Sea Signs
Communication alternatives have limitations.
There are many forms of underwater communication on the market today, such as specialized gear and slates. Special gear is very expensive. Using slates can be awkward and slow. Even the hand signals commonly taught lack an adequate vocabulary to truly communicate effectively. Hand signals also can vary widely between agencies which can create confusion between two divers trained by different agencies.
SeaSigns is simple, inexpensive, and of broad scope.
SeaSigns offers a simple and inexpensive solution. Based on American Sign Language we have created a special vocabulary for scuba divers that is easy to learn and easy to use. Our vocabulary is much broader in scope than other hand signal methods.
Pricing: $125 (add on $30 for PADI specialty)
