INSTRUCTIONS FOR MODEL T7500 HI-HELIX 3D

Congratulations on your purchase of one of the lightest, most durable moveable sight on the market today. With just a little bit of care, this sight should last you for years to come. Here are the basic instructions for assembling the sight.

When you receive your sight from either your dealer or through a delivery service, your sight will come packaged in a protective black carrying case. We strongly recommend that if you need to take your sight off of the bow, you place it in this case to minimize the possibility of losing items or misplacing anything. The first step to assembly is to remove the bowplate off the extension bar and mount it to the riser of your bow using the enclosed Flat head screws. Next, you will slide the dovetail piece on the vertical base into the dovetail slot on the end of the extension bar/windage unit. You may need to loosen the socket head cap screw a turn or two to allow the above procedure to take place. It will take the 9/64 wrench on a standard allen wrench set. Once you have the base positioned approximately where you want it, tighten the screw down.

If you are going to be using a scope with this product, unscrew the threaded pin out of the brass hexagon tube. Next you insert the brass hex tube into the hexagon hole in the windage until in stops. Then you use the knurled knob and screw the tube into the windage housing until it is approximately in the center. Then you will screw your scope rod into the hexagon tube until the scope housing is up against the tube. If your scope does not line up correctly, you can use a washer or nut between the scope housing and the end of the hexagon tube. Once you get the scope rod threaded into the tube, you can use the 10/32 nut and screw it onto the back of the scope rod and continue to screw the nut until it is against the brass hexagon tube.

Now you insert the extension bar back into the bow plate and figure out how far you want to extend the vertical base from your bow. There are milled round holes in the top of the extension bar so that when you tighten the bar down, the nylon tip on the end of the knob will fit into that hole and give you the extra security of knowing that the bar will not move.

Before you can sight in, you need to get a rough idea of where your scope or the end of your pin needs to be for shooting. The best way to do this is to knock and arrow and let it rest on the arrow rest. By looking at the bow from behind (like you would be getting ready to draw) you will be able to see if you need to move the hexagonal tube left or right. To move your windage unit, you will loosen the screw on the top (front) of the sight block and turn the knurled knob to position the scope where you want. When you have your scope positioned where you want and the pin is inline (or at least real close) with your arrow, then you tighten the screw on the top (front) of the sight back down. This is also the opportunity to place your scope (if applicable) at the angle that you desire. We recommend that the scope be swiveled so that the top of the housing is tilted roughly 2 or 3 degrees away from the archer. You may have to unscrew the scope housing a little bit to achieve the angle that you desire. When you have the angle, place the 10/32 nut on the back side and tighten down.

One unique feature of this model is that you can position the vertical base as high or low, as you need to because of the dovetail piece. There is no set placement for this base, just personal preference.

If you are using a scope, you will next need to level your sight. There are a couple of different ways to accomplish this. The first one is to go to a Archery Pro shop and let the Pro level up your sight. If you are the do it yourself type, you can purchase a leveling tool that you will place on the table and then mount your sight to this tool and level your sight. You can also choose the least expensive route and purchase the Toxonics hand held leveling tool (SC-108). To use the leveling tool, you will need to remove your sight from the bow by loosening the knob and sliding the extension bar out of the bowplate. Next you will place the SC-108 flat against the side of the vertical base that is opposite of the scope. If the bubble in the scope is in the middle and the bubble in the leveling tool is in the middle, you are good to go and no adjustments need to be made. That is not usually the case. Most of the time you will need to move the sight block one way or the other to level your sight. To do this, you will need to loosen the cap screw that is on the back of the vertical base at the bottom. It has the elongated slot to allow you to move your sight left or right. This screw also takes the 9/64 wrench. Loosen the screw and move the sight block in the direction that you need to go. When both bubbles are in the middle (on the scope and the leveling tool) you can tighten the screw back down.

Third axis leveling is next. Point your sight up to the sky (your sight should look like a T). Place the SC-108 leveling tool onto the extension bar and check the bubbles. If you need to adjust this sight, you will loosen the two cap screws that are on top of the windage block. Loosen both screws about two or three turns. Adjust your sight until the bubbles are in the middle (on the scope and the leveling tool). Tighten both screws back down snugly.

When sighting in, it is recommended that you start at approximately 7 yards. This recommended because the settings are actually very close to the same as if you were at 20 yards and there is less of a risk of losing an arrow. We recommend that you use a target with the x in the middle and aim at the x so you have a starting point. Shoot your first arrow into the target. Remember to always follow the arrow. (I.e. if you miss left, move your windage left and vice versa.) While sighting in, it is best to make small adjustments and then shoot another arrow. To make adjustments, you will loosen the screw that is locking the windage unit in place, if you have decided to use this feature, and turn the knurled knob to move right or left. Continue this process until your arrow is in line with the x in the middle of the target. When this happens, it is then time to adjust for your vertical. Toxonics recommends that you position the sight block (the part with the scope or the pin in it) at the top of the vertical base. To do this, loosen the lock knob on the front of the sight and micro adjust the block to the top. Since this sight has the Hi-Helix quick lead screw in it, this should not take long. This is recommended so that you can get the full length of the base for travel. To make adjustments, loosen the cap screw on the side of the extension bar/windage unit that is in front of the numbered knob. Remember that this screw takes the 9/64 wrench. Once that screw is loosened up, slide the base up or down as needed. Tighten the screw. The same concept applies, Follow your arrow. When you are hitting the x at 7 yards, you can then step back to 20 yards and take a couple of more shots to fine tune. After you are sighted in at 20, you will have all the information you need if you are going to be using a computer generated sight tape. If not, repeat the process at 25, 30, 35 etc. for however many marks you want to have.

Congratulations, you are now ready to take your sight to the practice range and have the confidence that you have the best equipment on your bow.

To make vertical adjustments on the range, you will just need to loosen the lock knob and micro adjust the sight up or down and lock the knob back in place. To make horizontal adjustments loosen the lock knob on the bottom of the extension and micro adjust the windage left or right.
