Once you try the LabRadar I doubt you'll ever go back. Set up is easy right next to your shooting position, no worries about shooting it. You don't have to cross the firing line to start a new series. They work on bright sunny days. Average speed, ES, SD automatically calculated each series. The data downloads to an excel spreadsheet. If you take the plunge, get the rechargeable battery and the case. Totally worth it.
That's the main reason I went with the Labradar. It sits on the bench and don't have to cross the firing line. Very pleased so far.
