This is the newest model, the WMM Edition based on the state-of-the-art World Magnetic Model (WMM) for precise wind direction worldwide. Announcement and new features here. If your boat has already been launched, you can even raise it on a halyard without lowering or climbing the mast, until you can get at the masthead.

The home page has a short product summary and there is a list of features and innovations. The Wind Instrument RB™ was launched at the Miami Boat Show with an overview in the Strictly Sail boat show guide. See below for SailTimer reviews. The ingenious design of the battery nose cone is also illustrated in this YouTube overview.

We deliver to all countries and have very good FedEx rates because of our volumes. The shipping cost for your country will be shown once you enter your address. Ships from Canada. If you have any questions about duty or taxes for your country, please email. We always try to ship with FedEx for speed. But airmail may occasionally be used if FedEx has unexpected costs to your location or if you use a post box for your delivery address. Apologies for the higher delivery prices since spring 2022, presumably because the carriers are encountering higher fuel prices due to global events.

Note that this new model of Wind Instrument RB WMM is not compatable with previous generations of Air Link (1, 2 or 3). But there is a new lower-cost version of the Air Link in development. It will be announced in the SailTimer newsletter when available perhaps in fall 2022, and on the Air Link order page.

    Eduardo, Thanks for your comments! Don’t worry; the Wind Instrument comes with a lifetime warranty against damage from sea birds. This is noted on the order and warranty pages and was announced in the SailTimer newsletter a few years ago (

    My initial thoughts of this device is that it’s almost too good to be true. It works fantastically yet it’s ridiculously cheap. Given that I have a rotating mast, my only other option for accurate wind data at the cockpit was to drop $2k on one of the other brands with a mast rotation sensor. This one does the same thing for 1/4 the price. The jury is still out on durability since I just got it, but time will tell. It does seem somewhat delicate but as long as I don’t sail in a hurricane and a bird doesn’t land on it, it should be fine. Super happy with the apps as well. I use mine with an old iPhone 6 Plus in a waterproof case as my dedicated chart plotter and wind data display (NMEA Sail and MID WiFi apps are awesome for this although I wish these were integrated into the SailTimer Charts app for IOS) and I’m able to replicate a $3500 system for $500. Not bad at all. Once the new Air Link is released I should be able to do even more. Bargains in the boating world are practically unicorns. This is one of the few. Great product!

    Recently received my SailTimer. It was packaged beautifully, and shipped promptly. Can’t wait to try it when my boat goes in the water next month.

    I would rather hear from other sailors because I’m not happy yet. Hoping that the iPhone app eventually comes around.

    Mast unit works well. PAY ATTENTION to guidance on keeping battery charged. IOS apps work best. Originally bought the older AirLink unit to facilitate Android connectivity. In January I bought the revision 3 AirLink unit with expedited setup. Works great!

    I have the Sailtimer unit. I had some issue with the software working. I had immediate response from Sailtimer support and all was resolved quickly. Great Job assisting me.

    Used this instrument on a Rhodes19 this summer. I like how it performed and would recommend this device. Had one issue when removed at the end of the season. Somehow water got into the nose cone and damaged the connector on the instrument and battery. Sailtimer has agreed to send replacement parts. I will install using a dab of dielectric grease on the connector next season to help eliminate this problem in the future.

    “I’ve had an excellent experience with SailTimer. The product arrived in a timely manner. They respond to questions very quickly and with clear information. In testing the SailTimer in my home I damaged the battery plug. SailTimer has graciously allowed me to return the product in spite of the damaged plug as long as I pay for the replacement battery. They have been more than fair in all of their dealings with me.”

    Looking forward to using it more with different apps. Seeing wind with Navionics charts in the SailTimer app is great.
