Ive got the telescopic version myself, yes weighs about 10kg Id say if that, but veeeery useful, cleaning panels, doing jobs, helping others etc, the small storage and ease of use outs the weight perspective down the list for me.Not sure if what I am picturing is a surveyors ladder but in the past I have seen small section ladders that had narrow steps. The ones I am thinking of had your feet almost together. If that is a surveyors ladder it wouldn’t have done me without hopping up as I can’t get my feet very close together. I have committed now anyway but it’s giving strong winds and rain until at least going dark so when they arrive they will have to wait until tomorrow. I will report back on their usefulness once used
