Davis Instruments Air-Flow Tels

Works well. Easy to apply.

Brand name product. A bit overpriced for what it is. As an avid sailor I use these telltales to help adjust the forsail(s) for best performance. They generally last for 3 to 4 seasons before coming off or shredding so this package will last fir some time assuming that the adhesive doesn’t deteriorate over time.

The telltales are just what you need, and they fit into slits in an adhesive disc in a way that is simple, clever, and secure. The only problem is that the "slippery" backing card that holds the discs is not slippery enough, or it delaminates too easily. With several of the discs the first layer of the backing came off and could not be removed. Fortunately there were way more discs than I needed (I think there were 12), so I was not inconvenienced.

They work well. Make sure you stick it where you want it the first time, repositioning is not a good idea. I installed them on my mainsail and furling genoa jib. I basically guessed as to where the best positions are to mount them. It would be nice to have some suggestions on placement. As an intermediate level sailor, it would be nice to have a bit less guesswork involved. They are easy to install, and seem to stick very well. (I did clean the sail surface before sticking them on, something that I would highly recommend.)

Davis has produced many common sensical items for the sailor and this is one of them. The tells are generously long for either jib or mainsail and the round stick discs are good sized and do their job. If your sail isnt clean suggest your used a soft rag and some alcohol to clean prior to attachment....

Good product. Been around for years. Easy to install and use. Make sure you clean the sail first and make sure you put it where you want it. Getting it off of a clean sail is a job.

Es lo que esperaba

Placed on main and jib, both sides. Easily shows the flow of air across the sails. Also placed on the standing rigging to indicate the direction on the wind. Simple but effective on all fronts.

Che dire a parte che costano uno sproposito per essere solamente delle striscette di stoffa, ma mi servivano e quindi le ho comperate. L'adesivo fornito è scadente, le ho fissate alla vela con un punto di filo cerato.

excelente

C'est bien ce que je voulais

Très bon
