Marine Electronics Ltd will present its new Dolphin 2D sonar at Oceanology International. The new sonar was first shown to the industry in prototype form a year ago, and since then further design, development and testing has been completed and Marine Electronics is now able to demonstrate this new product to potential customers.
The new Dolphin 2D is a 720 kHz system that has evolved from the company’s existing Dolphin 3001 model while introducing several new benefits. Its compact size and light weight now make it suitable 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 meters 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.
