Kona Coast Hawaii shore diving (need info)

Hi All.
We are heading to the Big Island in December, and my son and I want to try
shore diving in Puaka Bay. We normally do boat diving, but for the cost,
this looks like a great way to do
it.
First off, anybody experienced with shore diving at Puaka bay, and can you
give us any pointers.
Second, is there a good spot to rent tanks and weights that is close by
(Kohala)

Thanks in advance.
Randy
