I am new to this forum group so can use this thread as a bit of an introduction. I got into technical diving mainly because of my interest in wrecks, although I also enjoy interesting topography. I am currently not cave trained and don't really have any desire to cave dive . Having had a few years of trimix experience I recently started down the rebreather route and most of my dives for the next year or so will be aimed at getting time in on my unit.
