I'm curious if anyone out there has used the (relatively) new Hydrascope extendable crane from Chapman. I haven't yet, although I have gone by Chapman and looked at it. If it works as well as it looks, it has to be one sweet arm and should give the Technocrane some serious competition. One interesting note: the guys at Chapman told me that they submerged one in a swimming pool for several hours, moving it underwater and it worked like a champ. Anyone used one? David? Anyone?
