Marine Electronics Ltd is presenting its new Dolphin 2D sonar at Oceanology where designers of small AUVs and ROVs are expected to be impressed by its performance and compact size. The new sonar was first shown to the industry in prototype form a year ago. Since then further design, development and testing has been completed and Marine Electronics is now able to demonstrate this impressive new product to potential customers who have been waiting eagerly since its preview.
The new Dolphin 2D is a 720 kHz system that has evolved from the company’s existing Dolphin 3001 model while introducing several new key benefits. Its compact size and light weight now make it an ideal choice for use on small ROVs and AUVs as well as for other applications on surface craft. Its versatility and ease of use is also improved by an Ethernet connection to the underwater unit.
A one-piece composite ceramic unit with 96 elements gives the new Dolphin 192 acoustic beams that create a 120 degree horizontal display. With a low power consumption of less than 15 watts the sonar can provide clear images at 30 frames per second for very close range work at less than 1-metre, or for long range imagery up to 100 metres at 7.5 frames per second. It is able to provide the clearest imagery at most ranges but if customers need a 2D sonar for targets at a specific distance the basic model can be adapted to meet their needs. The new sonar also contains a nine-axis MEMS motion sensor and requires no surface image processing. This means that what leaves the unit via its Ethernet connection is the image that the user sees.
The new Dolphin 2D now joins a range of sonar products developed by Marine Electronics Ltd. The company is based in Guernsey, UK and is well known for its ability to design and build specialised acoustic products that are tailored to meet the specific needs of clients around the world. Visitors to the company’s stand at Oceanology will have the opportunity of discovering the full specifications of the new sonar and discussing how it might meet their needs for high performance technology at a competitive price.
