Tiny and tough, this active condenser hydrophone is great for all kinds of underwater listening and recording. It is constructed from a shielded waterproof cable, a high quality metal output plug and weighted copper head. Recommended for capturing even the quietest ambient water sounds, including those in the ultrasonic range.
This hydrophone is low noise and high sensitivity with a frequency response range of approx. 20 – 20,000Hz with a useable frequency of up to about 100kHz. The microphone head measures approximately 1.3cm (0.5") wide and output is via a standard male 3.5mm jack. The total length is 3.1m.
Requires standard 2-9 volt plug in power. (Most hand-held recorders such as the Tascam DR-05 and Roland R-05 will provide plug-in power).
