Hitting the panels
Posted 20 April 2003 - 05:23 PM
My depth perception is lousy. This hasn't been an issue in trials thus far, since my dog and I have been wearing through the panels in Novice/Novice, but I would like to start driving in preparation for moving up. The problem is that at this point it's a total crapshoot whether or not I'll manage to hit the panels if they're at any distance. I'll turn the sheep too high, or too low, and I mean either really really high, or really really low. Not only would this lose points in a trial, but it stresses out my dog, as I whistle Fly all over the place trying to figure out where the panels are, and, well, it just looks really stupid.
Other than being nearsighted (but I wear contact lenses) there's nothing wrong with my eyesight. Is there anything I can do, other than get a lot more practice, or maybe a pair of yellow sunglasses?

Well I must say those glasses do help a great deal..I also am absolutely horrible at hitting panels. Some things that have helped me get what little success I have had are really looking for markers when the cross drive line is walked, and watching several runs of handlers I KNOW ususally have a good line. Also at home, I do have panels set up but I really only use them AFTER my dogs are trained. I dont like practicing courses and I dont advocate it for people straight away for the simple fact that they get too caught up in trying to hit the panels vs watching how their dog is working example: they might let the dog off with not stoping or flanking improperly just to make the panel in practice..that is a very bad habit to get into. However, if all the mechanics on your dog are going well, you as a handler do need to practice making panels (JUST DONT LET THINGS GO IF YOUR DOG MISBEHAVES!) Try doing the crossdrive with the dog not to far from you and slowly back the distance up as you get better at seeing the line...also you should continue on with the the premise that your dog should be holding a line vs just flanking where you tell him to. With you doing at a distance you can see, you can practice just calling your dogs name to pull him back on line if he starts to drift... also another thing..at a trial, when you are watching the runs, try and sight in on the sheep when they go thru the gates, see what the picture looks like..example..do they look like they are walking towards the upper or lower panel as they go thru...it is definately difficult, but with practice you can get better..Hope this helps a bit.

Not my conclusion - this is the finding in research conducted at the US Army Aeromedical Research Laboratory (USAARL). An abstract of the article follows:
"The Role of Yellow-Tinted Eye Wear in Visual Performance
William E. McLean Clarence E. Rash, Elmar T. Schmeisser & Barbara S. Reynolds
There is a persistent perception that visual performance can be improved through the wearing of yellow tinted (blue-blocking) glasses, visors, etc. A review of past studies was conducted to identify a trend in performance effects. An additional series of laboratory and field investigations was conducted to evaluate performance with color identification tasks. The general findings support the conclusion that while performance for a specific task under specific environmental conditions may be enhanced through the wearing of blue-blocking filters, blanket use of such filters would result in more tasks and conditions where performance is degraded than those where performance is enhanced."
The full article can be found in the AMEDD Journal. I can track down the web site and specific link if any are interested in reading the complete article.
Now I will duck under my desk...

Oh well. Guess I'm just screwed.

So when the lighting conditions are poor (poor contrast) amber lenses can help you see features in the field and this may help you "hit the panels".
I believe shooters also use amber colored lenses in their safety glasses; probably to increase the contrast of the clay pigeon and the sky.

Well, it sounds like a theory anyway ;-)

Part of the thing with raptors is that not only do they have ridiculously binocular vision, they also have enormous eyeballs (their eyeballs are about the same size as ours) that take up almost all the space in their heads (which is why they will never rule the world). So they get a picture that is way magnified compared to what we see at a distance (the size of the lens and retina and everything else that makes the image is relatively huge) -- the physiological equivalent, I guess, of having a telephoto lens in your head.
Another interesting bit of eyeball trivia is that all dogs, regardless of breed or body size, have eyeballs that are about the same size (according to Serpell), which explains why toy dogs often look like space aliens.

The findings showed some help blocking blue light under some conditions (fog / mist), but did not support the use of such lenses under all conditions for all tasks. It's been many months since I read the full article, but the impression it left on me is to save my money for some other purchase then yellow lenses. The study was done to determine what, if any improvement, could be made by the use of yellow-tinted eyewear becasue pilots brought the same stories to work: "Hey, shooters wear yellow lenses and say it helps them hit the target. I want yellow lenses, too."
I'll see if I can track down the full report. If I am successful I will post the link so you can make up your own minds.

Betty Levin uses binoculars on the drives...hmmm..I wonder how that would work,and are there any rules about using them?

You can get the tech article from the USAARL site - it will download faster. You will need Adobe Acrobat to view it.
Go to: http://www.usaarl.army.mil/
Select "Technical Reports" (left side of page)
Select "Search for Tech Reports", which will open a new window.
In the "Report Number" field put 2000-20 and hit the "Search" button.
That will bring up a window w/ the report abstract.
If you click on the report number (2000-20) in the upper left of that abstract, the report will open automatically. You can read it on-line, download it, or print it from this window.
Lori- Binocs? Now that is a new one on me...! Have fun at the Lynch's trial - w/ or w/o amber lenses!

The judge allowed a person who asked to use binoculars to check to see if the sheep were set. The binoculars were used by only one person to check the set...but they were not used during the run. I think the judge was using binoculars too.
BTW This was my first Open trial ever...lucky me. However, my dog did eventually find his sheep.
