I would like to buy a hydrophone to listen to marine life. Any body have any experience or ideas?
I just put ear to paddle
My carbon Greenland Paddle transmits sounds well. Wood’s not bad either.
Ear to hull might work too, but I need more Yoga for that…
Sea Kayaker mag (Aug 98) had an article on “A Twenty-Dollar Hydrophone That Anyone Can Build” with most parts available at Radio Shack. Pretty easy to build - I ended up building 3 of them. Might search their www site for the plans; if you can’t find 'em (and are interested in them), let me know & I can provide. Great for listening to dolphins… as long as the jet skis aren’t around!
