Vic gets his amazing "unconventional" DI pics from mounting the xducer at an angle...so the the fan beam is "sweeping" in front of him...(similar to what SpotLightScan is accomplishing but Vic's is only 1 DI fan beam instead of 2 fan beams like SpotLightScan)..
I'm sure Vic will check in soon and offer his technique here ...
The interesting part of this type experiment is that the fan beam can be "aimed" ...therefore giving the user a general understanding of where the echo targets are located in relation to the boat...
