Default Furuno Doppler Radar

I'm thinking about adding radar to my TZtouch system. I'm going with the dome. How much better is the doppler radar?

I have had both the DR4D and the DRSNXT on the same boat. For my use- navigation - hands down the NXT is better. Target tracking and ARPA work better faster and more accurately

Great, thanks for the information. It's always better when you hear the results from an actual user.

This is the DRS NXT, before I got the SCX-20 heading sensor, I am using a Airmar GH2183 heading sensor in this screen shot. I have used the NXT on TZT and now exclusively on Timezero 4.0 Pro (PC and 17" touchscreen)

I had the DRS4D (24" UHD dome, not the smaller 19" DRS4DL+) and now the 24" NXT. I would maybe give a slight edge in long range target painting to the 24" UHD over the 24" NXT. However the NXT is better in every other aspect and at ranges most people would use a dome. The features and auto settings make using radar simple despite high level of functioning.

With NXT you get target analyzer, which paints objects moving at 3kn or more that could be threat a different color than stationary or object moving away for your heading. It will even paint storms red, the threat target color, that are moving towards you so you dont have to continually follow the storm to see if it is moving towards you or away from you. It has a rain mode that allows you to see hard targets in the rain more clearly without manual adjustments to deal with the rain clutter. The radar auto acquires targets (true ARPA) showing their speed and direction. It has Rezboost that works very nicely in shorter ranges at giving even greater target separation and clarity. It also has an auto bird mode that is a simple activation without manually adjusting the radar to find clutter of small targets. I regularly effectively use it at ranges of 2nm when running to find fish. While how power stabilizing binoculars see further and confirm targets it is nice to not have to set down an look when the radar gives me a 4-5nm swath of water coverage. All of these auto settings and features are available to use with a simple "upswipe" on the TZT2 and TZT3 screen.

Given that the costs are about the same for the for the DRS4D and NXT. It is a no brainer to go with the NXT. It is also well worth the extra $$ for the features of the NXT over the DRS4DL+ if using radar is important to you.
