Gadgets - DPV's
For those of you who don't know, a DPV is a Dive Propulsion Vehicle. More commonly known as a scooter. I really want one. But the one that I want is out of my price range for now. That, and I don't really know what I would do with it once I got it.
Anyways, this is a video of what diving with a scooter should look like.
This is a video of some guy trying to develop a new scooter. Its a little sad.
Somethings just should be done. In this case, it is the scuba diving cat and dog. The owner of the cat wanted to combine his love of his animal with his love of scuba diving. To do this he put together a helmet, small tank, and regs for this to happen.
My favorite part of this video is when the owner says, "She just hangs there and expects me to do the driving." Thats because the cat is freaked out of its mind and doesn't want to be there. It is almost frozen stiff.
Once in a while I spend some time at the bottom of the pool just to relax. If I get really bored then I start blowing bubble rings. Now, I am not bad a blowing bubble rings. But after I saw this video, I knew I need a lot more practice before I am great.
The really neat stuff happens in the last minute of the video.
Leaving the water can sometimes be a lot harder the getting in. The easiest entry is always the safest and easiest to do based on the situation. The exit can be limited based on the conditions that are presented. Make sure that before you enter the water you know how you are going to get out.
I stumbled upon this video and think that it provides a good example of 1) and exit I never want to have to do, and 2) a guy who might not realize how to get out of the water. I would have recommended he take off his fins.
Accidents are something that happen that are not intentional. In the world of scuba diving, this can lead to people getting hurt by the bends or dropping and tank on their foot and breaking some bones. No matter what we do, accidents will happen in the scuba industry.
Stupidity happens also. Every year people die or have near misses not because they were venturing a little beyond their limits, or standards, or just good practices, but because they were going way beyond them. Check this story out. A scuba diver decides to go into a wreck. Looses visibility due to stirring up silt inside and gets lost. Thanks to his buddy and another dive boat. They manage to get him out after an hour. If you have never been wreck diving, take a course they teach you how to prepare for that or at least, what you shouldn't be doing.
Basically, when scuba diving, use a little common sense and if you aren't sure, don't do it.
This has been a summer where I have had a lot of stuff going on and haven't had a lot of time to scuba dive. This past weekend I had the chance to go down to Hatteras, North Carolina and do some wreck diving. I would have to say wreck diving is one of my favorite things to do. Not only do you get to see lots of fish life but you also get to see man made structures that have been sunk. Its interesting to see what the ocean does to a ship even after a couple of months under water.
On this past trip I had the opportunity to do some underwater video work for a couple of minutes. I have to say, after my brief experience I am not a fan of it. I think its neat that you can share your experience underwater with other people but its too much effort for me. I think I will stick with still photography.
Below is a video of me on the wreck of the Dixie Arrow. Behind me is a school of Atlantic spade fish (Chaetodipterus faber).Supposedly a good fish to eat but I have never tried. Enjoy the video.
