Stroke

Topspin Forehand

Matt Jones, Assistant Head Coach of the Surf and Turf Tennis Club shows how to hit powerful forehand strokes by loading the legs and creating a wall with the racket head. This is achieved by aiming for a racket speed 13-15 mph above the ball speed.

Topspin Backhand

Coach Jones give pointers on increasing the ball speed of your backhand by keeping the racket head low and getting under the ball. Aim for a ball speed 10 mph above racket speed.

Slice Forehand

Slice Backhand

Volley

Volley Forehand

Sharpen up your volley by leading with the racket frame and increase contact with the ball. The goal is to get a ball speed of about 8-10 mph over swing speed and a ball spin of -6.

Android Wear smartwatch (optional)

Used to show the data while on the move easier.

Bluetooth speaker (optional)

Used to hear the sounds of the app more clearly.

Preparation

These are a list of steps to take before you get out on the court with your student.

Pair sensor with tablet
Make sure you having a working setup with the sensor and the tablet especially if this is your first time using it.
Sign into SEN while in a wifi zone
Doing this step of the initial setup requires wifi, so complete this before you are out on the courts.
Add tennis rackets that you and students will use during lessons
Add the tennis racket brands and models you have and think that your students will use with the sensor to the app.
Get tripod setup to hold tablet
Adjust the tripod mount on the tripod to hold the tablet in landscape mode. This will allow for better videos.
Charge everything
Make sure that the tablet, sensor, battery backup and whatever device you will be using has a full charge and are ready to go.

Student Selections

This is some things to look for in students that might make good candidates for using the sensor in their lessons.

Tech enthusiasts
Students that are interested in technology will be interested more in seeing their swing measured.
Students that are really looking to improve their game
A student that is motivated to improve their game will appreciate what value the sensor brings to the lesson.
Intermediate level or above that can benefit from the data
An intermediate level student is at the level that additional information the sensor brings is meaningful and they can use it to help them improve.
Early teens seem to respond well to the data and treat it like a video game
Students in their early teens love video games and the data the sensor brings to the lesson can be used to motivate them to "beat their score" and become a better tennis player.

Timing of When to use Sensor in Lessons

Timing of how frequently a student will benefit from a sensor based lesson will vary with the student. This is just a guideline.

Use sensor in intervals when student takes frequent lessons
This will give data and improvements in steps and not occupy lots of time for all lessons. Traditional lessons can be run in between the sensor based lessons giving more time to work on technique. Even those lesson can have the sensor attached and gathering information about that student, but the data does not need to be reviewed during that lesson.
Guideline is once every 3 lessons
If you go over the data with the student in every third lesson, they can see improvements.

Explanations

This will give some pointers on how to initially explain to your student what the sensor is and how you will use it.

Give brief explanation of what the sensor does and what data it records
Give a short description of the sensor and that it measures racket speed, ball speed and ball spin. It also knows where on the racket each shot is hit.
Say what you will be recording with the tablet and how you will use it later in the lesson
Describe that you will be recording video and that you will review it later with the numbers to see how they are doing.
Don't get in depth in the explanations
Don't bother to get too in depth up front about what they will see later. It is much better and more understandable when they see what their own video and numbers are.

Prepare Racket

This section applies to if you are using the student's own compatible racket during the lesson.

Remove butt cap logo from racket and install plastic ring to attach sensor
Use the little screwdriver supplied with the sensor to help remove the butt cap logo from the tennis racket. Then push in the appropriate plastic ring to the racket so the sensor can be attached.
Select correct racket and right/left handed in the profile
In the profile section of the app, select the correct model racket and if the student is right or left handed. This is important to get accurate data.
