I've used the Divesoft DNA Analyzer for a full year as my primary tool for analyzing Nitrox fills. It has been with me across quarry dives, day boats, and coastal trips, and has proven consistently reliable. While it does require a smartphone to view readings, the app works without internet access and has never let me down. The analyzer runs on a single CR2450 coin cell battery, which has lasted through a full year of regular use without replacement.

Pros & Cons

Why I Chose Divesoft DNA Analyzer

I needed a Nitrox analyzer that was compact, durable, and easy to travel with. The Divesoft DNA stood out for its clean design, stable calibration, and small footprint. I already trusted the brand’s engineering, and I preferred the simplicity of replacing a CR2450 battery over worrying about charging cables. I chose it over screen-based models because I always have my phone with me, and I liked how little space it takes up in my kit.

Verdict

This analyzer has been a consistent part of my diving workflow. It lives in its original case with a marker for tank labeling and gets used before every Nitrox dive. I have never had to recalibrate it on a trip, and I have never seen it return a questionable value. It does exactly what I need, without taking up space or attention.

Would I buy it again? Yes. It fits how I dive, and I would choose it again without hesitation.

Who Divesoft DNA Analyzer Is Best For

This item is best suited for:

• Recreational Nitrox divers who value portability and precision
• Divers who are comfortable using a phone as part of their kit
• Traveling divers who want a simple, durable analyzer

It may not be ideal for:

• Divers who avoid using phones around dive operations
• Those who want a built-in screen and tactile controls
