We met marine educator, conservationist and activist Jacqui Younger at Blairgowrie Yacht Squadron to try out the Nemo by Blu3, a battery-powered tankless dive system, for underwater cleanups of the pier. 

The Nemo Blu3. It is a middle ground between snorkelling and scuba diving. 


Jacqui uses the system so she can complete a more thorough clean of fishing gear wrapped around the kelp and sponges at piers in Melbourne's  Port Phillip Bay. Jacqui is an education office at Dolphin Research as well as involved in all sorts of projects to do with the local coastal environment. 

The Nemo Blu3 is a battery powered dive compressor that floats on the surface and delivers an air supply to a maximum of 3m underwater. It allows the user to remain submerged for up to an hour or more on a single charge (which takes about 3 hours)


Diving - even to a depth of only 3 meters - can involve dangers/risks if you just "jump in" without any training. Therefore, Nemo comes with a thorough and good online course and printed manual in the product box (more on that below). If you want to buy a Nemo by BLU3 you must be able to swim 200 meters and "tread the water" for 10 minutes. Age Limits: Users under 18 supervised by an adult at all times. Users must be over 10 years of age to use the location other than the pool. Users between 8 and 10 years only in the pool, at a depth no greater than that they can stand with their heads above water. The two most important things about safe Nemo diving are to always breathe normally / exhale during ascent, and often train to quickly release the lead belt. (practice picking up / putting on the buckle, and sometimes releasing it)

More about the Nemo by Blu3

All Users must be able to

  • Swim 200 metres without stopping, without a time limit
  • Tread water for 10 minutes continuously

Age Limits

Before using Nemo

Nemo by BLU3 comes with a very thorough web course we want you to complete. It deals with safe diving with shallow air in shallow water in general, and the use of Nemo. This course is currently available in English only. When purchasing Nemo you must at the same time confirm that you read through "medical declaration" (link listed below), that you read and sign BLU3's disclaimer (link listed below) and that you must complete the online course on the link below. Only after completing the online course will your Nemo be covered by a 1-year warranty. You agree to this when you confirm that the course will be completed.
