Water typically does not present a uniform acoustic transmission medium as the velocity of sound propagation and other sign transmission traits fluctuate with water temperature, iTagPro shop salinity, and depth (or pressure) each of which can range with dive location. Therefore, the transmission time between a transmitting unit and a receiving unit vary with the location of a dive (i.e., based on the water chemical make-up) and typically even with a planned depth for a dive. Such gadgets, techniques, and methods ideally could be adapted to be used in varying dive areas and under completely different water circumstances and would be readily adapted for use with multiple divers and dive groups of varying skills and experience. 5 ft for unskilled divers or for harmful situations while a fifty-foot, hundred-foot, two hundred-foot, and sometimes higher security vary may be set for skilled divers or relatively safe diving circumstances. An alert could 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 consumer. The gap is then found from the measured time. FIG. 1 is a block diagram typically illustrating the system of the current invention. FIG. 2 is a circulation chart generally illustrating the tactic 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 circulate chart illustrating in additional element 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 movement chart illustrating in more detail the step of discovering distance in FIG. 2 . FIG. 7 is a block diagram illustrating in more detail one embodiment of the means for iTagPro shop discovering distance in FIG. 1 .

FIG. 8 is a circulate chart illustrating in additional element the step of discovering distance in FIG. 2 . FIG. 9 is a entrance view of a diver communication device of the present invention illustrating a display floor exhibiting dive time, present separation distance settings, present message from dive accomplice or dive master, and communication frequency along with different options of the diver communication system. FIG. 10 is a facet view of the exterior of the diver communication machine of FIG. 9 illustrating the battery compartment. FIG. 12 is another useful block drawing just like FIGS. 11A and best bluetooth tracker 11B illustrating the use of a dive grasp communication machine for concurrently monitoring divers in two separately speaking dive teams which are diving using different safety distances. FIG. 13 is a entrance view of a dive grasp communication device or iTagPro reviews master controller illustrating features much like the diver communication device of FIG. 9 and likewise illustrating options facilitating monitoring and communicating with multiple diver and dive groups.

Additionally, the diver communication system and iTagPro bluetooth tracker method is helpful for permitting multiple dive groups diving inside a single dive space to communicate with each other without causing communication problems. This discussion contains a proof of using preset separation distances and the automatic transmission of alert signals when the decided distance between two units exceeds the preset separation distance for the two gadgets. An necessary aspect of the invention is the combining of multiple capabilities in a single diver communication system and how the unique mixture of those features facilitates effective communication between diving companions and, considerably, between 3 or extra divers inside a dive group (even when diving in proximity to different dive groups) and between a dive grasp and divers in multiple dive teams. FIG. 1 illustrates a system 2 for alerting when a primary machine 4 and a second device 6 are separated by a preset distance. System 2 consists of a means 8 for discovering a distance 10 between first system 4 and a second system 6 , iTagPro shop a comparator 12 , and an alarm 14 .

System 2 can also embody numerous additions resembling a person enter interface 16 and a storage device 18 for storing a preset distance situation 20 or executable instructions. First system four and second machine 6 may be of any form or iTagPro portable design. System 2 might have a variety of uses with each use having its personal desired form. 2 and second machine 6 are conveniently embodied in a shape to be worn on a diver's wrist or attached to the divers Buoyancy Control Device (BCD). Additionally, when utilized by divers, it could also be fascinating for first gadget four and second device 6 to incorporate typical diving options resembling a dive time indicator ItagPro or different indicators useful for divers. Four and second machine 6 are being described as separate units. 4 and second system 6 every embody all the elements of the other system. In that embodiment, every of two or more divers would be able to maintain track of the space between them.
