nope, if you come with your buddy.
but ask if they can fill your tanks with helium, and if they have a operator certified for trimix.
the operator must know trimix and/or rebreather security procedures to allow you to dive.
that's also for your security.
So basically, for my safety Im not allowed to be a more qualified diver than the guys I pay for the privilege of diving... makes perfect sense...
