The "bomber" is at the far Western end. All I have seen is the engine block (see below) which is in between 6m and 8m of water (it's all pretty shallow down there).
The pinnacles are as described in the Fresh Water Diver's excellent website. There is a gnome garden below 45m next to a couple of washing machines. That's as far as I've been but I've been told that it goes far deeper.
HTH, be careful.
