Tacktick mn30/T033, economy wireless
I've had impressive results with the Tacktick Micronet system on the Annie G., but the gear is expensive. Good then that Tacktick has introduced an economy version of the T101 wind system, called the mn30 and/or T033 (click on photo above for larger version). The nifty solar-powered, wireless masthead sensor is the same, but the display is powered from a boat's 12v supply instead of solar cells. Which seems like a reasonable trade for a discount of over $400 retail, and might even be preferable on boats where the display doesn't get sufficient sunlight. Actually, there may be some other features missing from the mn30/T033 that I haven't found yet. But I do know that it supports basic calibration like offset and speed %, and can integrate with a Micronet wireless speedo or NMEA box (& GPS) for True Wind readings. Here's the manual PDF and U.S. distributor Ocean Equipment's listing.
Why the two-moustache display? The manual calls them the head and tail wind angle pointers. Does the tail pointer have any useful value?
Are sailors really happy with this wind angle display? I wouldn't be. It doesn't replace a Windex.
The manual also says it operates on either 868 MHz or 916 MHz.
