This new MXC bag combines both the recorder and receiver compartments to form one ridged structural design. The new style of MXC provides a much stronger frame and offers greater support. The bag has two large pockets on either side, perfect for an NP1 type battery or left and right transmitter sends. Located within these pockets there are also additional transmitter attachment points.Extra storage space has been created within the double layered Vinyl window. This allows the user to store some small convenient items or frequency chart information.The MXC-833 is designed to allow the user to compress the outer section of the bag and create a smaller and more compact case.
