Nikon Sport Optics has come out with set of new riflescopes with a Distant Lock function located in the first focal plane that allows for scale and distance proportion to be maintained on a target across the entire zoom range.
With the new BDC Distance Lock function that keeps everything in the first focal plane, the aiming points provided by the Nikon’s Spot On ballistic application will be the same, regardless of what magnification the riflescope is set at, the company said in a recent statement. That’s because with a first focal plane riflescope, the reticle changes in size as one zooms to higher or lower magnifications.
Nikon’s Spot On program permits riflemen to input their shooting conditions and ballistic information in order to find the exact point of aim on Nikon’s BDC reticles (with unique circles and hash marks) for whatever distance they are shooting. It also provides users with exact aiming points on the BDC reticle for any load or ammunition at a specified range.
Nikon’s previous riflescopes have all been in the second focal plane, the company said. For Spot On users that meant the aiming points remained specific to one magnification – typically the highest power. The Spot On program also provides users with exact aiming points on the BDC reticle for any load or ammunition at a specified range.
