i was looking at a scope for my 10/22, and in all the descriptions that say something like: 3-9x40, 6x42, 3-9x50..etc. So i was just wondering what all these measurements mean and what number is best/better.

So would this be a good deal?

generally the power of the scope is listed first such as 3x9 is 3 power magnification to 9 power maginfication meaning the scope can be changed from 3 power to 4 to 5 to6 etc. the second number is the objective diameter of the scope meaning the front of the scopes diameter 40mm is pretty standard the larger the diameter such as 50mm require higher mounts and may be less comfortable to shoot as it needs a different cheek weld( where your cheek touches the stock when sighting thru the scope) larger diameters collect more light providing a brighter view/picture in low light conditions such as early morning and late evening. on a 10/22 being 22 caliber usually shots are 50yds with 100 yds being far for a 22 rimfire lso i forgot to add when one number is listed first it is a fixed power scope meaning that the magnification can not be changed(your ex. of 9x40 is a 9 power fixed, 3-9x50 is a 3power to 9 power variable magnification. also the higher magnification the less area you will see thru the scope and you will notice the crosshairs moving around the target are more pronounced. i know this is alot of info to throw at you hope it helps, target shooting off a benchrest a higher magnification is good, hunting a variable is good, generally for hunting a quality 3-9x40mm is a great all round choice. some have mentioned paralex adjustment which is the sight clears at varying distances so that it is not blurred by heat waves and magnification(basically a focus) for a 10/22 like others have said a 40mm with magnifications for small game hunting and target shooting a 6-18x40mm such as those from BSA or Konus are good not high priced scopes. a 10/22 doesnt generate much recoil so the scope with best clarity you can afford and magnification that meets your needs for targets or game. magnification is 1 times over normal 20/20 eye sight such as 9 power is 9 times magnified what you a person can see. look thru the scope at store take outside if possible check for clear view at different powers of magnification looking at objects at various distances, check for blurring around the edges of the sight picture, the higher the price usually means better optic lenses for better clarity. have a price range a look thru as many scopes within that range as can. BSA and Konus usually are $100-$200 dollars depending on features and power,

First 2 numers are the magnification..... 3 X 9 would mean the scope will magnify 3 times up to 9 times..... and the last number is the size of the large lens that lets the light in, the larger the better, the more light the better the picture you will see through the lens, go with a 40 or 50 millimeter so a good scope would be a 3 X 9 X 40 ..... thats a very common scope for deer hunting.....

Scope distance measurements?

THe numbers before the x are the magnifications. So a 3-9 would have an adjustment to be able to magnify from 3 times to 9 times.

The number after the x is the size of the optic you look into. So you've got a 40mm lens.

Generally, a higher magnification and a higher lens size will be more expensive, and found on a higher-end scope. But your 3-9x40 will pretty much be your do-it-all scope.

A 50mm scope is a little large for a 10/22.
Consider 30mm to 40mm range.
10/22's are sweet for target and small game. I use one to target shoot at 100 yards. Yea I know 50 yards is typical but I like distance. Anyway for 100 yards I use up to 18 power sometimes. Yes it has a paralax adjustment.
Last year I used it for squirrel hunting. Head shots out to 67 yards. It's equipped with a bipod.

Any microprocessor with an ADC (Analogue to Digital Converter) can be used. It takes the place of a voltmeter (multimeter) and measures the voltage from the sensor, which is proportional to distance. There are only 3 connections, +5V, common (GND) and the analogue voltage output (Vo). The link below is for the data sheet of one example. You need to find the data sheet for the device you are using if it isn't this one. As you will see in figure 3 the sensor produces a voltage proportional to distance, but there are two separate distances for each voltage. The output increases to about 2.75V at distances to 15cm, then reduces to 0.5V at around 130cm. To use this you need to know whether it is more or less than 15cm. This can be determined by: a) Knowing that it is not possible to be more than 15cm, so use the first part of the voltage scale (rising voltage for increased distance). While fig. 3 indicates this is possible, it may pay to check with a voltmeter first. b) Knowing that it is not possible to be less than 15cm so use the second part of the voltage curve, falling voltage with increasing distance. In this device specification, the range is quoted as greater than 20cm to avoid the confusion. The second link suggests mounting the sensor at the back of a robot vehicle so it cannot be closer than 20cm. Up to you. c) Move the sensor relative to the object and compare readings. The distance reading changes if the sensor is moved, so the direction of movement and the direction of voltage change indicates whether it is more or less than 15cm. Of course if the sensor indicates it is very near 15cm then the result will be indeterminate so call it 15cm. The readings update about 25 times every second so this needs to be considered in taking readings. Also the first reading is valid only after the power is valid for more than 53ms. The second link has more details about operation. The LED is reflected back to a CCD array (a one line infra red camera) so that the angle of the reflected beam can be determined, and so the distance of the object determined by trigonometry calculation. If you want to view the beam a normal digital still or video camera using a CCD camera can usually see this (reflecting off a surface) as a false colour (violet on my camera). It is beyond the scope of an answer here to describe how to program for this. It is probably easier with off the shelf boards using an inbuilt ADC and software drivers like the Arduino, Basic Stamp, Maximite, Picaxe etc.

for example the 3-9x40 is that it is a variable power scope. 3 to 9 power the 40 is the diameter of the front lens, which gives you the field of view, the second is a fixed power scope. 6 power and a 42mm lens, and the same for the last one as the first one.... I hope that helped a little

P4 is a type of reticle not a type of scope.
