DeepSpot Freediving Poland – The Complete Guide
Independent guide based on Kaluna training experience
Deepspot in Mszczonów, near Warsaw, is Europe’s deepest diving pool. Its 45 m shaft, clear water and constant temperature of 32–34°C create exceptionally consistent conditions for freediving, equalization and technical depth training.
This guide explains what Deepspot is really like, who can train there, what to bring, where to stay and why Kaluna Freediving continues to use it for coached training weekends.

What Is Deepspot?
Deepspot is an indoor diving facility in Mszczonów, Poland. The pool contains a central shaft of approximately 45 metres, shallower training areas, platforms, underwater scenery and a spectator tunnel at around five metres.
It was designed for both scuba diving and freediving. Beginners can start in instructor-led sessions, while certified freedivers can use dedicated training options with a buddy or instructor.
The decisive advantage is not the depth alone. Deepspot combines meaningful training depth with warm water, excellent visibility and a weather-independent setup. This makes the facility useful for training throughout the year, including during the European winter.
Why Freedivers Train at Deepspot
Open water is essential for becoming a complete freediver, but it is not always the most efficient environment for correcting one specific problem. Waves, current, low visibility, thermoclines, boat traffic and changing weather can consume attention that should be directed at technique.
At Deepspot, the environment stays almost identical from one dive to the next. You can make a controlled attempt, receive feedback and repeat the same exercise without waiting for conditions to improve.
Efficient Repetition
Less time is lost to weather, boat logistics, surface chop or long preparation between attempts.
Immediate Feedback
Coaches can observe descents clearly, review video and adjust the next dive during the same session.
A practical advantage that is often underestimated: most freedivers can train in normal swimwear. You do not need to squeeze into a thick wetsuit before every session, and buoyancy changes are much smaller than in a conventional open-water suit.
Equalization and Technique Training
Deepspot is particularly effective for equalization training because you can focus on the technique itself rather than simultaneously managing cold water, waves, current or poor visibility.
Depending on your experience and objectives, training can focus on:
- Frenzel equalization and troubleshooting
- Mouthfill preparation, timing and refinement
- Relaxation and controlled descent speed
- Free Immersion, Constant Weight and no-fins technique
- Streamlining, body position, finning and turns
- Hangs, adaptation and structured depth progression
Repetition alone is not enough. Useful coaching identifies whether a failed dive comes from equalization mechanics, excess tension, head position, descent speed, technique or poor dive planning.
Freedivers who want to prepare before a trip can book private training with Kaluna Freediving.
Who Can Train at Deepspot?
Deepspot is not only for 40-metre freedivers. The facility offers useful training for complete beginners, recreational freedivers, course students and advanced athletes. The correct depth is determined by your certification, ability, equalization and training goal—not by the maximum depth of the pool.
First-Time Freedivers
Beginners can book an instructor-led introduction and learn breathing, relaxation, safety and basic depth procedures in the shallower areas.
Certified Freedivers
Certified divers can train with an appropriate buddy or instructor, subject to the facility’s current booking and safety requirements.
Advanced Freedivers
Experienced divers can work on Mouthfill, discipline-specific technique, hangs and preparation for deeper open-water sessions.
Safety rule: freediving must never be practised alone. Independent training at Deepspot is intended for certified freedivers using an appropriate buddy system or instructor support. Always check the current facility rules before making an independent booking.
What to Bring: Equipment and Practical Tips
Essential Items
- Swimwear and towel
- Mask or fluid goggles and nose clip
- Fins or monofin, if required for your session
- Dive computer, if you use one
- Water bottle and suitable food between sessions
- Certification and medical documents required for your booking
Wetsuit and Weights
At 32–34°C, most freedivers do not need a wetsuit. People who become cold during longer sessions may prefer a very thin thermal layer.
Avoid using your normal open-water weighting automatically. A swimsuit or thin suit changes buoyancy substantially, and any weight setup must be reassessed for the pool and the planned depth.
Rental Equipment
Equipment options are available at the facility, but sizes and availability can change. Participants in a Kaluna weekend should confirm required rental equipment before travelling rather than relying on last-minute availability.
Between Sessions
Warm water reduces thermal stress, but repeated depth work is still physically and mentally demanding. Plan enough time for hydration, food, rest, equalization review and a proper debrief instead of filling every available minute with dives.

Kaluna travel advice: for a short training weekend, a coordinated group transfer is normally far more efficient than trying to combine multiple local connections with freediving luggage.
Staying in an Underwater Room
Deepspot’s two-person underwater rooms are located approximately five metres below the surface. A panoramic window looks directly into the pool, so guests can watch freedivers and scuba divers from inside the room.
The rooms include a private bathroom, Wi-Fi, air conditioning and parking. Meals are not automatically included. Availability is limited, and room conditions or prices can change, so accommodation should be confirmed for the specific travel date.
During Kaluna training weekends, accommodation may be arranged in an underwater room or in a nearby hotel, depending on the event package, group size and availability.

Deepspot vs Open-Water Freediving
Deepspot is not better than the ocean or a lake in every respect. It solves a different training problem. The pool is excellent for repeatable technical work; open water is essential for adapting those skills to real conditions.
| Deepspot | Open Water |
|---|---|
| Warm, clear and predictable | Conditions vary with location and weather |
| Ideal for repetition and video feedback | Ideal for real-world adaptation and experience |
| No waves, current or thermocline | Teaches management of waves, current and temperature |
| Efficient equalization and technique practice | Essential preparation for ocean and lake depth diving |
The strongest training approach combines both: build or correct the skill under controlled conditions, then apply it in open water.
Deepspot or Y-40?
Both pools are worth visiting and both provide warm indoor depth training. Y-40 in Italy has a distinctive thermal-water setting and is an excellent freediving destination. For structured Kaluna group weekends, however, our recent experience has generally favoured Deepspot.
The main reason is training efficiency: Deepspot has usually given our groups more practical space, smoother coaching logistics and less waiting between focused dives. That does not make Y-40 a poor facility; it means the two pools are better suited to slightly different experiences.
Kaluna recommendation: choose Deepspot when the priority is concentrated coaching, equalization work and maximum useful training volume over a weekend. Choose Y-40 when the thermal-water experience, Italy and the overall destination are equally important.
Kaluna Freediving Deepspot Weekends
Kaluna Freediving organizes structured Deepspot weekends for freedivers who want more than an unguided pool entry. We use the facility for individual technical work, safe depth progression and concentrated coaching over several sessions.
Depending on the published event, a weekend may include:
- Several coached depth sessions
- Professional freediving safety
- Equalization and technique feedback
- Underwater photo, video and dive analysis
- Small training groups
- Accommodation and group-transfer arrangements
The objective is not simply to accumulate dives. Each session should produce useful feedback and a clear technical focus for the next attempt.
Kaluna Freediving Opinion
We have trained at Deepspot repeatedly and continue to return because it produces a high amount of useful training in a short period. The depth is attractive, but consistency is the real value.
Warm water, clear visibility and a stable setup make coaching more precise. A technical issue can be observed, discussed and retested without the environment changing between attempts. That is especially valuable for equalization, descent mechanics and confidence after a period away from depth.
Deepspot is not a substitute for natural water. It is a highly efficient training laboratory before the same skills are transferred back to the lake or ocean.
