The J-24 I sail on has wireless instruments (TackTic). The masthead wind unit
has its own built in solar cell as do the instrument heads. All have been in
service for over five years now, with no problems. I don't think any of the
batteries have been replaced.

Subject: Re: Stus-List Nexus NX2 Instruments
Now that my season is over I am starting on my list of winter projects, one
of which is adding new instruments. I had been considering a Raymarine package
of speed depth and wind but the Nexus NX looks very good for my needs as well.
I won't have a chart plotter installed (only lake sailing) so I don't need the
capabilities that most of the listers would require. I sailed all summer with
an antiquated depth gage which I didn't trust and my hand held GPS. Didn't find
the bottom so thats good but I didn't like not knowing how deep the water was.
My first question is regarding the wireless wind transducer on the Nexus
system. Wireless is everywhere nowadays so I am sure that it isn't bad but I
wonder about things like maintenance and battery life. The Raymarine gear is
wired for all the transducers but I find it appealing not to have to fish a
cable through the mast. Any experience on the list with wireless instruments
and/or specifically this brand.
Second question, I have a speed transducer now as well which is worn out, and
a separate thru hull for the depth. What are the opinions of the list regarding
the single larger transducer or having separate speed and depth. I don't know
the diameter of the existing I am hoping to use the same locations if possible.
Can these thru hulls be enlarged?

I have the old Nexus instruments and have been very pleased with them. Put
them on the boat in 1999. Only failure was a knotmeter transducer. That may
have been due to my practice of removing the transducer after every sail. The
transducer had no stress relief where the wire came out of the transducer. The
wire or shield may have broken at the interface. I slipped a couple pieces of
heat shrink down the cable, shrank them at the interface then poured epoxy
around the heat shrink. Cured the problem.

Bob -- what instruments are you replacing? Speed/depth? Wind?
If you want true NMEA2K displays, you only have a few choices; Raymarine
i70 (technically SeaTalkNG, but talks to NMEA2K), Garmin GMI10, Furuno FI50
(not certified NMEA2000, but will talk to NMEA2K) or Simrad IS40. As far as I
know, the Nexus systems still use a central "server" that all displays and
transducers connect to (Nexus is now owned by Garmin). A true NMEA2000 system
would have all the displays and transducers connected to the NMEA2000 backbone.
Raymarine has a reasonably-priced way to do that using older non-NMEA2K
transducers; it's the ITC-5, and will accept inputs from older Raymarine depth,
speed, wind and rudder transducers, then put all that data into SeaTalkNG form
(also readable by NMEA2K). List is $265 (you can get for under $250). Add a
couple of i70 displays for $535 list ($460) and a SeaTalkNG cabling kit and
you're done, assuming you have the transducers installed in the first place.
Simrad has a depth/speed/wind package with all transducers, backbone
cabling and ONE IS40 display for a list of $1599 (you can get it for around
$1200). Add another IS40 display for a list of $599 (around $450).
Furuno doen't have a very good track record so far with their NMEA2K
instruments; you don't see too many around. And Garmin has the display, but
not so much for NMEA2K transducers.
Maybe others on the list have some comments on the Nexus systems; but
that's NOT going to be a true NMEA2K system as far as the displays go.

Over the winter, I will be shopping for a new instrument package to
replace the old Data Marine units on my 29-2.
I would prefer to install an instrument system using the NMEA 2000 /
NX2 protocol.
Does anyone have experience (good or bad) with Nexus instruments

The new "race box" sounds interesting
