Traditional snorkels

Traditional snorkels also know as 'J' snorkels, are a common choice for free divers and spear fisherman. These snorkels are manufactured to prevent drag which is turn gives you optimum agility whilst you are in the water- they don't have any fancy features and are recommended for more advanced snorkelers.

For example, these snorkels are ideal for people who want to reach further depths without having to use proper diving equipment. 

If you go under the water, the tube fills up with water and will need to be purged once you reach the surface- this is ideal for free divers and spear fisherman because they take one deep breath and are then able to go beneath the water. 

They don't include any safety features such as a float valve, in saying this they are the most affordable snorkel but are not great for beginners due the the J-tube not being flexible.

Semi-dry snorkels are considered a mix between traditional and dry snorkels. They do not keep all of the water out of the tube but they prevent water from getting in when not fully submerged- if you are fully submerged it is likely the tube will fill with water.

There are various features that direct the water away from the tube including purge valves, flexible tubes and splash guards which can be extremely helpful when trying the prevent water from getting in.

They are compact and more simple to use than dry snorkels which is why they are a popular choice for many people. Scuba divers are fond of semi-dry snorkels because it allows them to save their oxygen whilst on the surface.

They also feature a splash guard which prevents water or waves from getting into your snorkel when you are on the surface- as well as this they are flexible which means you can adjust the snorkel depending on your preference.
