Equipment for underwater acoustics:
For research, marine biology and cetacean research. Development in laboratory facilities. For critical or extreme weather conditions. For Fishery authorities control of acoustic pingers on fishing equipment in regards to EC regulations.
- Hydrophone amplifiers and accessories
- for research and underwater sound recordings ex. of dolphins, porpoises and whales
- Acoustic pinger detection
- Hydrophones
- Power amplifier for driving an underwater loudspeaker
Hydrophone amplifiers
Our Hydrophone amplifiers are for professional use with high performance and quality. We have several models with different features and sensitivity. The more sensitivity the more the cost. Define your purpose to determine which model is best for your project.
Hydrophone Categories in regards to use:
- Fisheries inspection and control. Detection of acoustic pinger in regards to: The council Regulation EC No 812/2004: "concerning incidental catches of cetaceans in fisheries and amending Regulation (EC) No 88/98"
- Underwater acoustics research and sound recordings. Cetaceans sound recordings and research
- Fishermen. Detection of acoustic pinger

PD 1102 Acoustic Pinger detector
PD 1102 (etec) Pinger detector or Sonar Detector is the ultimate Underwater hydrophone Listening Amplifier and Acustic Alarm Detector. Also called Pinger Detector or Click Detector. State of the art in hydrophone amplifying.
Applications:
- detection of acoustic pinger
- fisheries inspection and control
- cetacean sound recording
- underwater acoustics
Fisheries inspection and control
The PD1102 Pinger Detector Hydrophone amplifier is developed especially for detection of acoustic pingers for fishery authority control in regards to: The council Regulation EC No 812/2004: "concerning incidental catches of cetaceans in fisheries and amending Regulation (EC) No 88/98" The PD1102 Pinger Detector is tested and recognized by german fishery authority.
PD1102 Pinger Detector System overview
the pinger detector system consists of:
- etec PD1102 Pinger Detector Amplifier
- Shoulderbag for the pinger detector
- optional WITH or WITHOUT TC4033 Reson hydrophone
- A set of closed aerodynamic headphones
- loudspeaker for presentation of the testresults (pocket loudspeaker A100)
- Complete system packed in a watertight suitcase, type PeliCase1500BK

Hydrophones
Hydrophones are used for picking up weak sound vibrations under water and the signal must be amplified by a high impedance hydrophone amplifier in order to convert the extreme high output impedance in the hydrophones piezoelectric ceramic into a low impedance signal which can be handled by commonly available signal processing equipment.
Dolphin sound recordings
Hydrophones and amplifiers are used for studying underwater acoustics and monitoring of sonar and communication sound signals from dolphins, porpoises and whales and detection of acoustic pingers. Detection of cetacean clicks.
