Bill D. this is a Binocular I bought a while back. Celestron SkyMaster Giant 15x70 Binoculars with Tripod Adapter. It is a lot of Binocular for the price and is a #1 seller at Walmart online. I would think that viewing from 350 feet to your pond this would pick out the critters OK. This binocular is usually used for terrestrial viewing. Read the reviews. 1300 of them.

The downside is the Binocular is rather heavy and at 15 power the slightest jiggle will jar the view. But if you attach this to a trypod it might be what you want at a great price.
