For those times that you just have to shoot up close in wet environments and still need camera movement then perhaps the WDX all weather ocean going Mini Slide slider would work for you. The WDX Mini Slide slider combined with small cameras such as the GoPro Hero 3 is suitable for Food Process, Pharmaceutical /Biochemical, Medical, Magnetic Sensitive Equipment, and Marine Instrumentation environments.
