Anemometer replacement recommendations wanted

Postby Tmack » Sat Oct 26, 2019 9:11 am

Hi group,

Does anyone have recommendations for a replacement anemometer? Mine is missing cups and the unit is not connected to anything down below. My F32 is parked in the yard with the mast out. Perfect time to work on this. I am hoping to pull the data from a new unit into a boat monitoring system (homemade or commercial). I appreciate any input.

Thanks. Tom

All I can say is anemometer's are equipped with stealth AI. When the anemometer knows you want good wind numbers it will stop working. It will start again when You no longer need the wind speed/direction. I have a Raymarine unit which is so equipped.

I have often wondered how those ultrasonic wind sensors work out.

Two summers ago I switched to a Garmin GNX 20/21 set of gauges for my F32. I am very pleased with them and being wireless from the anemometer to the head installation is very easy to install. Occasionally, as Mike Cunningham pointed out, I have had interruptions in readings, I'd say maybe 5 in the 2 summers of using them. The interruption lasted maybe 5 seconds if that, other than that they have been rock solid and the price was better than other manufacturers that I researched. Good luck in your search.

Good Post Mike :D I hear you.. All I can venture to add is with the movement in a seaway - what with the mast bounce and creak, etc., to explore that little junction box by the mast base - install a new one and add plenty of dialectic grease after super securing all connections. I've found that is a point of origin for plenty of gremlins :D

for what its worth only :)

Thanks for the feedback guys! Look out for stealth AI and good advice on the gremlins. John I really like the idea of wireless anemometer data. The Garmin GNX looks pretty slick, I will be doing a lot of comparisons of units.

However, I'm also exploring open-source, low-power computer systems for data collection (as I have more programming skills than $).

How do the wireless instruments get power?

TackTick wireless unites - now owned by Raymarine state “Raymarine Wireless displays are solar powered with integrated lithium batteries that power the unit for life. Power consumption is so efficient that units can run autonomously for up to 300 hours“

I would like to hear how people like or not like these instruments...

Hi Geoff, as Camino states there is a solar cell integrated into the masthead unit along with a lithium battery. I have yet to see any issues whatsoever with the charging, or the rest of the instrument system for that matter. Just be aware that there is recommended limit of mast height to head unit. This particular model may not work very well with masts a lot taller than the F32's depending on mounting of the head. With the issues I have experienced with other manufacture's devices, one in particular, I started choosing other alternatives when available. I find pricing is usually better as well as overall functionality.
