Training agency
Unified Team Diving
A recreational, technical and cave training agency whose cave track runs from a non-certifying Overhead Protocols class through Cave 1, Cave 2, Cave Stage, Cave 3, CCR Cave and Cave Gold.
UTD Scuba Diving, LLC trades as Unified Team Diving and offers recreational, technical, cave and rebreather training [1]. Its own explainer sets out a cave track that begins only after its Essentials of Tech course [2].
UTD's first overhead class, Overhead Protocols (OHP), is described as comparable to an intro to cave course but is not a cave certification. Cave 1 is restricted to the main line and simple navigation and, unusually, expires 24 months after issue; UTD says it is the only UTD scuba certification with an expiry date. Cave 2 is UTD's full cave level within no-decompression limits; Cave Stage, Cave 3 (decompression), CCR Cave and Cave Gold follow [2]. UTD covers caves and mines in one curriculum rather than issuing separate mine cards [2].
