I have been evaluating the MIOPS Smart Trigger and have been experimenting with the sound trigger feature.
I set up a small water-filled balloon with a Cactus RF60 Flash behind to backlight. The RF60 was triggered via a Cactus V6 II plugged into the MIOPS Smart.
I burst the balloon with a shot from an air gin.
The MIOPS Smart has done a good job of triggering the flash at about the right time. The gun was fired about 4 feet from the balloon which would have introduced a short delay.
This shot has caught an odd moment where the pellet can be seen entering the balloon but the burst has not kicked in
