For only $199, you can add the ability to measure vertical jump to any existing RM-510 Start gate. To upgrade, you will need to send us your existing gray boxes.

While we have your gates here, we will service them at no additional cost, including:

• Replace scratched lenses

• Repair broken power switch, tripod mount, as needed

• Replace any corroded battery contacts and adjust tension.

• Update the firmware to the latest version

After the purchase, we will send you a shipping label (only for the continental USA ). The turnaround is a couple of days after we receive your gate.

To use the Vertical Jump feature, set the timer mode in the app to Vertical Jump and place the S gate and one of the black boxes on the ground, 4 to 8 feet apart. Stand between the gates as shown in the drawing. Once the red light blinks slowly, you can jump. The app will also notify you when the gates are ready. Jump straight up and land between the gates, blocking the beam again upon landing. The timer computes your jump and displays the height on the app and the results table. Results are also sent to the Team portal if you are using a wristband.

If you continue to block the beam after your jump for about 4 seconds, the gates will automatically reset to zero, enabling you to jump again.
