The Ubertronix Strike Finder Pro II Camera Trigger dropped the intervalometer from the Pro and added the sound trigger from the Elite. Much like the other devices, this is an exceptional camera trigger that comes with three extraordinary capabilities that make it possible photograph things that would otherwise be extremely difficult to do. It comes with a laser trigger sensor, a sound trigger and Camera trigger (lightning or other high flash event). These sensors were selected based on specific feedback from other photographers looking for this capability. All you need is a DSLR camera and you're ready to go.
The Trigger was designed to capture lightning strikes either day or night. It uses microcontroller-based technology along with an infrared sensor to capture the most stunning photographs with complete ease. The device mounts onto the camera hotshoe, so you can walk away and let it do all of the hard work.
The Laser Trigger was designed to capture anything that breaks the beam from water droplets to people walking through it. Once the laser has been tripped, the device instantly sends a signal to the camera telling it to release the shutter. The shutter releases about 45-60 ms later, depending on the camera.
The Sound Trigger allows you to do high speed photography. The sound trigger attachment plugs into the side of the Strike Finder with an 18" cable. When it senses a loud signal, the device sends a signal to your camera to release the shutter.
