I have an Aquatica 5D MII uw housing. The problem I have is the engagement of the rubber wheels that engage the dials. The rubber wheels in the housing tend to slip and/or not engage the camera controls properly. I wish there was a way to replace the rubber wheels in the uw housing with something that more firmly engages the dials and switches on the camera. This may be a combination of making a piece that goes over the camera dials (e.g. mode dial) and also replaces the uw housing rubber wheel that engages the these dials and switches. The camera dials can be tough to turn some times and the rubber wheels tend to slip/wear out over time.
