Tribrachs are handy when you need to add the ability to use an optical or laser plummet, instead of a plumb bob. Using a plumb bob can use valuable time, and can be difficult to use in the wind. Also, Tribrachs can help with leveling some surveying instruments and also used when swapping out instruments while wanting to keep the same set up location.
