  • You might want to try calling the UW camera shops or you probably cant get them from amazon.

  • Alternatively if you can't find ready dessicant packs, you can get some cheap empty tea bags (daiso and most supermarket sell them) and a bottle of silicon gel (one big bottle for probably <= $4) and fill the bags yourself.

    For me I just cut the bags to size, fill it and place it in the housing. Works for me so far. Just don't be greedy and overfill the bag and be careful not to have the bag or gel stuck in the edge of your housing. :)

  • Thanks for all your suggestions and feedback.I had called canon asking dem the price for the weight is $59,4
    pieces of weights.After some thinking if i put the weights on my marine housing,what if i accidentally drop it?It
    will sink because it has become negative buoyancy.Quite confused haha sorry i am a contradicting guy!  :o

    For the desiccant packs just to share. I tried squeezing one pack into mine casing,before i knew it, there are water droplets in mine camera! I guess that i accidentally close with the desiccant pack at the edge of the housing, luckily my camera was fine,or maybe i put too much silicon gel on mine o-ring that what the dive master told me.:'(

  • An idea to try as an alternative (recommended to me rather than my advice).

    You get moisture inside the housing which condenses when you dive due to humid air and change in temperature.

    Immediately before closing the housing blow air through it from your tank then shut quickly so hopefully it is the tank air in the housing.  Ok sounds a bit daft but air in the tank is basically zero humidity so no water to condense so no fogging.

    As I said this is not first hand info but could give it a try.

    I won't advise doing this for following reasons:
    1. you may accidentally turn the valve too much and get a strong jet of air.
    2. risk getting particulars blown around and trap on the o-ring.
    3. better to setup in a dry and comfortable place then rushing on the boat.

    Fair enough points but I did give the disclaimer it wasn't first hand info.  Most people use the tank to get rid of moisture from their reg cover, I know at least one instructor who advises against this as well (use somebody elses towel.....).  I guess it comes down to common sense, you aren't going to have it fully open or hold the housing in front of the tank before you have a sensible airflow first (i.e. avoid point 1).

    As for cost, for a polycarbonate housing for a point and shoot it is a few hundred bucks, for a professional set up with additional bells and whistles for an slr it will be a few thousand.  Scubacam is probably the place to look for the latter.
