Key takeaway: BbTalkin 3.0 and the Milo Action Communicator are the two most recommended waterproof intercom options for watersports, and they are built around opposite ideas. BbTalkin puts a speaker at your ear through wired waterproof headsets and structures groups around a coach. Milo is a clip-on unit with a built-in speaker that groups itself automatically over a mesh network. Which one fits you depends almost entirely on whether you are coaching or cruising.

What Is the Milo Action Communicator?
The Milo Action Communicator is a compact 72g voice communicator that clips to a helmet, strap or handlebar and connects to other Milo units over MiloNet, a proprietary mesh radio network. There are no buttons to press to talk and no phone signal is needed. Milo carries an IP67 rating, meaning it is dust proof and submersible to 1 metre for 30 minutes, and Milo states it has been tested to 3 metres for short durations.
Milo publishes its specifications openly, and every Milo figure in this comparison comes from Milo's official tech specs and Milo's support documentation and product listing. Where Milo has not published a figure, this article says so rather than guessing.
What Is BbTalkin 3.0?
BbTalkin 3.0 is a waterproof Bluetooth intercom system built around two unit types and a family of wired waterproof headsets. The Standard 3.0 handles 2-person communication at up to 1000m in open conditions and pairs with a smartphone and GoPro HERO 12. The Master 3.0 is the group controller that connects up to three Standards for coaching sessions. The Master cannot pair with a phone or GoPro; only the Standard does that.
Every BbTalkin unit is rated IPX7 with a sealed screw case, withstanding submersion in 1 metre of freshwater for 30 minutes per the IP code standard. Audio runs through wired headsets: a Surf Cap, Surf Hat or a helmet pad mounted inside a water helmet, so the speaker sits at your ear rather than somewhere on your gear.

Where Milo Is Genuinely Strong
An honest comparison has to start here, because Milo does some things very well. MiloNet grouping is the standout: units find each other and form a group automatically, with no controller and no pairing sequence. For a mixed group of friends splitting a day between bikes, snow and water, that convenience is real.
Milo also supports larger groups. Up to 8 connected units against BbTalkin's 4 is a clear win for big social rides. The single-unit design means one 72g gadget per person and nothing on your head, and the IP67 rating adds a dust-proof rating alongside water protection. If your sessions are casual and social rather than structured, Milo is a genuinely good product.
Where BbTalkin Wins
Audio at the ear, not on your gear
The core design difference is where the speaker sits. Milo plays audio from the unit itself, wherever it is clipped. BbTalkin routes audio through a wired waterproof headset, so the speaker sits directly at your ear inside a surf cap, surf hat or helmet pad. In 25 knots of wind with spray coming over your shoulder, that distance between speaker and ear is the difference between hearing an instruction and asking for it again.
Milo does offer an optional Bluetooth headset connection, and Milo's support pages mention pairing earbuds such as AirPods. The catch is that most consumer earbuds are not rated for submersion, and an earbud that pops out mid-wipeout is gone. BbTalkin headsets are wired, waterproof and designed to stay on through a crash, which is exactly why schools specify them.
A group built around a coach
Milo's mesh treats everyone equally, which suits friends riding together. Coaching works differently. The BbTalkin Master 3.0 gives an instructor channel control over up to three students, and every unit remembers its pairings, so a school's kit works the same way every morning. One instructor, defined students, no strangers joining the session. That structure is why surf and kite schools across Europe standardise on the 3-person coaching kits.
A published battery figure that covers a teaching day
BbTalkin 3.0 runs 14 hours on a charge, a number that comfortably covers a double teaching shift. Milo states a full day of use under normal conditions and a 90 minute recharge, but publishes no hour figure. Milo may well last a session; BbTalkin tells you exactly how long it lasts, which matters when a school is scheduling gear across back-to-back lessons.
Phone and GoPro pairing for coaching content
The BbTalkin Standard 3.0 pairs directly with a smartphone and a GoPro HERO 12, so a coach can take a call between sessions and a rider can record intercom audio straight onto footage. Milo's app handles settings and updates and is not required for operation, which is elegant, but if recording coaching audio to camera is part of your workflow, the Standard 3.0 is the unit that does it.
What Full-Duplex Means and Why It Matters
Full-duplex means both people transmit and receive at the same time, exactly like a phone call, rather than taking turns as on a walkie-talkie. BbTalkin 3.0 is full-duplex and hands-free with no push-to-talk, so an instructor can interrupt mid-sentence the moment a rider starts doing something dangerous. In coaching, the ability to talk over each other naturally is not a luxury. It is the feature.
What This Looks Like on the Water
After seasons supplying surf and kite schools from Tarifa to Scheveningen, the Milo question comes up weekly, usually from an instructor whose group already owns a few. The pattern in the answer never changes: riders who mix sports casually keep their Milos and enjoy them; schools and serious coaching pairs end up on BbTalkin, because lessons live and die on whether the student actually hears the correction.
The pros make the same call. Steven Akkersdijk, CORE team kiteboarder and Red Bull King of the Air competitor, runs BbTalkin for live coaching feedback during freeride sessions. Jamie Overbeek trains for big air with a Standard 3.0 on his helmet, taking jump-timing input mid-session; the full setup is in the Jamie Overbeek record story. Both use cases share one demand: every word must arrive at the ear, first time, in wind.
Which Should You Choose?
| Choose BbTalkin 3.0 if | Choose Milo if |
|---|---|
| You coach, teach or train with a partner | You ride socially in a group of friends |
| You need audio at the ear in wind and spray | A speaker on your gear is close enough |
| Your group is 2-4 with a clear coach-student structure | Your group runs 5-8 with no leader |
| You want a published 14 hour battery figure | A full-day claim without hours is fine for your use |
| You want phone and GoPro pairing for coaching content | You want one gadget with no headset at all |
| Your headset must survive wipeouts and stay on | You mostly ride sports where you rarely fall in water |

The Verdict on the Milo Action Communicator
Milo is a well-made social communicator, and for casual mixed-sport groups it earns its recommendation. But the moment communication has a job to do, coaching a student, running a lesson, calling a jump, the design brief changes, and BbTalkin 3.0 is built for exactly that brief: full-duplex conversation, audio at the ear through crash-proof waterproof headsets, a 14 hour battery and a group structure with a coach at the centre.
Start with a 2-person kit for rider-and-coach sessions, or add a Master 3.0 to run groups of three or four.

Frequently Asked Questions
What is the difference between BbTalkin and the Milo Action Communicator?
BbTalkin 3.0 is a coaching-focused intercom that plays audio at the ear through wired waterproof headsets, while Milo is a clip-on unit with a built-in speaker that groups automatically over a mesh network. BbTalkin structures groups around a coach; Milo treats every unit equally.
Is the Milo Action Communicator waterproof?
Milo carries an IP67 rating, meaning it is dust proof and submersible to 1 metre of water for 30 minutes, and Milo states it has been tested to 3 metres for short durations. BbTalkin 3.0 is rated IPX7 with a sealed screw case, also covering submersion to 1 metre for 30 minutes.
Which has more range, BbTalkin or Milo?
BbTalkin 3.0 reaches up to 1000m between two units in open conditions, dropping to 300-600m in group mode. Milo's product page claims up to 1000m between two units, while Milo's own support documentation quotes about 600m, and no group range figures are published. On documented numbers, BbTalkin's 2-person range is the stronger claim.
How many people can talk at once on each system?
BbTalkin supports up to 4 people using one Master 3.0 and three Standard 3.0 units, with the instructor controlling the channels. Milo supports up to 8 connected units through its MiloNet mesh with no controller. Milo wins on headcount; BbTalkin wins on structure for lessons where a coach needs to lead.
Can BbTalkin or Milo pair with a phone or GoPro?
The BbTalkin Standard 3.0 pairs directly with a smartphone and a GoPro HERO 12, so riders can record intercom audio onto footage. The BbTalkin Master 3.0 does not pair with a phone or GoPro. Milo offers an optional companion app for iOS and Android and supports Bluetooth headset pairing, but the app is not required for operation.
Which is better for surf schools and group lessons?
Surf and kite schools are better served by BbTalkin because the Master 3.0 gives the instructor channel control, the wired waterproof headsets stay on through wipeouts, and the 14 hour battery covers a full teaching day. Milo's automatic mesh suits social groups better than lessons, where a coach needs to be heard clearly by every student.
