Thanks, that was interesting - yet it is only suitable as dry sonar.
I found these at sparkfun and some places elsewhere.

Then i found some transducers for underwater operation, but they're not really
satisfying, as they are expensive and complicated to use :/

I'm a bit puzzled by that since there are (even cheap!) commercial fish finders
with great useability and resolution...

Look at this bad ass:

Okay, 1 kW is way more than i really need and have at disposal ;)

I found this: http://explore.mohodisco.com/boat.pdf
which is quite interesting. But as it seems the guy just picks up depth-data (no
more) via serial from such a hummingbird fishfinder. Its a start, but i'd rather
have e.g. linescans (with a good resolution) from the underwater surface..
