The fingerhole's function is to be able to use the on/off button and the zoom button if you want to, but even more important, to use the record button.
For example, you're filming some fish under water, but at the moment there are no fish around you. At that moment you're just wasting a lot of your tape, and you don't want to get the case out of the water all the time to get your camera out of the case and push the record button. So for that reason, a fingerhole would be nice.

- You can find the zoom, on/off and record buttons really close to each other, most of the times...but first, you have to check the measures of your camera. You have to determine at which position the fingerhole has to appear.

- With your pencil you can draw a small round, with a diameter 3 cm, at the place you determined, because the PVC is also 3 cm.

- With the electric drill machine, you can create the hole.

- With the file you make the hole smooth.

- Then take out the PVC and saw a piece off with, approximately 3 cm long. Afterwards you can make the edges smooth again with the file. You can try if the PVS fits in the hole you drilled in the case. There should not be much space. In fact, I hope it doesn't fit, so you can use the file to make the hole bigger bit by bit, till it fits precisely.

- Now take the glove...choose one finger you want to use. Make sure the finger is not too long, because you'll loose your feeling inside the case if the finger is too long. Use the scissor to cut one of the finger off the glove.

- Take the finger and stretch it so that you can put the end of the finger over the PVS. Make sure approximately 1cm from the finger is over the PVS now. It should be really tight now.

- Get your bicycle tire inner tube en cut 3 small slices off with a with of 0,5 cm with your scissor. Put these 3 slices around the part of the PVC where the finger is placed over. Turn all the slices 1 time so they're dubble around the PVS. It will be really tight but it should fit and will be watertight.

- To be sure it is watertight, put a little bit of silicone paste on your thumb and rub it around the PVC and the slices.

- Now you put the finger attached to the PVS through the hole. Put a lot of silicone paste on the edges where the PVC and the case meet...on the inside and outside of the case.

- Now let the silicone paste dry for a few hours...then, you have to test the housing again for watertightness!
