Welcome to Dive Gear Reviews, a comprehensive guide to scuba diving equipment. Scuba diving is an expensive pursuit, so looking up reviews for a particular article of equipment is a wise precaution before investing any hard-earned money in it. However, consumer reviews may or may not be written by an experienced diver, and magazine reviews could be suspect due to the advertising ties of the publication in question. Dive Gear Reviews provides cross-referenced reviews assembled by an expert, making it possible to see at a glance what multiple sources said about a particular piece of scuba equipment. If one magazine loved a scuba regulator or a dive computer, but the consumers hated it, that information will be found here.

Scuba diving mask

New dive masks invariably come coated in a thin layer of oil. The manufacturer puts this oil on the mask to protect the silicon skirt, helping to retain its flexibility and full color while the mask is on the display shelf. The problem is that this oil retains moisture, so only a little of it will completely fog up your brand new dive mask. Even a defogging agent will have a hard time coping with even a tiny residue of fog-producing oil, so you must thoroughly clean the dive mask before using it.


Smear soft scrub soap or toothpaste over the entire interior surface of the dive mask, including both the lens(es), the nose and the skirt. Even though you usually only spit or spray defogging agent on the lens(es), any oil residue on the inside of the mask will produce fog. Toothpaste and soft scrub soap are the agents of choice because they are commonplace and won’t scratch the surface of the lens(es). If you own glasses and have a bottle of eyeglass cleaning solution, that works even better. Scrub the interior of the mask with your fingers, and rinse the mask out with freshwater. Then allow the mask to dry in the shade, just as you would after a dive. Once the mask is dry, check it by touch for oil residue. If any remains, repeat the process.
