I got my velociradar about two weeks ago and have had it at the range 8 or 9 times now. At 100 yards, it works great. However, if you want to capture the same information on a target beyond 100 yards it gets a bit tougher. The radar beam appears to be very narrow and the unit is very sensitive to aim. The on-board peep sight works fine at 100 yards but not beyond. I brought this up to the people at Caldwell and was told that the unit was only designed to work at 100 yards. In order to make the unit work on longer shots, I had to place a paper target at 100 yards, close to the flight path to my 500-yard target and aim the radar at that 100-yard target.
The included tripod is too flexible to be useful if its windy. I place my unit on a good camera tripod slightly above the height of the barrel and aim the radar down slightly. This seems to cause the bullet to pass through the beam and results in better consistency. Battery life is good on the unit, I usually get three or four trips to the range on a charge. That probably equates to 6 or 7 hours use.
The Phone interface is good and allows you to do most functions without ever touching the unit. I did find that after a period of not firing, to allow barrel cool-down, it was best to activate the Radar Pause button once to ensure that the unit was ready to capture the next shot.
Overall, I like it. This was an upgrade from a Magneto Speed. Using both units at the same time showed them to be very similar although the MagSpeed sometimes showed speeds 20 to 30 FPS faster. I have no experience with the Labradar so I can't help with any comparison.
