Ever on the lookout for climbing gear, I ran across these guys at a Hamfest in Richmond, VA:
http://www.ezhang.com/
They make a wrist-braced slingshot with a fishing reel attached. Hams use it for setting antennas.
It's a bit pricey, but well constructed and very comfortable to use. On their website, there's a calendar of Hamfests they'll be visiting. If you catch them at one, they'll probably give you the "show special price".

Yeah but the ad says "no climbing trees" where is the fun in that. Just kidding. I know of some climbers that have been experimenting with this or one like it. I have not as I am still doing it the good old fashioned way and I haven't had the need to get that first pitch higher than I can throw. But you never know what tomorrow will bring.

I hope you don't mind my kidding with you! Have a great weekend.

i'm spectical if the fishing reel is really necessary, if not you could just get a black widow catapault for £10 and do just the same job

Steve,

Can you convert your £10 into the universal conversion rate: how many beers does that buy?
