[[File:DreyerTableMarkIII_elevationAndPlan_June1912.jpg|thumb|512px|'''Mark III Table plan from June 1912'''<br>Note bearing plot on left with single deflection drum and primitive rate grid.]] The '''Early Dreyer Bearing Plots''' is a collective description of a family of bearing plots found on [[Dreyer Fire Control Table|Dreyer tables]] before the advent of the [[Standard Bearing Plot]] and [[Gyro Director Training Gear]]. These bearing plot patterns changed incrementally and are historically important, for it was ones of this lineage that found general use at [[Battle of Jutland|Jutland]]. ==Improvements== Proposals were issued from {{UK-QueenElizabeth|f=p}} in December, 1915 suggesting that increasing the slope of the bearing line might assist in discerning the low bearing rates that would prevail in most long-range fighting. When a "Mark V" table was erected in {{UK-Ramillies}} in July, 1917, the transmission steps of the bearing were also reduced from 1/4 degree steps to four arc minute steps by use of a special transmitter made by Elliott Brothers. This alteration greatly improved the visual fidelity of the data. It was ordered that these improved bearing transmitters should be provided to other ships, but the same fine transmissions were part of the [[Gyro Director Training Gear]], and so this work was put off in favour of that innovation.{{UKTH23|p. 27}} {{TBCTONE}} <!-- TODO: add in images and descriptions from Original table TODO: add in descriptions from Mark III table TODO: add in images and descriptions from Royal Oak's handbook. --> ==See Also== {{refbegin}} *[[Standard Bearing Plot]] *[[Gyro Director Training Gear]] *[[Dreyer Fire Control Table]] {{refend}} ==Footnotes== {{reflist}} ==Bibliography== {{refbegin}} *{{BrooksDGBJ}} *{{DreyerH}} *{{THArgoAndDreyer}} *{{UKDreyerMarkIV}} {{refend}} [[Category:Dreyer Table Components]] [[Category:Fire Control]] [[Category:Shipboard Equipment]]
