Gauges are not considered the most important when selecting your Regulator, However there are many different options available with plenty of different Features.
Despite Computers coming onto the Market that have seemingly replaced the use for Depth Gauges and SPGS, it is still the opinion of many divers that a console Gauge is a Must especially as a backup SPG should a Transmitter and computer system prove to be glitchy.
Again, the sad truth is that all gauges come out of the SAME Factory. However one brand will be exorbitantly priced compared to another. The difference is purely that you’re paying for the branding.
