Hi again!
The Scubasure policy covers you to dive to whatever depth you are qualified to dive to for a set premium. For example Joe Bloggs who is qualified to dive to 30m pays the same as John Smith who is qualified to dive to 45m. The premium doesn't vary and you are covered for any depth as long as you are QUALIFIED to dive to that depth. Hope that is all clear now.
With regards to the bungee jump - you're brave!

I will have to check this with the underwriters to see if it would be covered. If not we have a policy through PJH called Adventures which covers you for specific activities and can be used as a bolt-on to travel insurance.
I will check if you would be covered through Scubasure and, if not, I can give you an 'Adventures' quote.
