Sonar pushes the limits

Innovation in marine electronics, no matter what the device or software, tends to advance in stages with technological leaps followed by incremental refinements. Over the past several years sonar technology has been a star player, moving ahead with more revolution than evolution and driving healthy sales for many brands. Below is part 1 of a two-parter that checked into the trend for Marine Electronics Journal.

Converting electrical energy to sound energy and interpreting the results isn’t new. In fact, the first sonar was patented in 1913 by Germany’s Alexander Behm. But sonar has made some noteworthy advancements, especially recently. Today, we have CHIRP, multibeam and live sonar with videogame-quality graphics and an outlandish reach.

Some units are really more of a commercial system but demonstrate what sonar can be. Take Furuno’s Omni CSH8LMK2 8L for example. With over 420 transducer elements, this system looks 360 degrees around the boat at individual targets or schools of fish nearly a quarter mile away. Meanwhile, Garmin’s Panoptix LiveScope and the new Lowrance ActiveTarget Live deliver game-changing resolution for shallower waters with "live” sonar with real-time detail.

Multi-beam units are popular, such as Furuno’s DFF-3D deepwater sonar, which fuses its fishfinder and commercial phased-array technologies. Raymarine’s RVX1000 delivers CHIRP, down and side scanning and their RealVision3D which is beam stabilization. Humminbird’s Mega Series leans heavily on multitasking too, including dual-spectrum CHIRP, down and side imaging, and Bluetooth networking with Minn Kota trolling motors.
