Didn't know they did one of these and at an affordable price too!

I bet it works better than the other make as well

I can't raise much enthusiasm for a wind system that only displays direction in lumps of about 15 degrees.
To be any use, you want 1 degree resolution.

Looks like its based on the same old masthead unit that routinely sheds its rotating cups !
and thats affordable?..... maybe to you mega-rich people!

NASA?
Don't forget to factor in the cost of a mast ladder.

I bought the wireless mast head unit at the beginning of the season. It performs very well and, regardless what forumites say, has one degree resolution and isn't the same as their original unit.

The manual for the display does not say how you get a reading out of it to 1 degree?
I had clipper log and depth on a previous boat 12 years ago and had no problems, also a GPS repeater and AIS receiver on another boat.
More reliable than ageing B&G stuff in my experience, nothing lasts forever on a yacht....

That's very optimistic, I'd give it three days.

In my experience NASA stuff is pretty reliable and good value...unless it has moving parts. Nuff said.

The only Nasa stuff i have ever bought is a BM 2 6 weeks ago.
Impressed with it ( so far )

The picture shows a wind direction of 23 degrees - can't see how thats in lumps of 15 degrees.
I've got NASA stuff on Cobblers and I've had it on other boats. Doesn't seem less reliable than Raymarine to me.
I'm not planning to install a wind instrument - proper sailers use 'woolies'.

Isn't it saying 23 knots?
If it is meant to be a direction it's a bit useless - who sails by numbers rather than an arrow (vane/pointer/dial/burgee) pointing the right way?

Errr... isn't that the wind speed???

I hope the solar cell is not on the top side as it will rapidly become a shelf for supporting deposit making Shite Hawks....
83 days use before Guano clearance is required if fully charged....

Thanks for pointing that out! So isn't the direction arrow the direction of the wind?

Yes - but it doesn't move smoothly like the pointer on most wind instruments. It's a segment of LED which is either on or off, and when the wind moves out of its segment it goes off and the next one round comes on. I think the "tail feathers" on the other side are made by turning on an adjacent pair (or rather, two pairs).
The segment width looks to be 7.5 degrees (the outer ring splits a 90 degree quadrant into three 30 degree sectors, and the tail feather pair cover half of one such sector) which I admit is probably within my sailing tolerance for wind direction. But lw395 says he wants 1 degree...

Away mon!! You can eyeball the pointer to 5 degrees or better and is 1 degree really needed
