Finally, I've put together some low end sights for all those videographers who can't afford to spend $250 for a concentric sight. This is the same basic sight as all the other cross sight's you've seen with a few improvements...
I cover the optics with glass. This allows you to use a t-shirt or other soft cotton cloth to clean the surface of your sight. All the other cross sights on the market leave the polarizer material exposed and it is a relatively soft plastic which scratches easily. You don't have to worry about the durability of this sight... it will last for many years.
After you have mounted the sight, you may wish to change the orientation of the optics. Depending on the orientation of your installation, the pattern may not be square with your helmet. People have different tastes as well…
You may want a vertical pattern
Or you may want a diagonal pattern
These sights have a threaded retaining ring and rubber o-ring that keep the optics in place. With a small straight blade screwdriver (the ones that come with a CYPRES work great!) simply loosening the retaining ring about 1/4 turn. Then grab the entire stack of optics by placing your thumb in the middle of the glass on one side, and place your index finger in the middle of the glass on the other side. Squeeze the optics and turn them as one unit. Since there are two glass layers surrounding a custom laminated polarizer stack, you want to turn them as one unit so you don’t scratch the polarizer laminate. Turn the optic to where you want it and tighten the retaining ring back to the original position.
The shaft comes off to allow you to custom cut the shaft without endangering the optics (in the garage near the saws, you know). Once the shaft is cut to size, you should tighten the bezel down to the shaft. It would be advisable to use lock-tight (the blue one) or crazy glue to lock the threads, but this is not necessary as you should not be twisting it hard enough to unscrew the bezel during field adjustments if you are using the proper clamp.
Pricing is as follows:
Sight only - $130
1/4" - 1/4" swivel clamp + 1/4" aluminum mounting post. - Add $30.
