[MARMAM] Recommend a hydrophone please?

The Public Education Program at the Bamfield Marine Sciences Centre is looking to purchase a simple hydrophone set-up for teaching purposes. We would love to hear your recommendations for durable, water-proof systems that can be amplified enough for students in an uncovered vessel to hear from several meters away (in the pouring rain!). It would be a bonus if the quality was good enough for recording but not absolutely necessary. Please contact Anne Stewart, Public Education Coordinator, Bamfield Marine Sciences Centre. <astewart@bms.bc.ca> -- Anne Stewart Public Education Program Coordinator, Bamfield Marine Sciences Centre, 100 Pachena Rd., Bamfield, BC, V0R1B0 p: 250.728.3301 ext 226 f: 250.728.3452 astewart@bms.bc.ca
