Hello,
Not every computer on the 2.4 GHz ISM band will work with ANT+. Only a bike computer that is ANT+ compatible with work with an ANT+ sensor. Unless the product specifies that it is ANT+ enabled, it will not work with ANT+ sensors.
It doesn't appear as though the Cateye computer that you linked to is ANT+, it seems to use it's own propriety protocol.
I can't comment on other Cateye computers, perhaps that is a question you can ask them directly.
Cheers,
Kassandra
