Re: NEXUS Instruments - Experience with?

We have a 1985 J27 that is serving us very well. It came with a Nexus Multi Classic 1000 package (as near as I can tell from pictures anyway) which is still working - sort of.

The depth gauge keeps chirping at us to warn us that we're at 3.5 to 4.2 feet of water. It seems to happen at any depth between about 35 to 42 feet - I've watched it move up the depth from mid teens through twenties, hit the mid thirties and go decimal on me, move up to the low/mid four foot range, then pop back out of decimal as it moves into the 50 foot range.

We're sailing in NY Harbor and the lower Hudson river. Tons of boats, including sailboats with bigger drafts than us . Not to mention the cruise liners. Clearly we're not in 3.5 feet of water. (The draft on this boat is about 4 feet or maybe 5 feet - we're NOT in 3.5 feet of water). Also, given both traffic and water quality (even though it's improving) we're pretty confident that we're not seeing schools of fish or algae or something interfering with the depth gauge. It seems to be software, not hardware related.

Has anyone seen this issue before? Does anyone know of a software update to the server or the equipment?

Tacking from side to side in the Hudson River, we move through that depth range (30-50+ feet) a LOT. The constant chirping is miserable, and for safety reasons we can't just shut it off completely. Any info or suggestions would be appreciated.

Re: NEXUS Instruments - Experience with?

Thanks guys!

I am convinced that Nexus is great but I ended up with a boat that has Simrad instruments

Salonas come with Nexus instruments but they can mount Raymarine if you want. For what I have heard on this thread I would stick up with Nexus.

I ended up buying an used boat that come with Simrad.

Now about Simrad.... well the 2002 raymarine plotter I had was faster then the 2007 Simrad I have now and I liked more the Raymarine instruments, with the exception of the autopilot that is really good.

I have a Furuno 2007 radar that is really crap compared with the 2002 raymarine I had. It has not even MARPA and without that a radar worth a lot less regarding its use.

From Nexus I have the binoculars they represent (Eterna). I had already on the other boat the previous model when they were "Silva". They are great with an incredible low light capability.

Regards

Paulo

Re: NEXUS Instruments - Experience with?

Slightly OT....

Would like to drive the steer pilot from my PC (for instance would like it to automatically give best upwind / downwind depending on current TWA and polars). Anyone know how to drive it through the NMEA interface?

Guess I might be able to have it drive to a waypoint and keep moving the waypoint from the PC - think that's possible, but it seems quite hacky and I'd prefer to just drive the dial directly.

I know that some of this is possible through the FX server but would prefer full control if available.

Re: NEXUS Instruments - Experience with?

Does anyone have experience with the auto calibration system? I don't seem to be able to get it to drive the steer pilot instrument, though the one on my laptop display does do something. Using the laptop is really awkward as it's below and can't be seen from the helm.

If you got this to work how and did the final calibration help accuracy?

Re: NEXUS Instruments - Experience with?

Sorry to resurrect this old thread.

I got a new nexus HPC compass, to fix an autopilot problem and things seemed to go well on our trip south, thousands of miles. Now, we are heading home, and our sailing is almost all downwind.

It's an Autonav, the AP 1500 that uses an original Nexus display unit.

I am struggling to get it to function. I have tried to incrementally adjust the calibration settings, but no matter what I do, the autopilot will hunt back and forth ever increasing until we are turned so far off the wind, we get overpowered. The problem is exacerbated in following seas when swell will turn our rear around.

Our boat is a 1974 Tartan 41, which isn't great downwind, but still...

Does anyone have an original nexus and can recommend some starting calibration numbers and then a good adjustment method. I can't seem to get the four setting right ><
