So I received this tripod the other day through a 20% off drive at one of Sweden's best known camera stores, so I got it at very nice price even if it's still not exactly a cheap tripod. I just did a quick test today to check it out, so this is not a review, just a few thoughts.
This tripod is extremely sturdy. It's made of 8 layer 100% pure carbon fibre and magnesium alloy. It is the biggest tripod that 3LT have in their current line-up of awesomeness. It's also the third 3LT tripod I have in my possession now. It's not a travel tripod, since it's too big and heavy, though it's still not heavy and ways in at 1.75kg without the head. The head that comes with it is the Airhed 360 which weighs 408g and the combination seems extremely sturdy. The tripod and the head both have a maximum load capacity of 40kg, which is quite a lot. I also added the Equinox Switch Clamp which is a quick release clamp instead of the "screw in and tighten" clamp that is original (which is a 360 pano clamp on this one, but I don't shoot panoramas anyways) and it works very smoothly and clamps on with a very firm grip on my RSS L-plate (all 3LT heads and clamps are Arca Swiss compatible).
The locking system is second to none and since the tubes on this tripod are pretty fat, the locks are big, chunky and awesome to use (made of rubberised magnesium alloy). And while the locks are good on my 3LT Brian, these are even better.
And like all other 3LT tripods, one leg is removable and can be used as a monopod.
At the bottom of the center column, there is an attachment ring to hang some type of ballast from, to weigh the tripod down even more during extremely windy conditions. The tripod comes in a nice carrying bag (with shoulder strap) made of military grade canvas, which can be used as a ballast as well. It also comes with a multi tool/carabiner/bottle opener.
So yes, this is not the smallest or lightest tripod, but compared to my old Manfrotto 055 Nat3 tripod it's not even half its weight. And even though my 3LT Brian is awesome and sturdy for nearly everything, when it comes to several minute long exposures at the beach, something even sturdier is needed since even the slightest movement will end in a blurry photo, that's why I got this tripod, even if it won't come with me when I travel abroad.
