How about "A wireless communication device existing underwater"?

"A wireless communication device existing underwater" is grammatically correct, but it sounds less natural than "located underwater." Here's why:

1. "Existing underwater":

   • Feels slightly redundant because "existence" is implied when describing an underwater device.
   • It might be more suitable in philosophical or abstract contexts rather than technical or practical descriptions.

2. "Located underwater":

   • Direct and commonly used in technical contexts to describe the physical presence of something in a specific location.

Suggested Refinements:

• "A wireless communication device positioned underwater."
  (Focuses on placement, suitable for technical descriptions.)
• "A wireless communication device designed for underwater use."
  (Highlights purpose and context of use.)

If simplicity is key, "located underwater" is the most natural choice for general contexts.
