Polar Loop Activity Tracker Heart Rate Monitor

Polar alignment was simple and tracker worked past 2 and half minutes when shooting.

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.

Bought this polar meter to use with my recent purchase of the vixen polarie star tracker.... so easy to align with the north star, buy one of these if you want easy alignment with polarie star... mind you later on I will purchase the polar scope...

The polar tracker came with everything as described, and included another weight that wasn't described in the details, the weight was as handy as many reviews claim, it is needed in some cases, I agree. The instructions have a sticker with the correction. It just works and for me, without a clear view of Polaris, the 3 star alignment works just perfect. It would be nice if B&H include the V-style dovetail for DSLR/Mirrorless users, the Shutter Release Cable, and the 12V 2A (2.1mm plug) Power Supply in the Accessories area for this item and a link to the Sky-Watcher walkthrough of the SynScan app which make it work just perfectly. 5 stars, great polar tracker.

I had another brand of star tracker that my toddler got her hands on so this was its replacement. The polar alignment camera with this setup is amazing. All my subs are spot on from one to another which I had difficulty attaining with the alignment scope my other tracker had for polar alignment. I'm using a DSLR and a 135mm lens. Pros: Small size for easy transport. Polar camera makes polar alignment very accurate and easy. Tracks like you would expect it to. Built in chargeable battery. Cons: No way to control camera shutter without an additional hand controller which is sold separately. You'll need an intervalometer if your camera can't do multiple long exposures by itself.

I have been using the Star Adventurer tripod, with my Star Adventurer tracker. But when it came time to do my polar alignment: turning the latitude base, towards Polaris, the latch (on their tripod) made it difficult to do that. I struggled with it. But with this tripod, the knob makes it so much easier to turn the whole base towards Polaris. It's big enough to grasp and turn the tracker towards Polaris and lock it in. This made it a time saver for me out in the field.

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

I decided to try an upgrade from an 8BG RAM to a 16GB RAM because of two issues. One, my activity monitor, at times, indicated a small degree of Memory Pressure, and two, I thought one of my main programs probably needed more RAM. Very happy so far. My Activity Monitor now seems to indicate 10 to 12GB of memory used, so I assume my additional 8GB of RAM is helping. Not sure I can actually tell the difference going from 8 to 16GB of RAM but the additional RAM appears at least to be useful according to the Activity Monitor.

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