Best HR strap

[Savon]

I bought the Magene H603

I bought one from Amazon (US) a week or so back and thus far, compared to my 2-year old Wahoo Tickr, have found it to be a bit problematic in terms of reconnecting when riding indoors with Rouvy. Question is how to 'wake up' the sensor back up if you go out of range of the connected device? When I first snap the strap to the sensor, a red LED blinks on the sensor and it easily connects/pairs with the laptop, but I cannot figure out what is the process for 'waking' the sensor back up after moving out of range of the connected device - my Wahoo Tickr never has an issue with this scenario.

Oh, you are right, I totally forgot to mention that. With my Wahoo Bolt, I believe I don't have any connectivity issues, but with my Polar watch, if I put on my strap before having 'prepared' an activity on the watch (it searches for all the Bluetooth devices I have linked), I can't connect my belt. I have to take off the pod and put it back on for it to blink red. I've never had to do that with my H10.
