Berthon’s electrical team has been busy fitting Raymarine’s new Quantum 2 radar to an array of yachts including this X442.
Retaining the core features of the original Quantum, the Quantum 2 features wireless networking and low power draw, making it especially friendly to vessels running exclusively on battery power. It also weighs less than a conventional magnetron radar at only 5.6kg (12.3lb).
The difference is the inclusion of doppler advanced technology, allowing you to clearly see whether a target is moving away from you, towards you or is stationary/anchored. You can also select from a choice of pallets to colour code your radar, for example, all inbound targets are coloured red with safer outbound targets being coloured green.
The below video gives you a good demonstration of how the Quantum 2 CHIRP Radar with Doppler Technology works with the colour coding.
This radar works by bouncing microwave energy waves off of an objective, just like any other conventional radar. Although this time moving targets send back echoes whose frequencies shift up or down from what was first transmitted.
For incoming targets, the frequency grows as the returning echoes are received more frequently as the vessels range from you decreases. For all outbound targets, the frequency drops as the returning echoes spread out as its range increases. Therefore giving you the display that you saw in the video above.
The Quantum 2 also features Raymarine’s new ‘True Trails target history’ display. This new feature permits you to see a historical ‘wake’ or line behind every chosen moving vessel. This extra information now makes it even easier to understand the movements of other vessels, allowing you to make smarter manoeuvring decisions to pass safely.
