Your shot timer dies on the third drill of the day. Now what?The Training Vault is built around the battery no other vault in the line carries - the 9V that runs your shot timer. Around it sit spares for the rest of what a training day actually drains: the AA and AAA cells in electronic hearing protection, the CR123 in your weapon light, and the CR2032 in your pistol red dot.Every cell type gets its own dedicated slot, so you can see what you have left at a glance instead of digging through a bag pocket full of loose batteries and torn packaging.What it holds1x 9V - shot timers2x AA and 2x AAA - electronic hearing protection2x CR123 - weapon lights and magnified optics3x CR2032 - pistol red dotsSpecificationsDimensions: 3.5" x 2.5" x 1.75"Material: PLA 3D printed polymerClosure: Magnetic locking systemDesigned, developed, and 3D printed in the USACompact enough to live in a range bag pocket and stay there between sessions.
