I have a MEVO and SC300. For the past few months I have used them for short game practice, 40-70 yards.
What I have found, for normal, high shots, they are similar, within a yard or two, and pretty accurate.
If I hit a lower, groove low, hop and stop type of shot, the SC300 is accurate and the MEVO measured long by 5-10 yards.
I had a friend spot the landing of a lot of shot shots between 40-70 yards and using a rangefinder, compared the carry distance to those displayed on each device. Happy with both but would not recommend and MEVO for shot game measurements.
