The difference that matters
The Ernest Sports ESB1 measures spin directly, while the Shot Scope LM1 does not report it. Only the Shot Scope LM1 is listed for outdoor use as well as indoors. At the prices we observed, the Shot Scope LM1 costs $75 less.

Highlighted rows differ. Figures come from each product's sources; room depth, distances and brightness are FOREference calculations using the same method for both.
Which should you choose?
Shot Scope LM1
Choose the Shot Scope LM1 if you also want to use it at the range or price leads the decision ($75 less).
Before you buy either
- Check the room: room size calculator and ceiling height calculator.
