I would query the buzzers.
The indicator/float will have to be the size of a buoy to see it in the waves
Its very rarely calm enough to fish them static from a boat.
The places up there are wind tunnels with Glencorse and the Rigg being the worst.If its more than 15mph on met check in Edinburgh its usually a white knuckle ride up there.If it is calm enough the dries are the way to go.
when/If Glencorse reopens it has a great head of wild browns. As per your previous question about wandering up an having a cast.....You would be technically trespassing on a public water supply.The waterboard keeper lives in the cottage at the dam wall and his two big dugs are always hungry

and the farmer at the top end has a pack of nutters masquerading as sheepdugs.
Word is out that somebody is going to take it on if the "board" splits it from Clubbiedean (The poachers paradise up from Bonaly).
