Shrewd, CR, CBE or Extreme Scopes (non-wrap): Sight Pin Light (SPL) Assy. Installation Instructions
1. Cut 1.5” - 2” long piece of fiber from the 24” piece supplied, depending on scope diameter. Flare one end of fiber by heating the short end
of an Allen wrench and gradually bringing it close to the fiber, without touching if possible. Repeat until the flared end of fiber is at least
1/16” or larger (.063”-.080”) in dia.
2. Cut a 5/16” (.31) or 1/4” (.25) for Shrewd Scope, piece of sheathing from 8” piece supplied.
3. Slip pre-cut piece of sheathing over 1.5” piece of flared fiber optic strand.
4. Carefully press sheathing and fiber with flared end into brass LED housing. If sheathing w/fiber does not seem tight inside brass housing,
remove sheathing and fiber from housing. Pull sheathing off fiber and slightly mash down the end going into LED brass housing.
Re-insert with fiber into brass housing. Sheathing will fit tight but still be removable if necessary.
5. Screw LED assembly with fiber into scope housing. Fiber length may need to be trimmed before actually feeding it into up or down pin or
lens hole. Check by laying fiber near pin first, if it sticks out too far past pin, trim accordingly.
6. Once length is correct, feed fiber through pin.
7. Flare this end to your preference using the heated end of an Allen wrench as recommended, w/o touching fiber (i.e. radiated heat).
8. Proceed to GEN. INSTALLATION INSTRUCTIONS, PL DX LED… Installation, Step 2.
1. If current Stainless Steel pin is being used, remove old fiber for best results. If
fiber breaks off or is very difficult to remove, install a new stainless steel pin
centered in scope, before proceeding to Step 2.
2. Place SPL with cable clamp at 1 o’clock position (see pics) & mark hole center.
3. Drill hole thru fiber guard with #29 bit , then tap for 8-32 screw as shown.
Mount cable clamp with SPL Ass’y to fiber guard using 8-32 button head screw.
4. For best results use latest (clearer) sheathing from Classic Archery Products.
5. Push sheathing into base of scope about 1/4"-3/8” and over Stainless Steel pin.
Sheathing should bottom out, (avoid moving SS Pin position).
6. Wrap sheathing around fiber guard in grooves and next to black cap/cable
clamp of SPL Assembly. Cut sheathing off 7/16”-1/2” from tip of black cap
toward SPL Assembly wires.
7. Install sheathing into SPL Assembly. Cut sheathing length until it fits snugly
into grooves of fiber guard and fits into SPL Assembly about 7/16”. Sheathing
should not quite bottom out. Remove sheathing from scope and set aside.
8. Remove SS Pin from scope & fiber from Teflon sheathing unless using other
fiber. Insert fiber into SS Pin from BOTTOM of Pin. DO NOT insert fiber from
viewing end of SS Pin –doing so will reduce brightness. Continue feeding fiber
through Stainless Steel Pin until it sticks out of viewing end of SS Pin about
1/32”. Allow fiber to hang, but be careful not to kink it.
9. Flare viewing end of fiber to desired size –see Step 1 of Competition Scope
Installation on other side of this sheet. Do not over flare fiber. If you do, pull
fiber out, trim it and re-flare. Gently pull hanging fiber so viewing end is
almost flush with Stainless Steel Pin. Feed fiber with SS Pin thru inside hole of
scope until brass sleeve of SS Pin bottoms out, align SS Pin and tighten screw.
10. Carefully slip sheathing over hanging fiber. Re-install sheathing into base of
fiber guard & over SS Pin as in Step 5. Loosen SS Pin screw if needed to get
sheathing to install, then re-align & tighten holding screw. Do not kink fiber.
If blue fiber is used and kinked at all, it must be replaced.
11. Cut fiber 3/16” longer than sheathing, and flair it according to Step 1 of Compe-
tition Scope Installation (see opposite side of sheet). This end should be flared
very large. Press sheathing into groove half way to first cotter pin location.
12. Cut longer halves of 2 brass cotter pins to match shorter halves. Slip 1 brass
cotter pin over sheathing, align with first hole. Finish pressing sheathing into
groove and slip cotter pin into hole. Tighten down cotter pin holding screw.
13. Slip 2nd cotter pin over sheathing and begin pressing sheathing into groove.
Align cotter pin with hole and simultaneously insert flared fiber end into LED
Assembly. Tighten down cotter pin screw.
14. Hold SPL and cable clamp while tightening down its button head screw.
15. Use Zip tie (see pics) to secure wires at brass. Or for best protection, cut off
~1/16” of open end of black rubber cap and press over wires and knurled end
of SPL Brass (rubber cap is too long if not cut). Proceed to Pro-Light DX SPL &
Power/Control Pack installation, Step 3.
Classic Scope w/ large groove Fiber Guard
Sight Pin Light (SPL) Assy. Fiber Installation:
PLEASE READ ALL STEPS BEFORE BEGINNING
(Especially for Blue Fiber)
CBE Scope: Sight Pin Light (SPL Assy) Installation Instructions
(For Short Fiber and/or Down-Pin set-up; See Installation Instructions Above)
1. Install SPL on scope top w/ cable clamp, 8-32 button head screw & brass washer- not shown.
2. Install tubing into scope bottom hole, if tubing fits loose, pinch slightly w/ needle nose pliers. Wrap
tubing around scope side & into LED; remove tubing from LED & cut to length, as shown. Tubing
should go into SPL ~5/32” or to about middle of plastic clamp. (see photo at right)
3. Install fiber into tubing & up into scope. Carefully arc fiber into pin, as shown.
4. Flare fiber at pin end. Carefully pull flared end of fiber flush against scope pin.
5. Cut fiber at SPL end ~3/16” longer than tubing. Flare fiber at SPL end to .060”-.080” diameter. Fiber
needs to be flush with tubing at SPL end.
6. Install tubing with flared end of fiber into SPL. (see photo at right)
7. Using wire from a twist-tie (remove plastic covering), or small zip-tie. Secure tubing to edge of scope.
Trim zip-tie or trim twisted wire and push down along tubing as shown.
8. Cut ~1/8” off of open end of the Soft Rubber Cap.
9. Secure wires along side of scope housing at windage rod with a zip tie. Secure wires were ever con-
venient, allowing slack for windage & elevation adjustment.
10 Continue to Step 3 of GEN. INSTALL. INSTRUCTIONS, PL DX SPL & Power/Control Pack Installation.
Adding an 8-32 or 10-32 tapped hole: to scope housing, fiber guard or pin sight:
1. Determine the best location for the SPL Brass. See drawing on other side of this sheet for Shrewd Scopes.
2. For aluminum scopes, pre-drill an .062 diameter starter hole.
3. Drill out the starter hole with a #29 bit for an 8-32 hole or #21 bit for a 10-32 hole.
4. Carefully tap hole to required tap size. NOTE: Many tool or hardware stores supply the #29 or #21 bit with the tap as a set.
LP Archery Products, LLC nor Pro-LIGHT DX Warranty covers a scope or sight that has been damaged by adding a
tapped hole incorrectly. Be sure that whomever adds tapped hole to scope or sight is qualified to do so correctly.
(Large groove fiber guard is latest model with an ~.090” wide groove)

Mount 8-32 SPL w/ Nylon tip using cable clamp to desired location on scope. See CBE Install Pic. Below for example. Install Adaptor using
(1) 8-32 washer at desired location. Push (twisting) .094 tubing up through opening of adaptor so ~1/16” is exposed. Run tube into 8-32 SPL
allowing just enough slack in tube to secure to side of scope w/ zip tie, cotter pin or 8-32 BHCS & washer. Cut tube as needed.
