If you are holding it using that handle, doesn't it look like it will be a little bit top heavy?
If you watch some videos advising on how to use pole mounts, for example, they usually suggest to have the camera upside down at the end of the pole (activate the upside down mode as well) , so it's not "top heavy" in a way that your attempts to keep it balanced it straight up won't translate into shakiness.

The above on the pole looks viable using the camera upside down...but really wont matter under water I wouldn't think. I used an X shot extension monopod for my stuff...the video that looks most shakey is the tight shots...the rig is so small it can be difficult to keep steady. I'm still satisfied for the $ I've spent.
