Temperature data screen - swim activity not working after 7.8 update

I am very disappointed! Measuring temperature was the key aspect why I purchased the Garmin Forerunner 945 couple weeks ago to track cold water swimming. I want money or the feature back.

Internal sensor did give extra degrees to the water temperature when the water is cold. Maybe it's not so big in tropical waters that are more close to your own temperature, but water that is like 13 degrees in celsius your own temperature did cause it to be too much.

And for the reason. Saving battery. I think was it Suunto or Polar does the same, disable baro during swims as it's not giving proper data and the temperature sensor is for baro.

I was about to buy Polar but because of temperature I choose Garmin :( There should be an option to turn it on or off according to the user.

Return it then.  The temperature readings while in water weren't that accurate anyway.

It was never a feature.  You won't be able to find any literature from Garmin where they say their devices were designed for (or even capable of) measuring water temperature while swimming using the internal thermometer sensor.  The purpose of the sensor is to be used with the barometer. 

Is tempe waterproof? I did not find in the specification.

The manual says water resistant to 10M (32.9 ft). 

You need to attach the Tempe then very close to watch to maintain connection in the water?

Yes. I clip the Tempe to watch strap on the top side of the watch. Put the strap though the Tempe clip and then push Tempe to the clip. I think it's works pretty nicely like that.

jmto, thanks for answering. I will try that. Unfortunately my OWS season is done for this year. I was quite happy with the internal Temperature sensor. In swim workouts longer than 30 minutes my unit was quite accurate. Anyway water temperature was not why i bought the FR945
