as far as i think proper casing using plastic thin cover will not block sonar waves ,, give it a try.
This is a discussion on Getting Sonar sensor to work under water within the Electrical & Electronics Engineering forums, part of the CE : Technical Discussions category; I wanted to be able to use a sonar sensor such as this: SparkFun Electronics - Ultrasonic Range Finder - ...

I wanted to be able to use a sonar sensor such as this: SparkFun Electronics - Ultrasonic Range Finder - Maxbotix LV-EZ0 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.

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