Blimey what a question :

We have just lifted horizontal fishing poles poles to vertical and improved them for our use. They are in their infancy and will be developed further.
I have used and sold on a basic fishing pole at 80ft and see no reason why the same pole cannot be used at 100ft if you know how.
120ft has according to Luke's friend already been achieved but the pole broke.
So to answer yes, why not. Asking me how to do it is however a question I am not prepared to answer because basically its untried. Give me the money and I may be able to give you the answer you want.
