How often have you been bending down re-adjusting each leg on your tripod until everything is level?If like me, just too often and it wastes so much time, over recent years I have started using tripods with build in half-balls which overcome this problem, but what if you already have a good tripod that you want to make the most of?Well this is where the Innorel LB60mm comes in to its own, you just fit it between the tripod top plate and your pan & tilt head, it only takes a moment to level up and you are ready to go, no more re-adjusting each leg on your tripod, and not only is it a lot faster but you can set your tripod to the maximum height.In use I have found this leveller to be fast in operation due to having just one knob and it is very sturdy and feels like it could handle more than the suggested weight limit.My personnel set up method is to use the cameras own build in on screen leveller as this is easier to see and perhaps a bit more precise as well.Another like is the use of either 3/8" or 1/4" mounting, a 10Kilo weight limit and even it's own compact bag which is good to avoid scratching other gear in your overflowing camera bags.Is the Leveller worth the money, well how much would it cost you to buy a new tripod with a half-ball build in, I rest my case. It converts any tripod.
