Hi, Helen _liu

I have a manual for this telescope.Perhaps I can e-mail to you?

Neither can I see anything.The instructions are totally useless and the drawing is a sketch with no explanation about how to erect it or use it properly. Also number 17 doesn't exist.I give up.

Try looking in UK photo or birdwatching magazines - usually some ads for repairers.

You can use USB external CD reader or download those software from Internet

I Think Guide Gear is Cabela's house brand.Usually Cabelas is very helpful on the phone.Try 800-237-4444, or www.cabelas.com.Good Luck and Good Hunting

A 20 MOA scope base may be if assistance. The built in 20 MOA of elevation will allow you additional adjustment.

I use a strap wrench for such tasks.

If you can move it, you should be able to unscrew it. If you can't us a strap wrench. It has worked for me in the past.

The IR Rangefinding Reticle is based on the military reticle that ranges tanks, believe it or not, front to back--whatever line the tank fits between will give the range to it...but the reticle has been adapted for use in some riflescopes. Trying to define the math behind rangefinding and downrange zeroing with multi-stadia reticles is complicated and takes some study to fully grasp the concepts, which is why I have a constantly available on-line article, entitled, "Tactical Ballistic and Ranging Reticle Analysis," right here-- http://specialtypistols.infopop.cc/Reticle_Ranging___App.pdf

Most models, the battery is located within the knob switch that illuminates the reticle, and can be accessed by removing the screw cap/insert of that knob.
Good luck
