As mentioned in my GoPro HERO4 Black Edition’s post , GoPro doesn’t use the standard tripod mount unlike the Sony HDRAS20 Action Video Camera , and hence if you want to mount it to a tripod, you got to get the GoPro Tripod Mounts  which is retailing for S$20.
I got mine from Click! by Max Photo  which is located at Funan DigitalLife Mall  #04-15. They do accept CapitaVoucher  and I used my CapitaVouchers that my ex-colleagues gave it to me as a farewell present.
GoPro Tripod Mounts includes two tripod mounts: Normal Tripod Mount and Quick Release Tripod Mount
