    Shock and Awe! I had no inking that any of these concepts were out there, much less available at the push of a button. Once again, you justify your position at the head of the line each morning, Ben!

    Ben,
    We advise our customers that using True Echo Trails in True Motion or Course Up mode is by FAR the best and fastest way to see the vessel inter-action and improve situational awareness around your vessel.
    The True Echo Trail feature is singularly one of the most under-utilized, yet most important aspects to radar navigation for the average customer.
    I have personally seen more than a few knowledgeable Furuno radar customers use this feature to determine who is tracking their positions in tournaments and in-turn, they use this feature to spy on competitors as well. it is also very useful when traveling with a group of friends. On the contrary, tracking individual ARPA targets requires constant viligence and is not nearly effective in this respect. The True Trail feature is a “Set-It” and forget it mode that will instantly provide tracked target and other details at a glance of the radar display.
    Combining True Trails with Radar Overlay in a 3D perspective showing the actual NOAA Raster/Vector Navigation chart was a breakthrough for Furuno with the NN3D Product Line.
    Thank you for the lucid explanation.

    Ben,
    What heading sensor are you using with each of these for the MARPA to work correctly?
    Also what is your take at the Raymarine 18″ Digital Dome vs the 18″ HD Digital Dome?
    Thanks for all your work on these units,
    Chris

    Chris, I’ve been using a Maretron SC200 compass on a NMEA 2000 network to give heading to all the MFDs. The Airmar PB200 on the same backbone also delivers good heading info, but I stupidly mounted it level with, and too close to, the magnetron radar stack. It reacts badly to the radiation sometimes, so I turned its heading output off (until I remount it in a better spot).
    I like the true color on the Raymarine 18″ HD dome; it helps to interpret targets and it shows rain beautifully. But other HD features, like dual range and auto speed control, await a software update. It’s also going to cost about $1,000 more than the Digital 18″ dome, putting it up in Furuno UHD territory. The Digital dome should do True Motion and trails similar to the screen above, aside from the colors.

  5. I concur with your comments about target trails. I use them often. Entering a crowed anchorage at night they may be dozens of anchored vessels not a threat and one slowly moving monster container ship. It’s hard to pick out the one ship underway against shore lights. With true trails you can spot the one moving ship quickly. It is also useful when encountering fishing fleets when there are too many boats to track individually

    I find the SIMRAD BR24 broadband radar very interesting with its close distance detail and low power consumption. I have not been able to find an 8″ screen sized display/multifunction unit that offers MARPA. Is there one coming? Have I missed something?

    Rick, The Simrad NSE8, just about to come out, can do MARPA with Broadband Radar. I’ve been testing a prototype NSE12, and like it quite a bit, but have only had limited MARPA experience with it so far.
