Battery / Connector box

 power not required

† Requires a preamplifier with 100MOhms input impedance, such as the Reson VP1000 (PDF) or Reson VP2000 (PDF) preamplifiers. If a preamplifier with 1MOhms input impedance is used, such as thePC200 (PDF), then the low frequency -3dB point will be at 60Hz instead of 0.6Hz and the -20dB point will be at 6Hz instead of 0.1Hz.

‡CR3 hydrophones are individually spot calibrated at the factory; calibration guaranteed between -5ºC and 30ºC.
