Sonar looks like an attractive option. My reservation is not the price because it looks like a once and done for the season option. But, I'm not sure if I want to wipe out all vegetation completely for the fish's sake. My pond is sort of a kidney bean shape, with the narrow area separating the swimming area from the other half, where I thought leaving some vegetation would be beneficial. Each half is about a half acre.

My questions, do you think sonar could be effective on leaving some life in the far half, and how safe is sonar for fish and swimming?

Thanks for the input.
