Structure Scan: Fwd Looking Sonar ?

[mikefossl]

Now that Lowrance has added a couple of thru-hull transducers what do people think of using that technology as a forward looking sonar? Is a 250ft side scan (or forward scan in this case) range enough ? This would be about 6 boat lengths for us. I imagine myself feeling my way into a coral head infested lagoon with this might be pretty cool. The sample screen shots show enough resolution that I could see how well the anchor is set without risking swimming with the crocs.

Thoughts?
