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.

Hollis DC4/221 Scuba Regulator Review

Written by Dive Gear Reviews Editor. Comments Off on Hollis DC4/221 Scuba Regulator Review Posted in: Between $251-$500, Scuba Regulators

This scuba regulator is the budget choice for divers who want the quality of the Hollis DC3, but at a reduced price. The first stage is essentially the same unit as the more expensive DC3, sans the cold water environmental kit. The same idea applies to the model 221 second stage, as it is a cut-down version of the 212 mouthpiece that is paired with the DC3. The result is a regulator that performs just as well as a more expensive cousin in breathing machine tests (both scored well), breathes easy and dry under conventional circumstances and unconventional positions, purges well and offers virtually no bubble interference. An added plus for such an economical regulator is the Nitrox compatibility, and the Hollis DC4/221 can handle mixtures of up to 40% oxygen. The sole downside is that stripping away those extra features makes it less suited to cold water conditions. So, divers who live in placed such as Vancouver or Scotland or who plan to make frequent dive trips to cold water destinations should pay the extra money for the Hollis DC3/212 or the product of another company. Divers who want a solid regulator for temperate and warm water use, however, can save themselves about $150, drop the cold water features and buy the Hollis DC4/221.

Average Price: $399
