Water typically does not present a uniform acoustic transmission medium because the velocity of sound propagation and other sign transmission characteristics differ with water temperature, salinity, and depth (or stress) every of which may fluctuate with dive location. Therefore, the transmission time between a transmitting unit and a receiving unit differ with the situation of a dive (i.e., based mostly on the water chemical make-up) and iTagPro Device sometimes even with a planned depth for a dive. Such gadgets, systems, and strategies preferably could be adapted to be used in various dive locations and below different water circumstances and would be readily adapted for use with multiple divers and dive teams of various expertise and expertise. 5 toes for unskilled divers or for iTagPro Device harmful circumstances while a fifty-foot, hundred-foot, two hundred-foot, and sometimes greater security vary could also be set for skilled divers or comparatively safe diving situations. An alert will be robotically or manually transmitted to and from the dive grasp when the space is exceeded.

An alarm is activated when the distance condition is met by the found distance or when activated by a person. The space is then discovered from the measured time. FIG. 1 is a block diagram generally illustrating the system of the present invention. FIG. 2 is a movement chart typically illustrating the method of the current invention. FIG. 3 is a block diagram illustrating in more detail one embodiment of the means for discovering distance in FIG. 1 . FIG. 4 is a move chart illustrating in additional detail the step of discovering distance in FIG. 2 . FIG. 5 is a block diagram illustrating in additional element one embodiment of the means for discovering distance in FIG. 1 . FIG. 6 is a stream chart illustrating in more element the step of discovering distance in FIG. 2 . FIG. 7 is a block diagram illustrating in more detail one embodiment of the means for discovering distance in FIG. 1 .

FIG. Eight is a stream chart illustrating in more element the step of discovering distance in FIG. 2 . FIG. 9 is a front view of a diver communication gadget of the present invention illustrating a display surface showing dive time, current separation distance settings, present message from dive partner or dive master, and communication frequency along with different features of the diver communication system. FIG. 10 is a side view of the exterior of the diver communication machine of FIG. 9 illustrating the battery compartment. FIG. 12 is one other purposeful block drawing similar to FIGS. 11A and iTagPro Item Finder 11B illustrating the use of a dive master communication iTagPro Device for concurrently monitoring divers in two separately communicating dive teams which might be diving using completely different safety distances. FIG. Thirteen is a entrance view of a dive grasp communication gadget or master controller illustrating options similar to the diver communication machine of FIG. 9 and likewise illustrating features facilitating monitoring and speaking with a number of diver and dive teams.

Additionally, the diver communication system and method is helpful for permitting a number of dive teams diving inside a single dive space to speak with each other with out inflicting communication issues.
