I have checked out this rangefinder online and seen the video.  I read through the instructions and it seems like a great item.  I'm going to get one and I'll let you know how it works.

I have not seen it.  Do you have a link?

If it's like a peep sight, does that mean you have to draw back to range the critter?  If so, that would be a pain in the butt having to draw back numerous times until it's in range.

I'b be interested to see if you get one.

Vermonster, go to deadonrangefinder.com and watch the video and check out the instructions.  The Sportsmans Guide has it for $19.97.  Hope this helps, check it out.

The concept looks good however the system will never be quite dead on as the name states.  It is calibrated of the size of the animal’s body.  Even when you are hunting the same species they are not all the same size.  A four year old whitetail buck does not have the same body as a seven or eight year old buck. 

 I don’t think it would be something I would strap to my sight.  The main reason is that the rangefinder is calibrated for one species of animal at a time.  Every time you change the animal you are after you have to change the rangefinder.  For someone like me who can hunt up to 4 different animals in the same week (Mule Deer, Elk, Bear and Coyote) it wouldn’t be “Dead on.” 

If you only hunt one species or you are willing to change the rangefinder for each hunt then this would be an effective and inexpensive range finder. Just remember that it is not absolute and you will have to practice with it A LOT to test the right and left limits of its abilities.

The Dead-On Rangefinder was previewed by some of the members of the North American Hunting Club and the general concensus was that it is a great product.

i tried getting a patent on that 15 years ago and the price was $25,000 just for the intitial start up through inventions network and of course they got the scetches and drawings. Sometimes an education does cost you money. If this particular product did come from the inventions network staff then they should atleast send me one I would think. I'm not disgruntal about it I have two more products in development now and a lot smarter about it's introduced. I still have the original model I built for my self for hunting. It worked okay but it's not as perfect as one would think especially if your looking at a 600lb bull elk versus a 900lb bull elk. But it does work + or - 5yards and most bows are fast enough to handle that calculation up to 35 yards. Good luck.
