There is much confusion on the technologies that make up the CTX. There is also confusion on how to best use the CTX to get the best results. This is understandable as it’s a very complicated detector to master, especially for the beginner. Even once you come to an understanding of using the CTX, some of its functions and its many screens may be time consuming. While there is a user manual, there is a lot left wanting. Highly recommended across the board is the “Minelab CTX 3030 Metal Detector Handbook” book by Andy Sabisch that can be purchased online. Almost 200 pages long, it will provide in-depth detail about unlocking its many features and full potential.
