A traditional BOB is intended to be used for voltage measurements using multi-meter or oscilloscope. An SBOB is primarily designed to be used for current measurement.

SBOBs for current measurement are traditionally used by research- and development departments and ‘flying doctors’, staff especially trained to locate complex errors in vehicles.

Wiretronic develop and produce SBOBs up to 248 pin configurations. Custom designed SBOBs are developed and produced to meet specific demands.
