Will I have bouyancy issues with my camera if I just skip the weights and get an underwater casing alone? I have a Canon PowerShot A630 camera I'd like to take diving. It really depends on how you like your housing. Remember, the housing will display a certain volume of water. So, the deeper you go, the more positively bouyant it will be. If you add no weight, then the housing will really be hard to handle at depth.
My guess is you want to set the housing up to be neutrally bouyant. Of course, sometimes it is nice to have it negatively bouyant, so you can set it down during a dive. Then again, you may want it to be positively bouyant (a bit) so it will head for the surface if you lose it. In most cases, you just want it to be neutrally bouyant, so you just have to worry about its inertia and not worry about having to fight it. yes - the camera and casing need to float without rising or falling when you let it go, else you will be pulling the camera to hold it still and then you lose your bouyancy. Although you may be able to add your own weights to the case to save monies and get a better balance as diffeernt depth will create a need for slight different weights. Remember the casing does not flex like the human body (lungs) does. |
