I want to fit a barometer in my new boat. I am looking for one of the electronic type as I want it to hold and display recent history (a few days worth?) of air pressure. I would also prefer it to be powered by internal batteries as I do not like the idea of even a minimal permanent drain on the boat's batteries. Any suggestions will be very welcome and much appreciated. Thanks
 
I have one of those too and I like it, however, this new upgraded model was presented at last Paris Boatshow, and will likely be available during the nex few months, price supposed to be around 100 euro

I personally prefer the new one's display of pressure data, pixel by pixel, whereas in the former model there were the two dots near to each other which are not so nice /forums/images/graemlins/cool.gif
 
No need to spend a fortune.

Aldi have two different styles, both change from £20. I got one to replace the clock & anaeroid barometer on Jissel & was so impressed I got another for home. That was 3 years ago and both are still going strong and to within a millibar or two of the pros.
 
I have the nasa marine meteoman. It is a precision barograph with a rsolution of 1mB. It shows a graph of pressure for up to seven days. It runs on ships supply but has a power save mode which draws virtually nothing from the supply. It also has many other features including a graph of rate of change of pressure over the past 24 hours. Perfect for making weather predictions.
There is an option of a wind speed unit (or it can connect to an existing wind speed instrument) then it shows wind speed and direction and an anemograph of wind speed over seven days.
It's on nasas website under meteoman and costs just over £100. Well worth considering.
 
For a real cheapie LIDL had them recently at 15 quid. Quite tall say 10 inches with read out for 24 hours. Ours at home seems to agree closely with the Dartmouth on on the web.
LIDL will probably have one again soonish.
Make sure though that it has real millibars and ot just silly graphics.
 
My Vion A4000 is brilliant and it had an audio alarms for about 2 minutes when the pressure changes suddenly (greater than 0.4 millibars or something) anyway, that is pre-set and it always alarms about 2 hours before a 'blow'.

Shows trends too.

Absolutely brilliant /forums/images/graemlins/grin.gif

. . . . cost about sixty quid if I remember rightly?
