With PRO Fire, you've got what it takes to shoot a show like a true PRO. You can link ANY fused firework item to the control box. Just press the button on the remote to ignite the item, and you've reached fireworks technician status! Faulty lighters or too much wind won't get in your way anymore. Now you can light the fireworks with the click of a button, and the remote will work up to 500 feet away! It doesn't get any more sophisticated than this! This PRO Firing System is capable of 6 connections all on this small remote controlled firing system and run specifically on 8 double A batteries, so no cords to worry about.
