Johnson Outdoors Announces Patent Approved for Innovative Humminbird(R) Side Imaging(R) Fishfinder Technology

RACINE, Wisc., Jan. 26, 2010 (GLOBE NEWSWIRE) -- The U.S. Patent and Trademark Office has granted U.S. Patent No. 7,652,952 to Johnson Outdoors Inc. for the Humminbird® Side Imaging® technology. The approved patent protects Humminbird's Side Imaging® sonar systems from unauthorized copying.

"Our Side-Imaging sonar technology is one of the most heralded innovations in the marine electronics industry in decades," said Kelly Grindle, Group Vice President of Johnson Outdoors Marine Electronics & Watercraft. "It is a game changer for anglers who demand the best equipment available to help locate and catch more fish."

Humminbird first introduced Side Imaging sonar in 2005 in two of its 900-Series fishfinder models. Spurred by consumer demand, Humminbird expanded its offering of Side Imaging models to its 700-, 800-, and 1100-Series™ product lines.

Side Imaging sonar produces dramatically detailed and recognizable images of underwater objects and the bottom. These images allow anglers to pinpoint habitat, structure and drop-offs, which are prime holding areas for fish. With a coverage area of up to 480 feet side-to-side, anglers can search more water in less time to find the most promising areas to fish.

"Humminbird has created an entirely new sonar category in Side Imaging technology, and we have been very thorough in our product development and patent process to assure that our technology is sound," said Grindle. "We continue our efforts to enhance Side Imaging technology and will offer more features in the near future."

Sonar imaging system for mounting to watercraft

Abstract
A sonar imaging system for a watercraft is disclosed. The sonar imaging system comprises a transducer coupled to the watercraft and having at least one side scanning element and at least one bottom scanning element, an electronic control head unit coupled to the transducer and configured to display sonar images. The downward acoustic elements may be circular and the side scan acoustic elements may be rectangular. A software filter may be provided to remove noise generated by a spark plug or other operation of a motor for the watercraft.

Lowrance watercraft coupled transducer only has 2 side scanning elements.
Bottom element is in a separate transducer.

Thanks, I saw that in the lowrance release as it had to affix to an existing unit. Two transducer may not be the way to go.  Keep piling it on HB.  you guys have a great product.

RGecy:
It could be argued that the Structure scan is actually a bottom scanning element!  It does not say specifically it has to be a 2d or for depth reading only!

I think they have a pretty good case.  It will certainly be interesting.  My bet is they will settle before it goes to trial!
