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.
