LIVE TIME: After using a console-mounted screen to scan a west-metro lake last weekend, Steve Pennaz deployed Garmin’s LiveScope system (in perspective mode) to zoom in and search potential fish-holding structure in real time. As forward-fishing sonar becomes more common on state fisheries, some anglers, guides, and biologists are analyzing what it effects it could have on fish populations. (Photos by Rob Drieslein)
