Here’s a great new product! This Chronograph does not have a tiny space to shoot through, helping prevent getting shot to pieces. You simply shoot over the chronograph parralael to it. It has an indoor and outdoor mode and can be changed from FPS or MPS. The app works great even on newer android phones and allows you to see and copy your shot string, change modes on the chronograph, change the interval time between shots and set the weight of your pellets to calculate energy. IPhone app has been made but is still in testing stage. You can use the chronograph without the app, but it isn’t near as user friendly without the app. If you are an iPhone user you can add on a used alcatel tablet or lg phone to use. Will come with app installed.
Takes one 18650 rechargeable battery. Batte ry and charger included.
