Lloyd90 Posted October 30, 2016 Report Share Posted October 30, 2016 Does anyone know which ones are the most basic and which ones go up to the higher spec ? E.g. - looking at an Artemis (not sure where that comes in their range). Any idea of their worth second hand ? Spotted a 3-12x50 with illuminated dot just wondering what's a good deal and what would be over paying ? Thanks lads Quote Link to comment Share on other sites More sharing options...
Bewsher500 Posted October 30, 2016 Report Share Posted October 30, 2016 £3-350 for 3-12x50 £350-400 for an IR version cracking scopes most zoom models come in 2nd focal plane (i.e. reticule appears to get bigger as target gets bigger under zoom, reticule and target stay same size in relation to each other through the zoom range) Quote Link to comment Share on other sites More sharing options...
Bewsher500 Posted October 30, 2016 Report Share Posted October 30, 2016 ah yes always screw that up! What is the difference between a front focal plane (1st focal plane) reticle and a rear focal plane (2nd focal plane) reticle? A rear focal plane reticle design creates a situation where the apparent size of the reticle does not change as the magnification is adjusted. In these scopes, the amount of target area covered by the reticle is inversely proportional to magnification; as the magnification is increased, the amount of target area covered by the reticle is decreased. This can be seen by looking through a variable magnification scope and increasing the magnification setting. As the power is increased, the apparent size of the target is increased, but the reticle appears to remain the same size; the result is that the reticle covers less of the target when the magnification is increased. Rear Focal Plane Reticles Many hunting scopes are designed with rear focal plane reticles. This allows the reticle to appear bolder and heavier when set to low magnification, but appear thinner and more precise when set to high magnification. Most hunters set variable magnification scopes to a mid-level magnification for general carry situations, reducing magnification in low-light or heavy cover situations, and increasing magnification for longer, more precise shooting solutions. Rear focal plane designs allow the reticle to appear bolder in low light, making them easy to see and faster to acquire when the light is fading. This same property is advantageous in situations where heavy cover may be encountered, allowing easy differentiation between the reticle and vegetation. If a longer distance shot is to be taken, the magnification can be increased, creating a situation where the reticle covers less of the target, allowing the user to be more precise. Front Focal Plane Reticles Mil and MOA based reticles are based on a specific subtension and require exact feature spacing to be accurate. If this type of reticle is used in a rear focal plane design, the scope must be used on a single, specific magnification (typically high power). Placing this type of reticle in a front focal plane design allows the operator to use the scope on any magnification while retaining the exact spacing of the reticle features.

Lloyd90 Posted October 30, 2016 Author Report Share Posted October 30, 2016 Do you think one is worth £365 plus postage , boxed in decent condition ? Or is that over paying? Quote Link to comment Share on other sites More sharing options...
Bewsher500 Posted October 31, 2016 Report Share Posted October 31, 2016 all day I have a non IR for sale at £325! Quote Link to comment Share on other sites More sharing options...
