Deep Dive Analysis: Scuba Diving Magazine Reviews the DIVINTOK Dive Transceiver
When new gear hits the diving market, whether it's for recreational or technical diving, safety is always the top priority for divers.
At the recent ADEX Beijing show, DIVINTOK partnered with PADI to host the launch event for their Dive Transceiver. During the event, DIVINTOK introduced divers to the transceiver's specifications, diverse use cases, and the noteworthy safety test results that deserve careful consideration.
Scuba Diving is a renowned magazine dedicated to diving activities, with its online site receiving over 278,000 page views per month and 240,000 divers subscribed to the Scuba Diving eNewsletter. In the August issue of Scuba Diving Magazine, they featured a brief review of the rising star in underwater communication devices—the DIVINTOK Dive Transceiver.
Since November 2021, within a span of three years, DIVINTOK has been the only underwater communication product featured in the "Quick Looks" section of Scuba Diving Magazine. Additionally, since January 2021, PADI Magazine has not featured any general-purpose underwater communication products that aren't integrated with full-face masks.
The DIVINTOK Dive Transceiver has filled this gap, with its compact and universal design allowing regular divers to communicate freely underwater.
The DIVINTOK Underwater Transceiver-Mini consists of an Underwater Receiver and a Mouthpiece Microphone, with the Mouthpiece Microphone connected to the second stage of the diving regulator. Since the Mouthpiece Microphone functions as a breathing accessory, it is crucial to test its breathing resistance and CO2 washout performance.
These tests help determine the equipment's performance under various conditions, ensuring that divers do not face safety issues like breathing difficulties or CO2 buildup while underwater.
Professional Testing of DIVINTOK Dive Transceiver
Testing Methods and Results
1. Work of Breathing (WOB) Test
Researchers at DiveLab utilized a breathing simulator to replicate various breathing rates and tidal volumes, measuring inhalation and exhalation pressures with and without the DIVINTOK Mouthpiece Microphone. Results indicated that installing the mouthpiece had minimal impact on inhalation and exhalation pressures, ensuring stable WOB levels.
Key findings:
· The DIVINTOK Mouthpiece does not significantly increase breathing resistance.
· The Mouthpiece Microphone maintains diver comfort under varying conditions.
The above chart shows the WOB data for the regulator alone under the 22.5 RMV condition.

2. CO2 Washout Performance Test
This test assessed inhalation and exhalation pressures alongside CO2 concentrations at different breathing rates:
· Low rate (10 L/min): CO2 concentration averaged 0.42%, demonstrating effective washout.
· Moderate rate (22.5 L/min): CO2 concentration rose to 1.18%, remaining within safe limits.
· High rate (40 L/min): CO2 concentration reached 1.95%, confirming efficient CO2 clearance even under intense use.
These results confirm the mouthpiece’s ability to maintain low breathing resistance and effective CO2 washout across different conditions, ensuring diver safety and comfort.
Testing is a crucial step in ensuring the quality of diving equipment. The DIVINTOK Dive Transceiver not only excelled in professional testing but also maintained ongoing interaction with the diving industry throughout its development and market cycles, inviting divers to participate in extensive underwater testing.
Development and Testing Timeline
October 2019 – May 2021: The DIVINTOK team initiated technological research, completing the product concept after 19 months.
October 2021 – February 2022: The first-generation prototype underwent real-world testing in pools, lakes, and controlled environments. Experts were engaged to refine design, operation, and underwater performance.
