Some anglers praise forward-facing sonar, others say high-tech fishing ruins a day at the lake - KFIZ News-Talk 1450 AM

Forward-facing sonar is changing how anglers scout the water by delivering real-time images of fish and their surroundings beneath a boat. Typically mounted on the bow or stern, these devices can be configured in full setups around $2,500 and, according to Garmin's Dave Dunn, attach to a trolling motor to reveal exact fish locations and even let anglers cast directly toward them, though mastering the display takes time. Minnesota anglers including Terry Rehm say the tool is invaluable for maximizing limited lake time. Nationally, tens of millions of people fish recreationally each year, elevating the influence of this gear on the sport's future.
