after 15k+ miles.

      Very simple to use product for not much more money than a standard heart rate strap.
      The data is not as accurate as a full priced power meter but at this price you wouldnt expect that.

        Comments about PowerCal Bluetooth Smart:

        This is my second one -- I bought it just to have a backup, though my first one has been flawless going on a couple years. It's a great product. No it's not a full-blown power meter but it's not meant to be. It's also only a FRACTION of the cost of one. It gives you a rough estimation of your overall power, and great to give you an idea what your NP, IF and TSS are. You can compare from one ride to the next. If you're a road racer and using power for training then you'll need a true power meter but as a mountain biker just looking for a ballpark range then this product is perfect.

          How can you build a blue product, that doesn't work with your own computer. Is worthless. Doesn't work with any other third party app, with the exception of strava. I can't figure out why. The reason I wanted is to record the workout and track HRV, using a third party app.

            Q:

            Thanks to Paul for helping me identify that the way to Sync to my iPhone was to do so through the PT app. Sync'd straight away and reporting good data. However I have been unsuccessful at syncing with my cycle computer (Magellan Cyclo Mia 505), speed/cadence sensors & heart rate sensors not discover-able. This means I can't get a visual on the data while i ride (without pulling out my phone) which makes it pretty pointless. I can't find anywhere a list of cycle computers that it is compatible with. Does such a list exist? Can anyone point me in that direction? Why make external sensors that are not compatible with most devices that will display this data....doesn't make sense to me.

              Unfortunately the Magellan is not compatible with your sensors. You will need a Bluetooth 4.0 Smart compatible head unit and here is DC Rainmaker's list: https://www.dcrainmaker.com/product-comparison-calculator

              Otherwise the Wahoo Elemnt is compatible

            Q:

            Hi, very excited when my PowerCal arrived. Brand new straight out of the box, BLE version - tried pairing with an iPhone 7 & then Magellan 505. It wasn't discoverable on either device. I swapped out the battery for a brand new one. Still neither device would pick it up. I wet the electrotes and jumped around a bit to try get the heart rate going. Still not discoverable. Is there anything else I can try before returning it?

              I have the powercal and speed/ cadence sensor. I had issues too with the battery being flat when arrived. Replaced battery and it worked with iphone. I now have iphone 7 now and don't recall syncing sensors. I think I just downloaded the powertap app and switched on Bluetooth and it worked. It's a great package once you get it going. I stopped using garmin and just use phone on the bars. I get full data with the app. Also syncs with Strava.
              Good luck

              It looks like the Concept 2 rowing line doesn't accept a Bluetooth signal. The PowerCal BLE will not work with their proprietary software.

            My wife uses the Ant+ version of the strap (bought just over a year ago) successfully with a 310XT.
            I've given her a new 920XT for Christmas. It is picking up the strap as a power sensor but doesn't seem to be seeing it as a HRM.
            Any suggestions

              You'll need to pair it separately. Once for HR and another time for Power.
