Musashi 8 Marq/Onyx board with 4CTM technology, supporting 4 eyes and the Draxxus Pulse RF transmitter

Now the "stock" board in every Bob Long Closer!

The Tadao Marq/Onyx board is a drop-in upgrade for the latest Bob Long markers including the Marq 6, Marq 7, Mummy, Rapper, and Closer. As the first board to contain Musashi 8 software and the licensed 4CTM technology it includes integrated support for the 4 Eye boards, utilizing both top and bottom eye sets to ensure the fastest rate of fire and lowest chance of chopping. The eye logic is nothing short of amazing as it calculates the incoming feed rate of paintballs from the loader, automatically switching between the top and bottom eye sets as the flow of paint changes.

The Tadao Marq board has redesigned hardware, providing superior battery life, increased solenoid power output, and a larger and faster microcontroller capable of handling the new Musashi 8 software. It also includes a hard mounting point for the Draxxus Pulse RF transmitter, and a plug-and-play wiring harness. This allows the user to permanently mount the transmitter for less clutter in the grip frame, or with the use of the wiring harness, quickly switch the transmitter between multiple markers using Tadao electronics.

The circuit board is the most important part of any electronic paintball marker, and upgrading it can potentially change all the performance characteristics. Tadao's leading edge Musashi 8 software provides the user with the ultimate in adjustability and speed.
