I really love my Soloshot3. My wife and I use the camera regularly for surfing and for horseback riding. For years, we've never had any video footage of ourselves when on the water because if conditions were good, we both wanted to be out. I considered a GoPro but what's the point? I really have little interest in seeing footage of what I saw while out there. What I really wanted was video of myself so that I could see if I looked any good and, more important, look for ways to improve. The Soloshot3 has exceeded my expectations for filming us both. I can't say enough good things about itjust amazing footage.Surfing: we each wear a tag and the camera focuses on whoever is moving fastest. Works perfectly. The range on the 65x lens is incredible. Sometimes while we are at one break, we paddle over to the next break if conditions look better. I don't know how many thousands of feet away it is, but it's far and yet we can still watch great footage. A friend of ours is a windsurfer and he's gotten fantastic footage of himself windsurfing and created professional looking videos that have been posted on several windsurfing sites.Horseback: my wife rides and we've used the Soloshot3 extensively to film her lessons. The clarity and tracking in an outdoor ring is fabulous. Much to my amazement, the camera works pretty well even when she rides in a covered outdoor ring. As you might appreciate, the covered ring interferes with the GPS signal but there is enough strength to track for decent video review if I set the zoom on ""medium"" instead of ""tight."" There is a competitive product, Pixio that works in true indoor settings but it has several drawbacks: you must charge and set up several sensors around the ring (basically creating your own GPS network) and you don't get the fantastic 65x zoom. If you are in an outdoor ring or even a covered outdoor ring, I think the Soloshot3 is the better choice.Like all new products, there is a small learning curve with the touch screen interface but I found it pretty intuitive (as a counter example, I think the UI on my Garmin GPS for cycling is fairly miserable). Make sure you check for software updates when you first receive the camera and do the downloads on a decent internet connection.Helpful hints: 1) we are very lucky that the surf break where we film is uncrowded and so we don't have to worry about theft. A friend of ours isn't as lucky but he rigged up a system where the camera is mounted and locked on the roof of his car (using the roof rack). 2) to get the fastest/best calibration, I suggest placing the tag at least 20 feet away from the camera before tapping the ""calibrate"" button. In general, the camera doesn't like having the sensor closer than about 5 feet even when filming. 3) don't forget that when you delete the video clips from your SD card on your computer, you also need to empty the trash to make the clips properly disappear from the SD card (at least on a Mac). I found this out the hard waythe SD card appears empty after you delete the clips but isn't until you empty the trash. 4) you will end up with a LOT of video footage. To manage disk space, I first scan the footage on the SD card using Quicktime and then import only the files that I want to edit. 5) if you think you might be in a windy environment when filming, be sure to get a tripod with a hook on which you can hang a weight to keep the tripod stable. This feature is pretty common on most tripods, including the one sold by Soloshot. I bought a Dolica on Amazon that I quite like.p.s. after posting my 5 star review I went back and read the 1 star reviews. My opinion is that these people didn't give the Soloshot3 a proper chance. It's new technology and it does take a few tries to get it going correctly. And yes, it takes a few minutes to turn it on and calibrate it. But the price of set up is TINY compared to the incredible results. I would strongly argue that the negative reviewers needed to make sure their software was up to date and that they took the time to read the instructions for setting the camera up. Plus follow my tip of placing the tag 20 feet AWAY from the camera during the calibration process. With a little effort on your part, the camera will serve you so, so well. It's sad to me that such a great new product is getting some harsh reviews. Compared to the alternatives (no one to film you), the Soloshot3 is fantastic.
