What is different between a Astrolabe , Clinometers , Sextant, Bubble Sextant and Transit/Theodolite. 1) Astrolabe , Clinometers is basically a plumb and a protractor apx ?° some are deviations ?° and you slip to ?° [15 minutes] readings. This the lowest cost a protractor from dollar store and strar with string and old rusty nut for plumb bob Other low cost Clinometer More common type use primary on trees The is call a Clinometer but also could be a Astrolabe or Sextant Low accrucy High end Clinometers with range finder 2) Sextant measures angles between two objects typically the horizon and Sun or Stars 6 minutes to 20 seconds Use veneer or a worm gear. Very costly use on Large Ships Small size for lifeboats and practise 3) Bubble Sextant Use a bubble level because the horizon is not a option 6 minutes to 20 seconds. Use veneer or a worm gear. 4) Transit/Theodolite use a bubble level but can measure the angle between two objects 30 seconds for Transit and Theodolite is 20 seconds to 5 seconds only uses a veneer for greater accuracy , except for electronic type. This is a Transit and also call a Theodolite A Theodolite has to be accurate to 20 minutes and the telescope rotat 360° This photo shows the 360 has all spec for a Theodolite too. This the one use for testing machine tool accrucy like rotary tables and deciding heads. This sitting on my work bench last month.
