1. ABOUT YOUR eo SwimBETTER
1.1 INTENDED USE
Purpose built to help improve your swim
technique, eo SwimBETTER is worn
on both hands to measure the forces
generated as you swim. Fitting neatly in
your palms, the eo SwimBETTER handsets
collect a host of additional data, including
your hand path and velocity, stroke
rate, stroke phases and consistency.The
collected data is downloaded to the eo
App on your mobile phone for analysis and
stroke intervention right on the pool deck.
eo SwimBETTER is intended for use in
indoor and outdoor chlorinated and salt
water pools and can be used by swimmers
of any age or experience level who are
looking to improve their swim technique.
1.2 WHAT’S IN THE BOX
Everything you need to SwimBETTER

2. in temperatures from -10°C (14°F) to 40°C (104°F).
NOTE: When using eo SwimBETTER outdoors when the sun is shining, you need to clip
the Sunscreens included in your kit over each handset.They shade the pressure sensors
which are sensitive to light without hindering their ability to measure the pressure
(forces) during the stroke.
Size Each handset is 11cm x 4cm x 1cm (4.3in x 1.5in x 0.4in)
excluding straps.
Weight Each handset weighs 30g (1.06 oz.) that’s about as much as a
slice of bread.

Operating Instructions | 6
2. SET UP AND GET STARTED
2.1 ATTACH YOUR STRAPS
1. Place the handset face down with the
sensor band facing away from you.
2. With the eo logo on the strap facing
up, feed it through the hole from the
inside of the sensor band until the
orange strap clip clicks into place. When
it’s clicked in correctly you will have
a smooth finish on the inside of the
sensor band.
IMPORTANT: There is a little key on
the orange strap clip that clicks into
the sensor band.This will click in with
minimal pressure if you have the strap
facing the right way – please do not
force it. If the strap doesn’t click into
place easily, check you have the strap
the right way around and try again.
3. In your straps bag, you’ll find two
orange keepers.These will help hold
your straps closed during your swim.
Slide one of these onto the strap.
4. Now feed the other end of the strap
through the hole on the other side of
the handset.
5. When the strap wraps around your
hand, the velcro should connect to the
strap. If it doesn’t, you’ve got it back-to-
front.Take the band out, flip it and try
again.
2.2 PUT YOUR HANDSETS ON
The most important thing is to make sure
you put your handsets on the correct
hands.You’ll see an L and R hand reference
on the back to make this easy.
This is what they look like when on
correctly – the eo logo should read from
left to right when you’re looking at your
palms.
1. Sit the body of the handset into the
hollow of your palm.
2. The sensor band wraps around the
outside (pinkie side) of your hand.
3. Adjust the velcro straps for a firm but
comfortable fit. Ensure the straps are
secure by sliding the orange keeper
over the end of the strap. If your straps
come loose during a swim, it could
impact the quality of your data.
4. Avoid placing the straps across your
knuckles as this can cause them to
release when your hand flexes as you
swim.

2.3 SET UP YOUR APP
1. It’s important to set up your App
and complete the Your details, Your
locations / pools, and Device setup
sections before you record any swims.
These steps will link your handsets so
they’re ready to record.These steps only
need to be completed once, however,
additional pools can be added at any
time.
2. If you haven’t already, you first need
to set up your eo Account.You can do
this at eolab.com by clicking the Login
menu link – second from the right at the
top of the screen.
3. Download the iOS or Android eo
SwimBETTER App from the App Store
or Google Play. Click one of the icons
below or search for eo swimbetter.
4. Login with the email and password you
used to set-up your eo Account.
5. On your first log in, you will be taken to
the Your details page. It’s important to
fill in this information before your first
swim so your data is properly reflected.

measurements here. If you don’t have
a ruler or tape measure handy, just take
your best guess.

Operating Instructions | 8
7. Now it’s time to set up your pools. Click
Your locations / pools on the Home
Screen and fill in the details of the pools
you regularly swim at.You can add as
many pools as you like, but you will
need to have at least one listed before
uploading your first swim.
8. Next up, you need to pair your
handsets. We recommend doing this
at home where there aren’t any other
handsets in your vicinity.

the list, by matching the serial numbers
with the ones that are printed on the
back of each of your handsets - this is
the large number that appears below
the L and R.
10. Hit the +button alongside your left
handset.You’ll then be asked to name
your device - call it whatever you like -
then click done. Do the same for your
right handset.

2.13 TROUBLESHOOTING
What the f*@k - something’s not right!!!
App issue User instruction
I’ve uploaded my data
but it’s not showing up
in my list of swim
sessions.
This could be one of two things. First, check that you have
available mobile data or are connected to Wi-Fi so your
swims can transfer to the Cloud. Once they have transferred
to the Cloud they can take a couple of minutes to show up
under Your swim sessions.
If that’s not the problem, then it’s likely you weren’t under
water for long enough before taking your first stroke. The
handsets need to be under water for a minimum of
2.5 seconds and then you must take at least 3 strokes for
your stroke analysis to begin.
My hand path data looks
very strange. It shows
my hands shooting off
in odd directions which I
know is not correct.
This is likely caused by your hands being twisted or your
arms not being straight in front of you while you were doing
the Pool Orientation.
Try redoing the Pool Orientation and ensure you follow
these instructions carefully:
1. Position yourself at the end of the pool, facing down the
lane in the direction you are about to swim;
2. Press the button on EACH handset to start Pool
Orientation;
3. Place your hands in the Pool Orientation Position:
• Palms facing up, parallel with the water,
• Fingers pointing in the direction you’re about to swim,
• Hold your palms level, steady, and facing directly up,
with your elbows tucked into your sides.
Your LED(s) will turn solid green when Pool Orientation has
been completed successfully. If your LED(s) turn back to
solid purple, the Pool Orientation was unsuccessful and you
need to try again.

Operating Instructions | 17
I’m trying to record
but the LED on one, or
both, of my handsets
is yellow.
Your memory is full. Better
download your data so you can get
back in the pool and record some
more.
Left LED Right LED
The LEDs are doing
strange things. One is
blinking and the other
is solid.
Yeah, that is strange. Turn them off
and try again.
Left LED Right LED
I’m trying to take
the pool orientation
reference, but my
LED(s) keeps turning
back to solid purple
OK, this could be one of two things:
1. Check that your hands are level,
facing straight ahead, and the
eo logo is facing directly up.
2. Check you’re holding your
hands still for long enough. The
handsets need a second or two
of stability.

My handsets are on
charge, but the LED is

Check that the charging clip is
located correctly with the charging
pins connecting to the charging
plates in the sensor band. Give the
clip a gentle wiggle and you should
feel it click into place. That should
do the trick.

If all else fails, turn your handsets off then back on, and / or relaunch your App.
