Unless I've missed it nobody has talked about distance. By this, I mean how far out are folk fishing from the rod top that they cannot see a float top?
I agree totally the leaves are a problem, but surely if they are that bad then fishing at any distance (ie casting over a leaf strewn swim) is a bigger problem in the first place, let alone see a float top once the thing has settled in the water !!
I don't say it's easy to find the best method in autumn conditions, but perhaps some are trying to fish too far out AND spot a silly orange tip sitting 10mm above the surface.....
Greenie suggests having a look at driftbeaters; Good call IMHO (you have to start somewhere!) and although the sight bob on the tip must help, I suggest this float doesn't necessarily need to be shotted down to a dot - the very thin stem, IMHO, still keeps the thing sensitive and if painted black, and fished no more than a metre or so from the rod tip, with 10/15mm of stem showing it can work okay....
And before anyone suggest otherwise I have used this float in such a manner and it can work very well, although for the ' 2mm max float showing above the surface' type it may suggest 'just not sensitive enough' sort of opinion.....
Yes, I agree that fishing in this manner limits your scope in that you cannot fish at distance, but I have seen, countless times, the ability of folk to ignore 'close in' fishing and instead cast to the horizon and over the top of fish in front of them !!!
Let me give you another scenario around sensitivity; In the 'old days' when enormous bodied floats 12/14" long, such as Zoomers et al where in vogue and where casts great distances were made by matchmen, the amount of float left above the water needed to be sufficient just to see the damn thing and yet it was still a sensitive float simply because of the shotting arrangement, and not because of the amount of float showing. I know 100% that I caught fish in this manner and a 6" roach took the float under without a problem even with 2" of float showing !
No, not ideal, but it worked - because, as I say, the shotting was spot on !!!
All I'm suggesting is fish a little closer in, have more tip showing, experiment with colours and as Mr Vimes suggests, try different glasses/lens....
It's a case of working with what you've got and using a bit of common, rather than sticking a float four rod lengths out and then crying foul !!
Good luck though, and please ignore the above if you know better !!
ps On the sensitivity thing; Didn't I read an account years ago by that master of the float Ivan Marks, who, when faced with bream at some distance actually taped TWO very long floats together to give an 18" beauty (or was it longer?) just so it would carry enough shot to reach the fish ! From memory it worked a treat and caught the fish simply because the shotting was dead right !
I will go to my grave believing the shotting is just as important as the amount of float above the surface - in fact, IMHO more so !!
Others will surely disagree......................and why not!!
ps Sorry to prattle on; Just for the record I still love to use a home made onion type float comprising a cane stem with a balsa ball at the top that is shotted down so just the 'dome' of the balsa is showing (almost flush with the surface) and this is massively sensitive. Just a touch and the float is gone !
Difference is, I don't use it at autumn time !!!
