Reward #3: You are pre-ordering a Bat Sub KIT-PLUS edition, the flagship edition. This includes everything in Reward #2, plus one more Bat Sub CORE (the main adapter unit).

With a total of two (2) CORE units, you can keep one at home and take one with you. Or, you can connect the two CORE units together to extend the total reach of your Bat Sub. Each KIT has a built-in coupling feature to allow the connection. The extension will come in handy when the length of the battery compartment is unusually long. Please see our FAQ page for more information. Now you're sub'ing like a pro! ($5 shipping and processing fee pre-included)
