Where is what maroon tower where is it in the book find me where the maroon head is at

Maroon head and lower joints rely on the top wire fixed, the use of a period of time will occur after the top wire damage, so that the maroon head joints can be rotated at will, resulting in gyro-skewing instrument installation, downhole and up and out of the process, it often happens that the connection part of the cable core broken, so that the instrument disconnected, had to be the instrument from the well up to reconnect.

The tap is an improved cable for geophysical logging operations, and the instrument is conveniently connected to the tap, because the main components of the shell are not fixed connections with each other, and all the perishable, sealing and other related components are assembled on the base.
