The TLD Mount (Target Location Device) is used to support a Mini Red-Dot for acquiring targets at close to long range without reducing scope magnification. 

Once the TLD Mount and Red-Dot are mounted, simply dial your 700 yard Dope, then place scope reticle on 700 yard target and zero Red-Dot to that target.

Once zeroed, you can dial Dope and place Dot on any target from 300 to 1,000 yards and target will be in field of view in scope allowing you to change targets quickly.

The T.L.D. Mount (Target Location Device) comes in 30mm, 34mm or 35mm and attaches easily using  either a PIC Rail mounting system or Quick Detach.  See installation instructions for more information.
