D/26/BB

D/26/BB
  • NEAR OCTAVE BANDWIDTH
  • OMNI-DIRECTIONAL RESPONSE
  • EFFICIENT TRANSMITTER
  • HIGH POWER PROJECTOR
  • DEEP WATER CAPABILITY

The D/26/BB is a highly efficient, omni- directional transmit and receive transducer, with a 3dB bandwidth from 21 kHz to 47 kHz. Ideally suited for use in low frequency noise systems, long-range transponder applications and long range voice and data communication. 

The robust construction enables the transducer to operate in extreme underwater environments. 

The D/26/BB is available with or without acoustic calibration which is traceable to National Standards.
