Hi Reeve, you will get a lot from the course-if you can do the skills over here, france or florida will seem a whole lot easier. Although trust me, zero vis in a cave is VERY different to in the ocean-and being tied up in your line and having your light turned off makes for a new meaning of fun! Seriously, even if you dont do on to cave dive it will give your whole diving a boost and you'll never trust your kit again
let us know how it goes-I've gone to florida to train to cave dive both sidemount and with the inspirtion and I'm just starting to do some over here after 'dry' caving for a couple of years.
