Congratulations on your certs! Oronogo is a fun place to dive, and they do have rental gear there as well, ie. 6/7 mm wetsuits, bc,...etc. I dive wet 6mm and stay pretty comfy. You will want gloves tho', took me one dive to figure that out!

You can also find them at
Captain Johns | Oronogo, MO However, they haven't updated it since October....one my pet peeves. I haven't been there to dive the new season yet, but it was $12 to get in and just dive, then what ever gear you need... air fills were 4 dollars I think. Maybe Dark Wolf could verify that. All in all, I enjoy it, they have sunken boats and an airplane to look at, and vis is usually 5-15 depending on weather and #of divers on a given day. They have a school bus that has been sitting on blocks for a while now.... maybe they will sink it sometime soon.
Happy Diving-
