Thanks John, It just takes a leap of faith to try modular. Most use the Zensor first 2 sections together, and carry another two combined in the same hand, they also put them on the roof rack like that.
If you employ staff or by yourself then you need to give them the best choice available. As you said its two poles for less than £70 and no other middle man, its as common as muck and cannot be taken advantage of by any supplier. I have high hopes of drastically cutting the costs of c/f high poles. 3 types being delivered tomorrow.
Its just a brush on a stick. Its the technology thats made it happen though.
