weather instruments

Do any of you know of a good digital barometer, anemometer, wind direction, temperature, humidity combo with sensors that connect by cable and run on 12VDC?

They make a handheld, called a kestrel 4000 that does most of that... Maretron also makes a weather station type kit for marine use that might be what you're looking for.

No, but I have a Speedtech recording barometer/temp/humidity combo that hangs in my pilothouse and takes 4 AAA batteries that lasts about a year. I've adjusted it for local height above sea levels and have found it agrees closely with the local weather stations, so much so that I have to adjust it when I take it home, which is a further 150 feet or so above the lake.

I guess what I am getting at is beware of putting all your eggs in one instrumental basket. Humidity, temp and barometer can all be read inside the boat...get an inside/outside thermometer for 15 bucks from Radio Shack if you need it...but apparent wind and speed you need on deck AND at the masthead to make proper decisions about sails, reefing, helming, etc. Go with a bulletproof masthead unit that does two or maybe three things flawlessly, because if your wireless Davis weather station is blown off the masthead, you are pooched, as the kids say.

Thanks for your guys feedback.

I probably should explain a little more about what I'm looking for. I'm looking for a weather station with outside mounted sensors for my sailboat, sensors connect to the station by cable (so no batteries in the sensors) and runs on 12VD. I have found a couple of companies that make somthing near what I looking for. La Crosse Technology WS-2310TWC Professional Wired/Wireless Weather Station for $109.95. the station comes with a weather vane, barameter, anemometer sensors, 32' cable extendable to 64" and runs on 3 AA batteries. If I have time I guess I could make a voltage divider and run it off the boat batteries. The other is the Davis Vantage Pro, a little pricy for me at $500 to $900. Does anyone have any experience with the La Crosse?
