How deep can a CTX 3030 go?

Could you elaborate on the capabilities of the CTX 3030 in terms of its depth capabilities? Specifically, I'm interested in understanding how deep it can effectively operate, whether it's suitable for shallow water exploration or if it can handle deeper dives. Additionally, is there any limitation or considerations that one should be aware of regarding its depth performance? Understanding these details would help me determine if the CTX 3030 is suitable for the type of underwater search I'm planning.
