Choosing among dive computers & instruments comes down to the console features you actually want and the condition you're prepared to accept. These two Suunto Cobra configurations share an air-integrated format, but they take different approaches: one pairs a compass and case with a lower listed price, while the other names RGBM, Nitrox, and an extra battery.
Quick verdict
At USD 119.95 versus USD 200.00, the listed-price spread is $80.05. The Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested is the lower-cost route, but its Used condition and "Untested" wording are important limitations. The Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox with Extra Battery costs more and is listed as New, with a more detailed feature set.
Choose the first Cobra when the lower price and compass-console setup are the priority. Choose the second when the New condition, named dive modes, and extra battery better match your plans.

Where each Cobra wins
Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested

This configuration wins for a shopper who specifically wants a compass console and a case named with the dive computer. It also has the lower listed price, making the decision straightforward for buyers whose main constraint is the purchase amount rather than a broader feature package.
Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox with Extra Battery

The second configuration wins for shoppers drawn to its detailed display and alert features. Its description names a bright electroluminescent backlight plus audible alarms for ascent rate, depth limits, and safety stops. Those are concrete reasons to prefer its feature mix, separate from the compass-and-case emphasis of the first Cobra.
Product notes
Suunto Cobra Air Integrated Scuba Dive Computer Compass Console
The first Cobra is easiest to understand as a compass-oriented console choice. Its title names an air-integrated scuba dive computer, a compass console, and a case, giving it a concrete reason to choose when navigation is central to your gear brief. The key limitation is equally clear: the condition is Used, and the title says "Untested." That wording does not establish operating performance, so it matters to anyone who wants a known working result. Select this Cobra when the named compass-and-case configuration outweighs that limitation. The other Cobra is the better match when New condition and a more extensively described set of dive modes are the deciding details.
Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox
The second Cobra suits a different brief. Its title names RGBM, Nitrox, and an extra battery, while the description specifies Air, Nitrox from 21% to 50%, and Gauge modes, along with real-time tank-pressure monitoring. Those details give it a concrete reason to choose when mode flexibility and the included battery matter. The main limitation is the $80.05 spread over the first Cobra, which makes the feature decision more consequential. The New condition is another clear distinction, but it does not by itself determine whether this configuration fits your diving plans. Choose this Cobra when its named modes and extras matter more than keeping the purchase amount lower.
Final choice by use case
For a compass-console and case brief, choose Suunto Cobra Air Integrated Scuba Dive Computer Compass Console w/ Case Untested, provided the Used and Untested wording fits your expectations. For a New configuration centered on RGBM, Nitrox, and an extra battery, choose Suunto Cobra Dive Computer Air Integrated Console RGBM Nitrox with Extra Battery. The decision is ultimately accessory focus and lower price versus a more detailed mode-and-feature package.
