The Clear Range Indicator was a British torpedo-control instrument developed in a series of Marks.
Two designs were discussed in the Annual Report of the Torpedo School, 1916[3]
These were supplied to "all modern ships" by the end of 1917. One was apparently fitted to the holding down ring of the Torpedo Deflection Sight Mark II, and a third type was added to the spindle of the T.D.S. Mark III, an arrangement that was found to be more compact and convenient.[4] Even the Spartan T.D.S. Mark VI had one.
Mark I
This original model was for use in conning towers.[5]
Mark II
This model was for use with Torpedo Deflection Sight Mark II.[6]
Mark III
This model was for use with Torpedo Deflection Sight Mark III and could also help determine how much of a course alteration would be required to bring the sights on.[7]
Mark IV
This was a new model was for use in conning towers with restricted arcs. It could serve the functions of the previous Marks but also:[8]
- show "the arcs between which torpedoes can be fired in connection with the restricted arcs of 70 degrees to 110 degrees."
- the gyro bearings corresponding to those limits
[TO BE CONTINUED - TONE] It is described[9] and its use outlined[10] in the Annual Report of the Torpedo School, 1918.
