I won't be trading my LabRadar in any time soon. I love it! It's never missed a 17 caliber bullet from my CZ527 in 17 Hornet which may be due to it being more precisely aimed with a red dot sight mounted on top. Although it's a pain, you can add data from different times together with the Excel spreadsheet data summary. Currently I'm keeping my 22-250 and Swift below 4,000fps, so the velocity limitation hasn't been a problem.
