Jobs at Doc's

- When fitted properly, Doc’s proplugs help divers equalize
- Reduces “ear squeeze” caused by inability to equalize between the outer and middle ear
- Helps prevent outer ear and inner ear infection, vertigo and thermal reaction
- Without ear protection, 65% of scuba divers suffer from ear problems which keep them away from the sport (source: DAN)

Doc’s Proplugs can prevent swimmers ear, and ear pain by blocking water from entering the ears, keeping ears warm and preventing the flushing of water in and out of the ear. Ear pain and infection are caused by cold exposure and erosion of delicate skin and wax in the ear canal.

Upon descent, Proplugs prevent water from entering the ear down to 20 feet in depth. Once the diver enters greater depths, water will be allowed into the ear for equalization. Unlike other earplugs, ours includes a Scott’s valve which allows ears to equalize easily and let sound in. Our proplugs have been used by hundreds of divers for over thirty years who testify that proplugs are the earplugs for divers.

Equalization with Doc’s Proplugs: Doc’s Proplugs have also been used by divers who have trouble equalizing. Unlike other earplugs which are solid and would not be recommended for diving, Proplugs are vented to allow equalization. While the small vent allows equalization to occur it does not allow debris to enter and it prevents earwax from washing out which exposes delicate ear tissue. The Proplugs keep ears warm by storing the head’s conductive heat; the warmth provided by the plugs drastically reduces the risk of thermal shock. Due to surface tension the vented plug also reduces abrupt pressure changes from reaching the sensitive eardrum which contributes to easier equalization. Clear ears often to allow air to escape through the Proplugs vent and allow for better equalization. Proplug wearers who have trouble clearing their ears should check to make sure a lump of ear wax is not blocking the canal or butting up against the vent. If the vent is fouled by debris while descending it is best to remove the Proplug. If fouled while ascending, there is no problem because the air and water under pressure can escape around the Proplug.Hundreds of thousands of divers have attested to the benefits of Proplugs for relieving pressure in their ear during descent.


I've had a lot of trouble equalizing in the past and have often had to deal with MEB (middle ear barotrauma), characterized by nosebleeds and more when surfacing. I bought a pair of your vented proplugs and tried them out this time and was pleasantly surprised that my first dive with them was painless and very comfortable.” - Susheel J. Kurien

“As an avid technical diver, I can only say that Proplugs have allowed me to continue to enjoy my favorite hobby when a ruptured eardrum threatened to take me out of the water forever.” – Mark Zurl

“After many years of diving, I had seriously considered giving up the sport. Every single time I went on a diving trip I experienced an ear infection. Not only did the Proplugs stay put, but for the first time in 8 years, I got to spend 3 weeks on Maui diving and not being sick. I have done about 30 dives since then and not one ear infection, no sore throat, and still on the first pair of plugs.
I have absolutely no trouble equalizing and I have never had one come out! - Karen Edwards

The Proper Fit Is Important

Doc’s Proplugs work best when they are properly fitted.


- Doc’s Proplugs were used to achieve the World Freedive Record with a depth of 192 feet. (full story)

- World Champion Freediver used Proplugs to protect her ears from pain and infection and allowed her to equalize effectively.
