Things I liked: It's very easy to use and the instructions are straight forward and understandable. Also having the ability to record so many strings without stopping is great.

Things I would have changed: Nothing at this time.

What others should know: This was my first Chronograph and after reading reviews about how easy it is to use right out of the box compared to the other brands, buying this was a no brainer. I enjoy using it every time, it's not a chore.

Things I liked: Quick and Easy to setup. Good range of detection. Good shot tracking and calculations. Multiple shot strings.

Things I would have changed: Its a little light weight. I think I would add a piece of bar stock inside the base to give it a little more grounded feel when sitting on the table.

What others should know: I had that "other brand" of chronograph before, and after getting my Pro Chrono Digital I will never own one of those "other brands" again. The difference in ease of use AND quality of use is an order of magnitude.
