Extreme Weight Loss Fitness Tracker

Although the most expensive of the fitness tracker watches, it worth it for serious trackers. Highly recommend.

I use this on my star tracker to allow panos. It is light weight and very secure. I have used other that are now in the trash. This one is a keeper!

I love this. It is barely any extra weight and gives me the peace knowing that I have a tracker on my camera!

This ballhead is a great option for tracked astro. My star tracker with no counter weight desires a ball head attached strait to the tracker itself... at 26 degrees (low latitude). This macro ballhead allows me to operate at a much better angle then a traditional ball head (even one with a vertical notch) making this substantially more versatile then a traditional ball head for this use case. Amazing construction, light weight, rock solid hold, and great family owned company!!..... Pretty sure this is the last ball head I'll be buying... ever.

The tracker works without any weights only with a light load, like a Sony A7x class camera, a VERY light and compact ball head, and a light (and slow) lens, like a Loxia 21mm f/2.8. The total weight must be less than 3.3 lbs, or you will end up ruining the tracker. If you use a more normal ball head and a lens like the Venus Optics Laowa 15mm f/2, you will need one of these counterweights. If you use a heavier lens like a Sigma 14mm f/1.8, then one weight is not enough – you will need two. Also, for a Sigma 14/1.8, I would also recommend a support bracket to minimize vibrations, and that would add its own weight. So you will need two counterweights. And lastly, if you want to shoot the Andromeda galaxy with your 600mm f/4, you will probably need three, maybe even four of the counterweights. So buy as many as you need, depending on your use case. The counterweight itself is made well - it's as compact as it can be, without going to heavy metals like lead. It has a nice finish and easy to handle. The screw knob works well. And yes, you can use it to crack walnuts and it hurts if you drop it on your toe.

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.

This is a good tracker for carrying to offroad sites. It has a decent payload of 6 pounds, but they say use a x counter weight if above 2.6 pounds, which is just about every camera and lens. The built in polar scope is much easier to use than its big brother the Skyguider. Price is right for a strong tracker.

I use this cart daily. You need a 5-6' long area to keep it.. Holds extreme amounts of weight. Rolls very easy. Use on NYUC Sidewalks, NJ grassy fields, and doesn't quit. I love love love this purchase. Best Cart I've ever bought.

This teleconverter is very solidly build. It is a hunk of glass and the weight is quite substantial. I have never owned a teleconverter before, but I wanted the extra reach. I use this with the 100-200 and there is no loss of image quality. If there is, it is so minimal it is not noticeable. There is a loss of 1 stop of light; f5.6 is now f8.0. Metering reading, autofocus, and all communication with the camera is there. I'm pleased.

Very compact, light weight binocular. I had the 10x50 Nikon Action Extreme already and love it. The 7x35 is just as good. Quality optics, great collimation, nice eye relief. Excellent binos for the price.
