Telemetry sub

It communicates with surface system by ADSL mode. The effective speed is equal to or higher than 800Kbp/s. It can communicate with other 580-series tools by Ethernet under transmitting speed of10M. It can measure natural gamma ray as well.

Gamma ray sub

This sub measures the total amount of natural gamma ray in formation. 

Telemetry sub

It is composed of cartridge and housing which is made of PH stainless steel.
