Getting Sonar sensor to work under water

I wanted to be able to use a sonar sensor such as this: #-Link-Snipped-# but I'm not sure how I would get it to work underwater. I'm thinking any sort of water proof casing I would put it in to protect the chip, would block the actual sonar signal. Does anyone have any good ideas on how to either make this work or suggest a product that would work under water? Thanks for any help.

    as far as i think proper casing using plastic thin cover will not block sonar waves ,, give it a try.

    Ok thanks. I think I'll have the casing made as thin as possible and see if that works.
