WHAT OUR CUSTOMERS THINK

"Hockey is a really intense game, I've taken big hits before and when the adrenaline is pumping you don't really notice it. This indicator will give you the peace of mind to play your hardest. The Tozuda Head Impact Indicator allows coaches and everyone to see right away when a bad hit has happened. I'd recommend this product to any hockey player on any level"

Ben Smith / Former College Hockey Player

"Seeing your child get hit at a high rate is probably the most nerve-racking part of (football). But the Tozuda Head Impact Indicator is a great tool for us to play smarter and safer. It gives our staff, myself, parents, if we notice someone's indicator is red, we can get them off the field and checked out. Tozuda is an excellent tool that we can use to help us on the sidelines."

Steve Martel / Football Parent & High School Coach

"I see my kids hit their head often, and you don't always know if you have to bring them to the doctor. It's really important to us that our daughter has her Tozuda Head Impact Indicator on her helmet so when she fell and hit her head we knew whether or not we needed to get medical attention. I would definitely recommend it for other moms, and even adults because knowing if your own brain is okay is also very important."

BUILT FROM EXPERIENCE

As Founder and CEO of Tozuda, Jessie Garcia knows from experience how devastating head injuries can be. Formerly a collegiate rugby player, Jessie experienced a hit during a game and kept playing, only realizing later on that the impact was more serious than anyone knew in the moment. Frustration in dealing with long-term effects of an injury that she felt could've been avoided forged the path for Tozuda - designing, manufacturing, and selling head impact sensors to provide clarity in the uncertain world of head injuries. At Tozuda, we want everyone to have the freedom to do what they love without the fear of making the wrong call after a hit.

FREQUENTLY ASKED QUESTIONS

Have Questions? We’re Here To Help

WHAT ARE IMPACT INDICATORS? WHAT ARE THEY DESIGNED TO DO?

Impact Indicators are devices that alert a participant or bystander when someone has been hit too hard during their activity. Tozuda's Impact Indicator can attach to any type of helmet with only double-sided tape.

Impact Indicators are NOT designed to detect or prevent concussions. Impact Indicators are designed to detect or react to linear and rotational accelerations that the head may undergo. When a dangerous threshold has been reached, users and/or bystanders are alerted through the indication of the Impact Indicator when it turns colors from clear to red.

If there is any indication that a head injury has occurred, seek medical attention as soon as possible. Only a licensed medical professional can legally and properly diagnose a concussion.

WHAT MAKES TOZUDA DIFFERENT FROM OTHER IMPACT INDICATORS?

While there are other impact indicators on the market, Tozuda beats them all with its patented mechanical technology that allows for no electronics and an instantaneous indication, while being user-friendly and affordable.

HOW DO I GET STARTED?

Once you purchase and receive an indicator, carefully remove it from the packaging, peel the sticker off the tape and place it on the back of your helmet.

WHAT IS THE LEAD TIME?

For orders with less than 48 units, processing time can take 3-5 business days and shipping can take an additional 2-7 business days.

ARE IMPACT INDICATORS ONE TIME USE OR REUSABLE?

Once the indicator activates, it is no longer usable, it has to be replaced.

WHAT DO I DO IF MY INDICATOR ACTIVATES DURING SHIPPING? IS THERE A WARRANTY?

See our Policies for more information.

HOW LONG DOES AN INDICATOR LAST IF IT HAS NOT BEEN ACTIVATED?

If an indicator has not been activated, then it can last for up to two years!

CAN I DONATE INDICATORS TO A TEAM OR LEAGUE?

Yes! We offer sponsorship programs where you can help to outfit a local sports team with indicators. For information about sponsorship opportunities, get in touch with us at sales@tozuda.com

WHAT IS AN "ACTIVATION" OR "TRIGGER"?

When you first receive your indicator, the spring should be in a straight alignment. The indicator is activated if there is any displacement to the ball-and-spring system.

When activated the middle chamber will begin to fill with red color. Any concentration of red color in this chamber signifies an activation."
