Review Extra: Divebud – Acoustic Freediving Computer


With advancements in Technology and the rapid growth of Freediving as both a recreation and competitive sport, Dive Computers are now integrated with advanced “freediving” specific features.

Divebud is at the forefront of this technology. The Australian-based grassroots company is owned by Freedivers and established for Freedivers. They have applied their years of professional experience to create a device that is compact, reliable, user-friendly, and “hands-free.” Their vision is to support the most critical element of Freediving…Safety.

Designed to be placed inside a dive hood or worn with a clip on the mask strap, this 0.150kg “bone conductive” device enables minimal distraction to the diver. Because of its lightweight, the company emphasizes the importance of utilizing the included lanyard inside the hood so as not to lose it.

Divebud founders believe “your data belongs to you” with a storage capacity of up to 50 dive logs directly on the device and “unlimited” storage via the free IOS and Android Divebud apps.

They have all but eliminated the Freediving variable concerns associated with checking traditional wrist-worn Computers such as:

  • Reduced visibility below 10m (especially in lakes and freshwater springs)
  • Breaking Streamline posture necessary for a proper glide in freefall and dynamic
  • Disciplines requiring the use of hands (i.e. No Fins and Free Immersion)

Alarm Features

Up to 20 Ascending and Descending depth alarms and six different sounds (vibration model available) can be customized to support practically every desired alert, with more features currently in development.

  • Surface Interval (AIDA Standards)
  • Neutral Buoyancy
  • Mouth Fill and Freefall
  • Hang at Depth
  • Ascent Intervals
  • Positive Buoyancy Point
  • Total Dive Time
  • Time-based (For pool training i.e. lap time and kick cadence)

Reliability and Accuracy

Divebud comes with a custom USB-C magnetic charger (up to 6-hour battery life upon full 3-hour charge), mask mounting clip, lanyard, and case.

Developed over 6+ years, it has a maximum operational depth of 150m/45m and has been repeatedly tested to 200m+/60m+.

With a Depth Measurement Sampling rate of 2x per second, accuracy is unsurpassed.

Like any new product to market, there is a lot of development going on with Divebud, and here are some of the recommended improvements.

  • GPS Device Tracking
  • Discipline Variable Log (i.e. Monofin to Free Immersion)
  • Sensory Alerts (i.e. lactic acid upon Ascent)
  • Vocal Signal Options
  • Heart Rate Alerts

Personal Thoughts

For many, Freediving’s appeal is the need for minimal equipment for a safe and enjoyable experience. Being the Founder of 321Freedive, and having trained with and served alongside some of the best Freedivers in the world, I carefully research and set my standards high when choosing equipment. The beauty of Divebud, is how it can be utilized by Elite and Novice Divers equally for both accuracy in training and, more importantly, safety.

NOTE: Freediving World Record Holders currently utilize divebud technology, and is under consideration as a collaborative tool in Research & Development to better understand DCI (decompression illness) and Freediving related Barotrauma.
