Davis InstrumentsDavis Instruments 3150 WindTrak 15 Suspension Bearring Wind Indicator

Replaced broken unit on my mast. The Windex is well made and highly functional. I like the spike which keeps osprey from landing one breaking the Windex. Small bites still use it for their entertainment, spinning around and around. Product is well packaged and easy to install while hanging off the top of your mast.

At least there's no reason to do it more than once.

Great product , easy to install and ready for a new season

When I bought my sailboat the guy said my windex was worth a $100. a year later when I went to my boat slip and saw my windex bent and broken to pieces like a Gargoyle tried eating it. I found out that large birds of sorts like to rest on them. That's when I decided to buy this Windex. When it arrived I found it to be much larger and robust than my other and.. half the price I feared it would be. Anyway, this has not been used yet but I did fasten the base to my mast head while the mast is down and boat on trailer. I found I was lucky as this base is different than my other...my other has a two screw type base which I still had but this guy is much thicker and robust and would not fit into it. I was thinking CRAP! but found I did have a single hole dead center under where the other base was and this base/bolt fit in perfectly. I like how this base can stay on the mast head and with one screw you can remove/install this windex. I'm a happy camper and may revise this review with another star when I give it a test run.

You want accurate wind direction? This works. Very sensitive. High quality. I mounted it on my garage peak to see the wind direction from kitchen window. Very happy with it. Buy.

While I feel the wind in the tiller response and general boat performance, other helmsmen guests can better steer the boat with this item at the top of the mast. It is very easy for me to explain that the tail must stay outside the "V". There is no reason these need to be made with such thin plastic though. I've had two of these broken-- one by the boat yard that worked on my boat claiming "it was already broken" and another by age and a bird sitting on it.

This is a great wind indicator. A bird decided to retire my old one (looking forward to having the spike on top now!), and I've enjoyed this new one very much. It took only a couple minutes to assemble then it installed very easily on the mast of my sailboat. I was very pleasantly surprised to find a diagram on the back of the box that showed different angles based on how your boat performs in the wind. This is the best wind indicator I've found and if I ever need a new one, I'll definitely buy this one again.
