Are Polar Heart Rate Monitors Accurate

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.

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.

I found the SkyGuider Pro to be a sturdy-built apparatus. It makes polar alignment fun and accurate. It comes with all the features necessary to get great 2-3 minute exposures with DSLR. It also has an ST-4 port when I am ready to expand to a small telescope and autoguiding. I ordered the optional ball-head mount, which allows me to point my camera in any direction. The SkyGuider Pro has very accurate tracking. This is an excellent investment and a great addition to my astrophotography options.

I recently purchased the SkyGuider Pro and had occasion to use it a few nights ago. I was able to do an accurate polar alignment and was rewarded with 4 minute exposures with pinpoint sharp stars! I had a Nikon D850 with the 14-24mm wide angle. The camera, lens and ball head weight over 5 pounds. I actually need a second counter weight to get a good balance. Even with it being slightly out of balance, it performed perfectly. The only downside is the base. If you are shooting north of 36 degrees, you will want to get the Sky-Watcher Star Adventurer Equatorial Wedge Base, $65 on B&H. It will go all the way to 90 degrees and is much easier to use.

Works as advertised. Polar aligning is fast, easy, and accurate. I'm able to find stuff a lot easier now. I highly recommend this.

Great tracker for medium set up. Polar alignment is very simple and tracker is very accurate without a rracking scope.

I can fit 2 of my BenQ 27 monitors & cables perfectly into this sweet heart!! I absolutely love it it has made my life so simple!

Bought 2, so far the monitors are great. Clear, 240hz refresh rate is awesome.

Superb studio monitors, with amazingly robust, but very tight and accurate bass.
