SQ26-H1B Hydrophone
SQ26-H1B Hydrophone
The SQ26-H1B is a general purpose hydrophone ideal for whale watching and full audio-band signal detection. It can also be used as a contact microphone or low cost geophone. The SQ26-H1B hydrophone is the base for our SQ26-H1 system.
The SQ26-H1B is a great kayaking hydrophone and a wonderful recreational boating accessory.
An excellent option is to pair the SQ26-H1B hydrophone with a bluetooth speaker – chose from headphones or a waterproof speaker (mounted with a suction cup capable of sticking to the outside of your kayak or top of your boat deck).
