{"product_id":"davis-instruments-air-flow-tels-sail-wind-indicators-set-of-14","title":"Davis Instruments Air-Flow Tels Sail Wind Indicators, Set of 14","description":"\u003cp\u003eThe Davis Instruments Air-Flow Tels are lightweight, ripstop nylon telltales that attach directly to a sailboat's sails to show airflow across the sail surface in real time. Seeing how air moves across the sail lets a sailor trim for maximum performance, adjusting sheets and sail shape until the telltales stream smoothly rather than fluttering or stalling. Each kit includes 14 individual Tels along with full instructions covering where on the sail to apply them and how to read their movement once underway.\u003c\/p\u003e\u003cp\u003eInstallation requires no holes or sewing: each Tel attaches using a waterproof adhesive locator disc, so it can be applied cleanly to the sail cloth and will hold up to on-water conditions. The Tels are made from a lightweight ripstop nylon material, chosen so they respond readily to light air movement without adding drag or weight to the sail. This makes the Davis Instruments Air-Flow Tels a straightforward, low-cost way for sailors to visualize and improve sail trim on any sailboat.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Davis Instruments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 950\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Air-Flow Tels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Sail Wind Indicator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Wind Indicators\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Nylon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e As Shown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Tels Included:\u003c\/strong\u003e 14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Method:\u003c\/strong\u003e Waterproof adhesive locator discs, no holes required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 8 x 4 x 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Full instructions for placement and reading\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat are the Davis Instruments Air-Flow Tels used for?\u003c\/strong\u003e They are telltales that attach to a sailboat's sails to show how air is flowing across the sail surface, helping a sailor trim the sails for maximum performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many Tels come in the Davis Instruments kit (part number 950)?\u003c\/strong\u003e The kit includes 14 individual Air-Flow Tels, along with full instructions on where to apply them and how to read them.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need to drill or sew holes in my sails to install these?\u003c\/strong\u003e No. The Davis Instruments Air-Flow Tels attach using waterproof adhesive locator discs, so no holes or sewing are required.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material are the Air-Flow Tels made from?\u003c\/strong\u003e They are made from lightweight, ripstop nylon, which responds readily to airflow without adding drag or weight to the sail.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow are the Air-Flow Tels attached to the sail?\u003c\/strong\u003e Each Tel is applied to the sail cloth using a waterproof adhesive locator disc included in the Davis Instruments 950 kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size are the Air-Flow Tels?\u003c\/strong\u003e The Davis Instruments Air-Flow Tels kit measures 8 x 4 x 2 inches as packaged.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Air-Flow Tels kit weigh?\u003c\/strong\u003e The Davis Instruments Air-Flow Tels (part number 950) weighs 0.04 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre instructions included for placing and reading the Tels?\u003c\/strong\u003e Yes, the kit includes full instructions covering where on the sails to apply the Tels and how to read their movement while sailing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill these Air-Flow Tels work on any sailboat?\u003c\/strong\u003e The Davis Instruments Air-Flow Tels are designed to attach to sail cloth in general and are not restricted to a specific boat make or model.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre the adhesive locator discs waterproof?\u003c\/strong\u003e Yes, the Air-Flow Tels use waterproof adhesive locator discs designed to hold up in on-water sailing conditions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color are the Davis Instruments Air-Flow Tels?\u003c\/strong\u003e The Air-Flow Tels are supplied as shown in the product listing for part number 950.\u003c\/p\u003e","brand":"Davis Instruments","offers":[{"title":"Default Title","offer_id":49026458845403,"sku":"DAV-950","price":17.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/00950_02_7da807f1-8780-4d89-bbef-5ee0f1148ba7.jpg?v=1785026825","url":"https:\/\/www.goodvibesmarina.com\/products\/davis-instruments-air-flow-tels-sail-wind-indicators-set-of-14","provider":"Good Vibes Marina","version":"1.0","type":"link"}
