This is different for everyone? Why?
Because we all have different tolerances to the risks we naturally face whilst enjoying our love of riding/driving competitively or simply enjoying the passion for recreational use.
As previously stated – The Helmet Doctors recommends having your helmet scanned (as a bear minimum) once a year, if your helmet is used for general use only. However, if during that year you are subject to an incident of any kind of impact, dropping it from the bike/car or garage self while stationary then of course we advise to have them re-scanned.
But as you can imagine, for those who use their helmet weekly, competitively and or for more than your regular recreational events, those particular helmets will be subject to more likely events of impacts that you may not even be aware of.
So, … for people in this category, they might have more peace of mind having their helmet scanned twice a year yet a similar person with a less tolerance to these risks might like to have their helmet scanned quarterly. It really depends on the owner.
There is no right or wrong answer.
The only thing The Helmet Doctors will say is, by having your helmet scanned regularly, you are significantly increasing your chances of identifying a potential defect which may just save your life.
This alone will exponentially increase your protection and give you the peace of mind that your helmet has not been structurally compromised.
