RoxAnn was developed for scientific use and has been routinely used in many seabed mapping studies with applications as diverse as dredg- ing, fisheries habitat management, environmental pollution control, sea grass and coral population research and assisting hydrographic offices in the generation of navigation charts. The RoxAnn Groundmaster GD-X is a stand-alone system, using a small dual frequency fish-finder sonar as its host. Built into a watertight and stur- dy case of 200 x 110 x 60 mm and weighing only 4.5kg, it is consider- ably smaller and lighter than the pre- viously available version.

Its hand carry AC- ROV underwater inspection system was operational for the full three show days and kept the staff busy with an overall average of nearly six hands-on presentations per hour. Visitors were given a quick demon- stration of the micro ROV's capabili- ty in the eye level glass tank before being let loose to try it themselves. This was followed by a run through of what you get for your money in a single hand carry case, ready to oper- ate system. A wide screen TV had the new AC-ROV 'Demo on a Disc' on continuous play to inform those visi- tors waiting in the queue and for fin- ishing off a visitor presentation with live underwater footage. The 'Demo Argonaut Laptop Receives ABS and IMO Certification Argonaut Computer debuted what it calls the world's first marine lap- top computer certified by the American Bureau of Shipping and compli- ant with International Marine Organization standards. The new Ranger model 1500T/TXL is a rugged, sunlight readable, high performance Pentium laptop computer certified for use aboard naval and commercial vessels worldwide. The Ranger has been designed for durability, compati- bility and safety in some of the world's most demanding marine, military and industrial environments. "The 1500 performed flawlessly in all stress tests," said George Kioutas, President of Argonaut Computer. "We have devoted a decade of marine laptop experience to producing the ideal light- weight, powerful and high performance system for both professional and recreational marine use." The Ranger laptop was also tested and certified to meet the stringent requirements of the International Marine Organization, rating IEC/EN60945. This standard relates to electromagnetic emission and immunity standards for equipment used on the bridge of commercial and naval vessels. Ordinary computers emit radio waves that can potentially interfere and cause dangerous malfunctions when placed close to navigational and communication electronics, typically found on the bridge of commercial and naval vessels. The Ranger was specifically engineered to reduce harmful emissions and passed the IEC/EN60945 standard without malfunction. Magnetic interference is also a concern, addressed by the 60945 test procedures to establish that the device is immune from ship borne magnetic energy. The Ranger was determined to be immune and performed without malfunction when exposed to high levels of magnetism.
