If you shoot at a range where they have cease fires, a remote display is almost a must. I have a Beta Master and it works fine.
Recommendations:
Replace the metal skyscreen sticks with wooden ones. I made "ghetto" ones with Panda Express chopsticks glued together. That way when you shoot these, the wood takes the blow and the skyscreen inserts don't break the sensor body.
After you set up, shoot some rimfire/BB/Airsoft/pellet rounds through it to make sure the conditions are good for chronographing. No need to waste good rounds just to find out the setup is not good due to sun setting behind your back, etc.
Take your manual with you. The Shooting Chrony's do a good job, but the interface and control is so 1970's. It tries to do everything with just 2 buttons.
The Beta model has 6 ten shot strings and performs statistics on each string (max,min,average,extreme spread and standard deviation). I write all my readings in a notebook and transfer them to an excel spreadsheet which is set up to do the same thing so the multiple strings is not necessary nor is the statistics, but it might be handy to others. I probably would have been happy with the Alpha Master, but the Beta was the same price when I bought it so no loss there.
