Product Description

The Buzz-mo® BCT-4 Bridgewire Continuity Tester is precisely engineered to safely indicate a complete bridgewire circuit in commercial electrically fired initiators, detonators, matches, and pyrotechnic devices manufactured following I.M.E guidelines*.  *The Institute of Makers of Explosives (I.M.E.) recommends that the minimum ignition current of an electric detonator manufactured by its member companies be not less than 250 mA.  The lowest ignition current documented by the U.S. Bureau of Mines was 173 mA (USBM Contract #H0210068). It is your responsibility to verify that the device you are about to test complies with this standard before you begin!

Features & Specifications:

Manufactured in the USA

The ORIGINAL and best haptic continuity tester!
- Strong vibration provides positive indication, even in direct sunlight and noisy environments
- No more squinting or hand-cupping to try to see an LED in bright sunlight

Outstanding safety factor
- Under 60µA (micro amps) max current draw; less than 1/800th the max allowable safe testing current of 50mA, as established by MSHA
- Testing circuit protected by 50mA fuse

Very easy to use
- Just touch the bare leadwire ends against the oversized contacts
- A vibration indicates an intact bridgewire circuit (does no indicate resistance)
- No vibration indicates an open bridgewire circuit

Oversized stainless steel contacts
- The largest stainless steel contacts available on ANY model of tester
- Corrosion resistant stainless steel contacts are available blackened for tactical operations
- No fumbling, easy one-handed operation

Extremely sensitive
- reads through thousands of ohms of resistance
- perfect for reading an entire trunk following individual tests

Operating temperature range
- 10º to 158ºF (65º to 105ºF optimal – do not allow to freeze or overheat)

Rugged, sealed ABS case
- Available in Safety Orange, with natural stainless contacts or Tactical Black, both with blackened stainless steel contacts
- Dustproof; waterproof; and shockproof

Internal CR-2477 battery
- Life expectancy of approximately 50,000 1-second tests, or about 3 years under optimal conditions (can be factory replaced for a fee)
- 2.7” wide x 5” long x 1.4” thick; 11.5 ounces (with battery)

Small and lightweight
- 1¼” W x 1¾” H x 1” L; less than 1 ounce (31.8 mm x 44.5 mm x 25.4 mm; less than 28 g)

90-Day Factory warranty against manufacturing defects
