Polar Heart Rate Monitor Original

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.

The PolarPro Base plate is great to have and at an affordable price. I have used the original screw on Polar Pros and it was just to time consuming to have to unscrew them and put them on another lens or having to buy multiple ND's I now have these magnetic plates on all my lenses and this has been a life saver because I just leave then on all the time.

I have two of the original StarSense Autoalign devices. When I saw that Celestron had come out with a new version that included autoguiding, I bought one immediately. I have so far never mastered polar alignment and mostly concentrated on very short exposure photos of the Sun, Moon, and planets. I did not look forward to having to learn polar alignment and buying a guiding camera and installing guiding software and getting it all working. The StarSense Autoguider solved all these problems. It was simple to install (just replaced the original StarSense device) and simple to calibrate. I have a very restricted view so I set up 4 points that described my available view. Now I just click and the StarSense Autoguider does the alignment. I then point to the object of interest and click on guiding. (Note, I didn't do a polar alignment.) The guiding works - once selected it points to the object for hours if need be. Celestron says to get the best results you should do a polar alignment, but it works so well without it. The alignment and set up for guiding literally takes just several minutes. I didn't have to install any new software as Celestron's free CPWI software handles alignment and guiding seamlessly (along with with focusing, dew heater control, etc.). The photo shows the guiding accuracy which is almost always within about +/- 1 arc second. You can use Live VIew to see what the guiding camera sees. You don't choose a star - StarSense uses all the stars it can see for guiding. It works with stars, nebulae, galaxies, planets and the Moon. I highly recommend this product. It's quite remarkable.

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

I love this camera with all my heart.
