Evaluation of Sensus Data Logger for Use in Operational Dive Data Collection
Abstract
Naval Sea Systems Command (NAVSEA) tasked the Navy Experimental Diving Unit (NEDU) to identify and evaluate candidate devices that divers can carry to electronically record their depth!time profiles and that can be suitable for collecting operational dive data. One such candidate device, called a data logger (DL) to signify its purpose in logging dive data, is the Sensus (ReefNet Inc.; Mississauga, Ontario). With emphasis on its depth accuracy, NEDU tested the Sensus for use in collecting operational dive data. Thirty DLs were dived twice to a depth of 200 feet of seawater (fsw), with stops at decades of depth on both descent and ascent. Analysis of the results show that all Sensus depth readings appeared to be within the i2 fsw depth accuracy desired. The depth readings were also highly reproducible across all DLs and could be corrected to an accuracy of about +i fsw, the accuracy of the test chamber system. The Sensus data logger appears suitable for collecting operational dive data on dives in a approximately 200 ftw or shallower.
