Choose which tree--yours or your opponent's--to launch off of with one of Dedenbear's Crossover delay boxes. Use the regular delay feature to launch against your own tree, or flip on the crossover when you want to leave off of your opponent's tree. You can even use one box to leave off of your tree's top bulb, and one to leave off of the bottom one. The boxes feature push-button thumbwheels (0.000-9.999) and a toggle switch to bypass the box completely. The cross over delay boxes can be used with any transbrake up to 45 amps, and on any ignition system. Want the Dedenbear advantage for a win? Just dial it in!
