Constructed using the same rugged materials that go into the entire line of iKey peripherals, the NEMA 4X AquaPoint industrial pointing device features a sealed industrial silicone overlay and robust polycarbonate frame. Its reliable optical technology allows it to function on most surfaces, while its smooth-surfaced buttons make the unit easy to clean. Solid-state engineering ensures the AquaPoint a long operating life, making the new device the ideal alternative to the office-grade mice that are so commonly replaced in harsh environment settings.
