I was looking for a new watch. Then I asked myself, are there any major technical differences in the hardware between the Fenix, Taxtic or D2? For example, the tactical features or the aviation maps should also be available for the fenix? Isn't it all just software, it shouldn't be a problem to programme in such things or e.g. the kill switch on the Fenix? Is it all just so that you have to pay more or are there actually differences in the hardware that prevent this?
