Learning which type of underwater communications option best suits your needs is the first step in determining what system to choose.
What types of Underwater Communications are there?
To start, there are two choices of underwater communications: hardwired– uses a cable to transfer the communications, and wireless– uses the water to transfer the communications. While many divers prefer the idea of freely diving where they please with the ability to communicate wirelessly, this is not always the practical option for professional divers due to environment, circumstance, and function needed for the task at hand. Eliminating outside factors to affect communications, hardwired communications, much like a landline telephone, offers the highest quality and most reliable form of underwater communications. For this reason, hardwired communications work best in environments which have external factors non conducive for wirelessly transmitting. Furthermore, many professional divers in the Public Safety or Commercial Dive markets require tethering to a cable for safety applications which makes choosing hardwired communications a natural progression.

How do Hardwire Underwater Communications Work?
So how does it work? The diver’s earphones are connected to the ComRope which has the communication wires in its core and the ComRope ties in directly to a surface station of your choice. This provides clear and steady communications like a landline telephone. Because the communications are directly fed through ComRopes to the diver, you will not experience intermittent or lost communications. Furthermore, with options like the ability to add multiple divers to a systems as well as choices such as round robin communication, we’ve worked hard to ensure you will have the flexibility to build the system that fits your needs!
