I bought this in April of '21, and used it only a couple of times at some Bandit launches - it's like new, except for some corrosion on some of the alligators.
I've attached some pictures below, but you can read an exhaustive description of it at https://www.apogeerockets.com/Launch-Accessories/Launch-Pads/Impulse-fiver-SPORT-Bundle, where the bundle of pads and controller is sold (I don't have the pads).
In summary, it's a relay-based 5 pad controller that uses a jump battery for current. Safety and sirens at both ends, with the ability to easily drag race. There's a resettable fuse/jumper in case the current gets out of hand. 50' of ethernet connecting the two controllers, and different length ignitor leads with alligators and bananas. The cases look to be built from cellular/foamed PVC - they're light but very strong.
Thomas' web presence has been cut significantly since the passing of his wife, so these are now built to order. I don't know what they go for, but prior to moving the site/business since the tragedy, he was selling these for $575. I'll sell this for $250 here before going to eBay. A jump battery is included, though not pictured - it's more robust than what is sold with new units.
