Tacktick mn30 Wireless Wind Instrument - Wind transmtter details

[jono63812]

We have a Tacktick mn30 wireless wind instrument, from what I can see Tacktick are now part of raymarine? a while ago I cleverly took the wireless wind transmitter off the mast to replace the rechargeable battery and dropped the transmitter into the sea, sinking to 40 fathoms!!! I'm an idiot. I would like to get a replacement wireless wind transmitter for the top of the mast, does anyone you know the serial number or spec of what I might need? I have looked online but just don't want to get an incorrect one with a different frequency etc which won't be compatible with my Tacktick mn30 instrument.

Thanks for your help.
