Item # 5213

The BB-75 is an advanced, compact high energy capacitive discharge blasting machine capable of initiating a minimum of 75 EBCs (tested through 340 ohms). Bridgewire and firing line continuity is testable through the integrated haptic (tactile feedback) circuit tester with redundant LED. Intrinsic safeties include automatic abort, internal shunt, boot-protected switches, touch-proof output terminals with downward facing inputs, and fuse protected testing circuit.
Blaster One
Manufactured by: CFX Devices
Model: BuzzBox 75
Product ID: 5213
Not MSHA certified - not for use in explosive or flammable atmospheres.
  • Proudly manufactured in the USA
  • 320 VDC @ 10 joules (min) firing energy (max output 340 VDC @ 13 joules)
    • Capable of firing a minimum of 75 EBC's connected via 3000' of two-conductor 18 ga. copper firing line (tested through 340 ohms).
  • Built in bridgewire testing circuit
  • The ONLY blasting box featuring a built-in-haptic (tactile feedback) bridgewire continuity tester.
    • Strong vibratory response provides positive indication, even in direct sunlight and noisy environments.
    • LED visually confirms continuity and doubles as a low-battery indicator.
  • Small and lightweight - 3.5" wide x 6.5" long x 1.2" thick
  • Easy to Use
    • Connect firing line to high-voltage binding posts
    • Hold down ARM switch to charge blasting circuit
    • Once the "Ready" LED lights solid (flashes during charge), press FIRE button to send high-energy pulse down firing line.
    • A loud bang and visual "poof" appearing from the far end of the firing line indicates a successful blast!
  • Intrinsically safe design
    • Internally shunted output terminals help protect EBCs from stray EMI - remain shunted until instant of firing.
    • Auto aborts the instant ARM button is released (prior to firing)
    • Bridgewire testing circuit limited to less than 5 mA (final circuit current may actually be less than 1/2 mA)
    • Touch-proof output terminals with downward facing inputs reduce risk of shock.
  • Rugged enclosure
    • Black ABS case with bright-red/orange rubber boot and sealed switches
    • Shock and weather resistant (not designed for wet use due to high-voltage output)
  • Optional accessories
    • Shock-tube initiator
    • Nylon pouch

This blasting machine tested at more than 125 2-ohm EBCs through 3000' of two-wire 18 ga copper shot line - conservatively rating it at 75.

The Shock Tube Adapter is still in development - though in the meanwhile it is possible to use the Wizard Arc on this machine. To do so requires modifying the Arc's spade connectors to banana plugs - and the higher output energy of the BB-75 may require the Arc electrode to be recoated with carbon from an ordinary #2 pencil between shots.
