I appear to be the odd one out here, I only have the one tripod a Benbo Clasic No 2 and I've been using one for over 20 years now, it offers great flexibility in terms of use.
Due to the unique way the legs and column lock, i.e. one bent bolt, which is where I believe is where the name comes from BENt BOlt. Originally based on a early machine gun tripod mounting from WW1.
The larger diameter part of the leg is at the bottom and slides over the upper part. This means the leg is effectively sealed up to the first clamp, on mine that's 0.84m (33") measured from the tip to the clamp, so you can stick it in sand, mud water, whatever you want without problems.
It takes a little getting use to, but the trick is not to loosen it too much, otherwise the legs go every which way. The double ended centre column offers a choice of standard 3/8" or 1/4" fixing.
It extends up to 2.56m (101") and closes down to 1.14m (45"), weight 3.75kg (8.27 lbs) all measurements are not including any head.
