Good info so far on the paddle. The Corrvrecken is a high angle blade shape which is more powerful but also more fatiguing (lightweight materials like carbon fiber will help to offset the fatigue factor). The Kalliste is a low angle alternative with a longer, narrower blade. We stock both paddles at OEX if you'd like to check em out.
If you have any questions on installing the transducer give us a call, we'd be more than happy to walk ya through it.
