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.

    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!

    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.
