Equipment required for dolphin swim

Ease of swimming is definitely different by choosing equipment that suits your physical strength and level.

Our shop specializes in dolphin swimming and skin diving.
Our staff who are well versed in equipment actually try and sell only the best equipment, so please use it with confidence.

We will also answer your questions about equipment selection.


1. The minimum requirements for dolphin swimming areunderwater mask, snorkel and fins3-piece set of

2.for wearing finsbootsormarine socks

3.Anti-fog mask is also required. (Anti-fogging with saliva is prohibited to prevent corona infection)

Four.wetsuitis worn for heat retention and buoyancy. (alternative to life jackets)

5. In the summer when the water temperature is hightapper(wet suit upper body only) etc. can also be substituted.

6. Avoid exposing your skin as much as possible to protect your body from jellyfish damage, sunburn, and injuries.

Jellyfish prevention cream/sunscreen

​◆ There are jellyfish in the sea regardless of the season.

Not only does it hurt when you get stung, but if it is highly toxic, you may get numbness and difficulty breathing, and you may be sent to the hospital.

Even in summer, avoid exposing your skin as much as possible, and apply anti-jellyfish cream to areas where skin is exposed, such as your face.

It minimizes damage in the unlikely event that you are stung.

​◆ Dolphin swims are exposed to the sun for about two hours.

Be sure to wear sunscreen, especially in the summer when the UV rays are strong.

Choose eco-friendly products

Harmful to coral and marine life that is regulated at overseas resortsDo not use products containing UV absorbersis.

All jellyfish prevention creams and sunscreens sold at our store are eco-friendly products that do not contain harmful ingredients.

There are many types of underwater masks, but they differ in size, material and shape of the part that touches the face.

If it does not fit your face, water will easily enter and it will be difficult to use, so be careful when purchasing.

Choose a silicone material for the part that touches your face.
​ We recommend a lens with a small inner volume and a short distance between the face and the lens because it has a wide field of view and is easy to clear the mask.

Choose a snorkel that is easy to hold and easy to clear when water comes in.

 GULL Layla Stable(for women)canal stable(for men) is recommended.

Cheap ones are fine, but those with a valve at the top to prevent water from entering are only for playing on the surface of the water.It cannot be used for dolphin swimming or skin diving as there is a risk of suffocation when diving underwater.

It is important to choose fins that match your leg strength, swimming ability, and level.
We recommend the full-foot type, which is not a strap type, and is made of rubber.
Plastic fins and diving fins are not recommended as they make it difficult to swim on the surface and make you tired.


GULL Emden: small fins for beginners

Gull Mew: Best-selling fins that can be used by everyone from beginners to advanced users!

GULL Warp Fin: For intermediate to advanced students who have graduated from MU.
​ *Super Mew is for scuba diving and difficult to use for dolphin swimming.

Gull Barracuda: The world's highest grade rubber fin boasting excellent propulsion and ease of use for intermediate to advanced users!

* Many carbon fins and plastic fins for free diving such as leader fins lack repulsive force, making it difficult to turn and not effective for small turns, so we do not recommend them for dolphin swimming. Also, fins with sharp ends may inadvertently injure dolphins or people around them, so please fully understand the characteristics of the fins before using them.

Wetsuits play an important role in retaining heat and ensuring buoyancy. (It will replace the life jacket when I say yes)

Depending on the material of the fabric, the price may be on the low side, but high-quality fabrics have the advantage of being warm and elastic and easy to move around in. There is a marked difference in heat retention and mobility between ready-made sizes and custom-made ones that are made to fit your measurements.

When purchasing, please consult us to choose a solid one.

For skin diving in the summer when the water temperature is high or at a resortTupperware (jacket type), which is only for the upper body, is fine.

Weight when wearing a wet suit (weight)is required.

The amount of weight varies from person to person, so be sure to keep track of it during practice.
