The advantage to the accoustical chronograph would be for those interested in recording bullet velocity way down range, in order to confirm their bullet BC out of their own rifles. I've taken my conventional Oehler chronographs out to 1000 yards a dozen times in the past and recorded bullet velocity. It can be done, but the window area the bullet has to pass over to get a recorded velocity is so small, it's quite challenging. I protect the skyscreen rail and skyscreens with AR500 steel so I don't ruin all the skyscreens with an errant shot. Currently I have three bullet splat marks on my AR500 plate. If there's any wind at all it's easy for the bullets to pass left or right of skyscreens - which results in no readings. It can get discouraging because I've got to travel the 1000 yds down to the chronos after the shots to confirm I'm zeroed and obtaining velocity readings. It usually takes a few shots to get the bullets passing just above the skyscreens.
The available window area which will result in recorded velocity over the accoustical chronograph is huge, in comparison. Almost all bullets fired would likely result in recorded velocities, unless the wind conditions were miserable.
I'm thinking of getting one to set up down range. I can use my current chronographs near the muzzle where it's easy to get velocity with each and every shot fired. Set the accoustical chrono out at 500 or 1000 yds. With those distant downrange velocities and a muzzle velocity, one can calculate a very accurate BC for their hunting bullets out of their specific rifles. Which is pretty comforting for me.
