Polar Target Heart Rate Monitor Manual

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.

Perhaps not my most capable mount, but definitely my favorite. Setting up and polar aligning is super easy and quick. On my first night of use less than 5 minutes had elapsed between bringing the tripod outside and when I began to image. For those who are used to imaging with motorized mounts (in both RA and Dec), be aware that using a ballhead to find your target can be a bit challenging, especially when trying to image targets in a relatively empty part of the sky at, what for this mount, would be considered longer focal lengths (100mm or so). Definitely recommend using a geared ballhead and/or laserpointer attachment to help make target acquisition easier. Otherwise, I expect that this mount will get the most use out of the three I own.

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

Love a product that is inexpensive, works fine, has no owners manual, and fits its target device perfectly. All life should work this easily.

Easy to mount, well made, manual online, easy to zero on target. Reticle is clear/useful. Consistently hit bullseye at 100 yard target.

I've always felt that the focusing on my 600mm Nikkor was just a tick or two off. After reading many reviews and researching all of the alternatives, I finally decided to purchase FoCal 2.0 Pro along with the large hard target that is needed to calibrate telephoto lenses. Everything arrived promptly from B&H. The software came with only a quick start guide, so I went to the Reikan website and downloaded what turned out to be a 177 page manual. I started to read the manual and quickly became very intimidated. While I am somewhat of a technology nerd, this manual was going into detail over software features that made everything sound very complicated. It wasn't until I got to chapters 10 and 11 that they finally pointed out that the software can handle everything automatically with just a few clicks of the mouse. That's what I wanted! Setting up the target was quick and easy. The best part is that the software told you whether or not you had the target set up properly, and told you specifically what factors were incorrect. Given the fact that I was calibrating a 600mm lens with teleconverters, the target had to be set up a good distance from the lens. I also had to make sure that there was sufficient light shining on the target. With one click, the software told me what parameters I needed to adjust and once I made the adjustments, it confirmed that everything was good. From there, it took only a few minutes to calibrate the lens. Unfortunately, on a Nikon D800 the software will not automatically make the micro focus adjustments. However, it does audibly tell you what settings to make during the calibration process, which were simple to make through the D800 menu. After just a few minutes, the calibration process was done, and FoCal confirmed my suspicion that the lens was back-focusing just slightly. I quickly ran out to a local conservation area and took a few bird shots. I truly believe that the calibration improved the focus accuracy.

This product is as easy as one, two, three. Set your camera to manual, shoot the target, set white balance. Excellent tool for digital photography.
