FARSOUNDER'S LATEST 3D SONAR SYSTEMS, THE 500 AND 1000, WERE LAUNCHED AT THE MONACO YACHT SHOW WHERE SB SAW THEM IN ACTION

The new 1000 is FarSounder's flagship navigation sonar, which offers users 3D forward looking navigation out to 1/2 nautical mile (900-metres) ahead of the vessel, while the 500 gives navigation information out to over 1/4 nautical mile (500-meters). Another advantage of the 1000 is the ability to select between a wide field-of-view or an extended range mode. The system can operate with a 90º field-of-view out to 500-metres range or a 60º field-of-view out to 1000-metres range.

Both forward looking sonars are able to generate a complete 3-dimensional image with a single ping. The 3D imaging really excels in situations where charts are poor, the bottom depths change with the seasons, the obstacles are transient (such as shipping containers), or the channels have filled in.

Collisions and groundings cost a lot of money, which is why - in FareSounder's continuing efforts to improve user experience - they have also recently added chart overlay of in-water targets to these navigational products. This enables users to more quickly and easily make the jump from what they see on the sonar's display to where potential navigation obstacles are located.

Chief Executive Officer of FarSounder, Cheryl M. Zimmerman, highlighted the benefits of the chart overlays to SB, "I believe that in addition to the improved procvessing that is included in these new products, that the addition of our chart overlay capabilities (over the C-Map Charts) brings the understanding of the marine environment in front of vessels to such a high level now that even a non-mariner will quickly see the benefits to these systems."

The chart overlays mean that as the yacht moves, all in-water targets are tracked from ping-to-ping and their geo-referenced locations are plotted on top of electronic nautical charts inside the FarSounder software.

Installation of the new FarSounder 500 and 1000 navigational products can be on yachts ranging from 20 to 200m (66 to 656 ft).
