Humminbird side scanning, as good as it looks?
Last week I mentioned (relatively) inexpensive side scanning sonar, and here’s what I’m talking about. This 7” diagonal Humminbird 981c, which retails at about $1,650, is a conventional 750 watt dual frequency (50/200kHz) fishfinder that’s also able to scan sideways about 240’ out and 100’ down at 262kHz. The image on the screen (bigger here) is the left side of a scan, showing a submerged barge (distorted by the scanning dynamics) and a pile of dumped logs. You can see from the numbers that the depth was only 11’ and the scan is only looking out 30’, but there are more screen shots on Humminbird’s side scan page that show pretty good detail at somewhat greater range. Of course, these are all company images; has anyone out there tried one of these?
