Deep6 Eddy Fins Review
Last updated: July 2025
- Neutral buoyancy: Stays level in freshwater, aiding trim.
- Stiff blade: Offers precise control for back kicks and stability.
- Durable build: Handles regular technical training without wear.
- Leg fatigue: Stiffness can tire legs during long dives.
- Purpose-built: Best for skills-focused dives, not casual use.
Precision focused and neutrally buoyant. Probably more suited for drysuit than wetsuit, unless you want a stiff fin option.
Pros & Cons
| Pros | Cons |
|---|---|
| Neutrally buoyant in freshwater | Stiffness can lead to leg fatigue over time |
| Excellent for back kicks and precise control | Not ideal for relaxed fun dives |
| Durable and predictable performance |
Why I Chose the Eddy Fins
These were the fins I used in my GUE Fundamentals class while diving with a steel backplate and drysuit. They’re extremely stiff and offer great control for back kicks, turning, and stability in trim. I eventually switched to OMS Slipstreams for drysuit dives due to leg fatigue, but I still use the Eddy fins as backups for wetsuit dives where I want precision.
Verdict
The Deep6 Eddy is a purpose built fin that should really be used only for diving that requires a stiff fin. I don’t recommend it as a casual, all-around travel fin. Nor for individuals who struggle with stiff ankles/kicks or cramps. However, there are many individuals online who swear by them.
Would I buy it again? No

Performance in the Water
- Trim & Buoyancy: Neutrally buoyant in freshwater. Excellent trim balance with minimal ankle weight impact.
- Kick Styles: Outstanding for frog kicks, back kicks, and helicopter turns. Flutter kicks feel heavy over time.
- Comfort: Very stiff—if your ankle or leg flexibility is limited, you may feel it after longer dives.
- Control: Excellent, though not materially better than the softer OMS Slipstream
