You need one Advance Unit for each person you wish to be in communication with. 

Our standard set of 2, Advance Unit package, is shown above (SKU: A02R).

You can connect up to 4 total users into a conversation. (6 people can connect with limited range.)

You DO NOT need your cell phone or a wireless network to connect.  Our Advance Units connect with one another without the need of a cell phone or wireless network. All our Advance Units are compatible with one another.  This means at anytime you purchase an Advance Unit, if you purchase one at a later date, it will connect with the unit purchased earlier.  

You can add on additional users at any time by purchasing additional Advance Units (SKU: A01R). Our single unit package is shown below.

What's Next?

Next step is to select the headset you wish to plug into your Advance Unit.  Your headset has the microphone and speaker.

Our headsets are specially designed with a secure waterproof connection.  It is up to the customer to always make sure your headset is securely tightened at all times during use. We have a selection of headset’s that are completely waterproof with IPX7 rating.  We also have a selection of weather resistant products with IPX5 rating. Our headset microphones have superior wind and noise cancelling technology designed to be used in extreme conditions.

Lastly, if you wish to use a headset from another source, all you need is a multi-connector to keep your Advance Unit sealed from any water intrusion.  (The headset from another source will not be waterproof.)

Below are the headsets we offer.

Where Does My Advance Unit Go?

Customers have multiple different options on where you can mount your Advance Unit.  The higher the Advance Unit is mounted, the longer your range is for communication. 

You can easily move your Advance Unit from one location to another.  This gives the customer the flexibility to use their Advance Unit anywhere and for any activity. You can mount your Advance Unit on a helmet, hat, arm band or clip. You can place your unit in your pocket, on your life vest or on your snow goggles.  Simply put, your unit is light weight, portable and can be put anywhere.

When on the beach coaching, you can mount your Advance Unit to a Telesin Pole for extended height and range. 

How It Works

Our Advance Units connect using built-in long-range Bluetooth, FCC approved.  The Bluetooth built into our units have significantly longer range than normal Bluetooth devices.  Your normal Bluetooth device range is only 20-25 meters.  In the optimal situation, our Advance Units’ Bluetooth range is 1000 meters (1 km) for a two-way communication.  The more units you add, the less range you will achieve.


Our Bluetooth frequency is 2.4ghz.  Bluetooth frequency does not go through water, waves, snow or any obstacles.  This is because Bluetooth connects by line of sight.


To obtain the best range using our units, you need to have the unit mounted in the highest position. 


When using our units in the water, if your body is submerged and the unit is close to the water, your range will be shorter until you get on plane.  If the Advance Unit’s antenna gets close to the water, the signal will be very weak.  When using electronics on the water, any signal will be very weak when close to the water. 


If your unit becomes completely submerged, you have 20 seconds to bring the unit back up out of the water.  Failure to do so will disconnect your units from one another.  If your units become disconnected, simply come within 200 meters of one another, then press one of the channel buttons to re-connect.

When connecting more than two Advance Units, they connect in a chain.  If you break the chain, your connection will also be broken.
