Protect Your Underwater Camera from Damage Caused by Leaks & Condensation

What are Leak Insure Sachets & How do they work?


What are Leak Insure Sachets

Leak Insure sachets contain highly absorbent granules that can hold 400 times their own weight in freshwater.

The granules we use are fast acting, ideal for soaking up leaks quickly. The sachet has been designed to hold approximately 40ml of water without the sachet splitting. However if the sachet does split it should not have any detrimental affect on you camera.

Other uses:

Leak Insure sachets not only protect your camera if your underwater case leaks, they also act as an excellent desiccant, even better than silica gel.

  1. During your dive the Leak Insure sachets will reduce fogging caused by condensation in your underwater case.
  2. Keep a sachet in your underwater camera housing when not in use to make sure it stays dry
  3. Prevents damage and corrosion from harming your camera equipment
  4. Help protect lens and electronics from humidity during a dive or while in storage.


A major problem that underwater photographers have to contend with is condensation on the inside of the camera housing.

Cameras and strobes create heat during use, this heat warms the air inside the housing. When this warm air meets the cold housing, condensation is formed on the walls of the camera housing.

To avoid this, set up your camera in an air-conditioned room, or a place that has little moisture in the air.

Another thing you can do is insert a Leak Insure sachet or two inside the camera housing at a place where they are not blocking any buttons or the lens and flash (we recommend underneath the camera). Make sure the sachet does not interfere with the o-ring seal.

The Leak Insure sachets have been design to fit most underwater camera housings or other underwater equipment.

It goes without saying that you should not rely on the sachets alone, you should always take every precaution to prevent leaks in the first place. Take a look at our advice page for tips on how to look after your underwater camera and case.

Step by Step

  1. Work out the best place to put the Leak Insure Sachet. The sachet needs to be placed at the lowest part of the housing when the camera is not being used.If your camera is positively buoyant this is likely to be near where the lanyard/strap attaches to your camera housing.If your camera housing is negatively buoyant, then the sachet should be placed directly opposite the point where the lanyard/strap attaches to your camera housing.The granules in the sachet will only soak up water while they can expand, so where you place the sachet needs to have enough space to allow optimal expansionpositions
  2. Take a Leak Insure sachet and make sure the granules are loose (if not break them up) and spread across the sachet. Shake of any loose dust or fibres.
  3. Place the sachet in between the camera and housing ensuring it is flat.
  4. Close your housing carefully to ensure the sachet does not infringe the O ring.Note: There is no reason why you can’t use more than one sachet. In fact we recommend it in larger underwater housing for video or SLR cameras. 

Better to be safe than sorry!
