I watched the video on getting the CTX ready to hunt in the water. From this video they infer that the red seal is simply protecting the battery. It also seems the computer guts are protected already except that water could enter through the coil and screen cable connections. The underwater headphone connector is sealed inside as well, and the only reason you would seal that is if you are not using the underwater headphones to keep sand out. Then you have the usb port on the back of the screen head to seal. Do I have it correct?
