Oar Kit · Assembly & Mounting
Assemble your oar kit.
Assemble each sensor in its housing, secure both mounts to the oar, then use the guided motions to align them. The same kit works with iOS and Android recording.
Parts for each sensor
Lay out the parts below. Repeat the same assembly for your second sensor.
- A Sensor
- B Housing
- C Two side clips
- D Flexible ring
- E Curved saddle
- F Strap
The curved saddle snaps flush into the matching curve at the back of the housing, then rests against the oar. The drawings below show how the parts engage.
1Fit the two clips
Start with the empty black housing. Hook the retaining flange of one yellow clip over the matching housing edge, then press the clip fully home. Fit the second clip on the opposite side, with its flange toward the housing.
Check that both clips are seated and their long strap slots are unobstructed.
2Fit the ring and sensor
Stretch the flexible ring around the outside edge of the sensor. Keep it even around the sensor rather than twisted or bunched at a corner.
Insert the sensor through the open back of the housing. Press it in evenly so the button and logo face remain visible through the front opening. Check that the ring stays seated as the sensor goes in.
3Add the curved saddle
The saddle goes on the curved back of the housing, between the sensor and the oar. The housing and saddle have matching curves, so they nest flush together. The concave outer face rests against the shaft.
Engage one edge lip, then gently flex the opposite edge until it snaps into place. Check that both lips are engaged, the saddle sits flush with no gap, and the sensor remains seated.
4Strap it to the oar
Place the saddle against the shaft and wrap the strap around the oar. At each yellow clip, feed the strap through the slot from the inside (the oar side) to the outside. Fold each end back onto the strap on that same side and press it firmly onto itself.
The strap has hooks and loops together on one face; the other face is smooth. Keep the smooth back against the oar, then fold each end back without twisting so the two fastening faces meet.
The mount should stay put when you gently try to slide or rotate it. Check it again after feathering and squaring the oar.
Position and direction
- Place one sensor between the handle and the oar button, and the other on the blade side of the button. Keep mounts clear of the oarlock and your hands.
- Orient both sensors along the shaft with the offset sensor button toward the blade. That is the sensor’s −Y direction. The sensor’s +Y direction points toward the handle. With the oar held vertically, blade down, +Y points upward. Keep the button face visible.
- Use the actual sensor positions in your oar details and stiffness setup. Moving a sensor changes the setup.
Next · Motion Alignment
Align with a few deliberate movements.
With both mounts secure, record the still, feather/square and sweep movements. The app or Cloud Analysis uses them to learn how the sensors sit on this oar.
Use this motion alignment after mounting or repositioning a sensor. Oar stiffness calibration is a separate step that sets the Moment/Bend Factor used for moment, work and power.
Before the first workout
Confirm the active oar name, side, sensor identities and sensor positions. Save the motion alignment and the stiffness calibration for that setup, then make a short recording to check both sensors. Repeat alignment and review the stiffness setup whenever you move a sensor.
A phone used for boat motion needs a secure hull mount. Follow the iOS recording guide or Android phone-motion guide for the data to record.
