Heart Rate Monitor With Optical Sensor

This watch has some many useful function including calling for help if you fall, heart rate monitor and other health app. I feel like Dick Tracy when I speak into my watch using the intercom or answering a phone call.

Great that he can monitor his heart for afib and take an EKG whenever he wants.

This is the third Apple watch I've owned. It seems that this watch works a little faster than the others. I use it as much for health issues. The Heart Rate monitor picks up the same as my belt. This is an improvement over the past watches. The Blood O2 is good, particularly now with Covid as lung function is an indication of the virus. All in all it's a worthwhile purchase.

This watch is absolutely perfect for my husband and I. We aren't sports fanatics but need to keep track of heart rate. We walk, ride bicycle, and treadmill. This watch tracks it all. Best of all, we only have to charge once every 3-4 weeks. Just wish I could get another one in the white rock color.

Purchased as a gift for my wife. I felt she required the heart function and pO2 sensor capabilities, but she was reluctant to switch from her simple $35 Timex model she needed to purchase every 2 years (it’s lifespan). Well, still learning to use functions and appreciate all the capabilities, but SHE LOVES IT!

I love this monitor. It was easy to set up and the instructions were prefect. I'd buy another one in a heart beat!

i use this as a second monitor and couldnt be happier. tHIS MONITOR PERFORMS JUST AS YOU WOULD EXPECT IT TO. THE REFRESH RATE IS INSANCE AS WELL. VERY GOOD PRICE

Amazing monitor! Refresh rate and clarity is incredible

The speedbooster ultra fits snugly onto the GH5S; with zero play: perhaps it’s the oversized sensor. The optical clarity is superb. The bokeh it produces when paired with the sigma 18-35mm 1.8 is a beauty. Does not vignette. No chromatic aberration. Works right out of the box without any necessary adjustments. Overall, I’m very pleased with the purchase.

Works great, the optical slave mode works even when the sensor is not in direct line of sight of the flash. Very happy with this purchase. Is so bright, i rarely increase it above the lowest setting.
