    Bow-B-LASTTGT-yds-f, will read degree of angle but reads actual yardage to target --- not angle compensated.

    My >150 is not showing and still no range

  • BC Hunter Dec 14, 2008

    I used to get readings by clearing fields, holding power and mode for >1 sec but now I get no readings on any settings. Very frustrating product given the amount I paid for it.

    My RX-II worked great for a while, that is after I sent the first one back because it did not work at all. Anyway, It would range anything no matter how small but now only large and short range, under 60 yards. Please help.

I had the same problem, rangefinder would work only sometimes and only at short distances. Called customer support and was ready to send it in. Tech guy told me to turn off "First Target" ( or "last target") and turn on"LOS" (line of sight). Range finder now works perfectly at all distances. Apparently the first target feature doesnt work properly.

    I have been having trouble with distance since I bought this thing 2 years ago. Sometimes (1-5% of the time) it would give me distance, and other times nothing. I thought I was doing something wrong. I turned off the "First Target" and turned on LOS as instructed. That did it !
    I paid too much for the unit to just toss it asside and buy another. Very glad I went to this site.

I had the same problem and I just solved it!
On mine the greater than 150 symbol was showing and it wouldnt shut off, so on this site there is a solution, scroll around til the greater than 150 is flashing then hit the power butyton twice this will turn it off.

I compete in 3d archery so I bought a new rangefinder 2 days ago and it reads 19.2 yards at exactly 20 yards is there a way to adjust it to read properly?

Page 5 of the manual states: RANGING ACCURACY The ranging accuracy of the Scout™1000 is plus or minus one yard / meter under most circumstances. The maximum range of the instrument depends on the reflectivity of the target. The maximum distance for most objects is 650 yards / 594 meters while for highly reflective objects the maximum is 1000 yards / 914 meters. Note: You will get both longer and shorter maximum distances depending on the reflective properties of the particular target and the environmental conditions at the time the distance of an object is being measured. The color, surface finish, size and shape of the target all affect reflectivity and range. The brighter the color, the longer the range. White is highly reflective, for example, and allows longer ranges than the color black, which is the least reflective color. A shiny finish provides more range than a dull one. A small target is more difficult to range than a larger target. The angle to the target also has an effect. Shooting to a target at a 90 degree angle (where the target surface is perpendicular to the flight path of the emitted energy pulses) provides good range while a steep angle on the other hand, provides limited ranging. In addition, lighting conditions (e.g. the amount of sunlight) will affect the ranging capabilities of the unit. The less light (e.g. overcast skies) the farther the unit's maximum range will be. Conversely, very sunny days will decrease the unit's maximum range.

The difference you are experiencing (20-19.2=.8 yards) is within the device ranging accuracy of 1 yard, and is in fact an error of only 4%. That is pretty accurate

In case you have lost your manual, you can download from here:

Good luck with your device.

Simple tips on becoming a better archer

a few simple tips you can use for shooting your bow and to improve your arrow grouping . first it starts out with a good stance your feet should be shoulders with apart but not over spread will want to face 90 degrees to either the left or the right of the target depending on your shooting hand .second your draw ,when you draw your bow the bowstring should sit right below the far outside corner of your eye..thirdly calming your self take a few deep breaths and hold your last breath till your ready to shoot and settle your pins (sights) on your target remember to use the right pin for the right distance.. fourthly remember not to drop the bow when you release the arrow.i dont mean actually dropping the bow on the ground but lowering your extended arm holding the bow forward to quickly before the arrow has time to release .dropping the bow can and will cause your arrows to drop too ...shooting your bow at longer distance will tighten up your arrow grouping at closer distances

Unless the last occupant registered your Master Lock 5401d combination at and can assist you to recover the combination, then you can only try every possible combination.

How do you use the range finder on your

You have to sight it in and then insert the ring for the specific ammunition and distance you are using. From then point on, you can dial in the distance and the cross hairs will be right on.
It isn't an actual range finder, it's a bullet drop compensator.

How do you zero a simmons atec 512101, I dont have a manual, or any instructions... My first scope

Hi :)

In order to familiarize yourself with shooting please go here

I stumbled across this software a month ago as an avid shooter enthusiast. I havent had the chance to fire more than 100 rounds before i touched this and most were iron sights. now i have the math to shoot any bullet in any condition upto 2000 yards :) practically military level training but not quite.

Take the training that is provided and go through it a couple of times there are a few key things to remember

when you first start go to the training range **this range is standard humidity, temperature, elevation, and barometric pressure. This means that all you have to account for is range and wind this is where to start.

1)range the target. see below for details. best to work in yards as sierra is yards too.
IMPORTANT remember if you scope in to 20x to divide your mil dot reading by 2 before your divide the inches x 27.778 or inches x 25.4? this wil give you accurate range (lol get a laser range finder for RL :)

2) Elevation - if your range is 1530yards between 35.6 moa @ 1500 and 36.2 moa @ 1550. use a calculator to determine where your range lies (sierra can be asked when producing a range card to have a set increment if set to the exact range then exact values are given :)

so 36.2 - 35.6 = 0.6 30/50 = 60% to get this divide the range in yards inbetween the increments by the increment value IE in a 100 yard increment it would differ

once you have your elevation dial it in. rounding to the closest 1/4 min of angle.

3) Windage - Windage is a little different in the windage collumn its given in inches of drift per 1 mph wind (if your having trouble with wind take the shot first hit the target read in the bottom wind speed and then calculate that windspeed and get the math first)(use this for range to infact before you delve to far into ranging ( makes for faster learning and can be written of a laser range finder and wind speed measurement accessory which 99% of shooters use now adays unless your some vet or 10000 round pro :S not thier yet)

so take your inches of drift lets jsut say i used the same method to determine the exact inches of drift between the two given (most ranges arent exactly on) and my inches per mph is 3.2 w a 10 mp wind

this is 3.2 x 10 = 32 inches of wind drift total. to conver that to rifle clicks you might remember that 1 MOA is = 1.047 inches @ 100 yards or 1.512.. @ 100 meters that means for every 1 moa you adjust your windage your bullet will travel 1.047 inches for every hundread yards the target is away

FIRST take range 1530 yards and divide by 100 yards to get 15.3 x 1.047 = MOA of windage ON THIS SHOT which happens to be 16.0191 that means for every 1 moa i adjust into the wind it will move 16.0191" per 1 moa i adjust.

Since we know that the wind will blow it 32 inches off target you divide 32 by your Inches per moa 16.0191 to get your MOA windage adjustment of 1.9976... which is rounded to the closest click of your scope (probably 1/4 min maybe 1 min you need to check how many click between the big lines on the gun.

Once you know all this stuff zeroing becomes a matter of how high you gun is over at a certain know distance. :) Sierra has that too :S


1) Targets height in inches x 27.778 / Mil Dot Reading = Range in Yards

This is where you need to start when taking a shot. The range is the most important factor as it is what the rest of the measurements are based off of. TIP invest in some evironmental accessories something that measure wind speed and direction and barrel, Temperature, Humidity, and get Barometric Pressure.

2) Your "cheat sheet" or "range card" needs to be set up accurately, there is alot of software out there that can do this for you with accurate measurements of your environment (once you get past the math of the shooting it becomes your ability to measure your evironment that makes the shots).

I use Sierra Infinity v6 Ballistics Software :) Found here

its incredibly complicated math that i havent been able to unearth without taking a 600 dollar sniper course, to determine your own range cards in varying environments (humidity and temperature vary from day to day and wil throw your bullets off over 1000 yards)

use this software before you go to the range or as you set up to print yourself the daily range card
then just use the range card and your calcualtor to hit any target you want. youll be able if you bring your laptop or they are shooting a similar load to advise others on how to zero it in :)

3) Your going to need to get some specifics of your firearm and load. the bullet is the most finickey of variables ranging greatly from grain to grain in the same caliber. These data are your bullets Feet per second(this helps determine bullet flight time which decides on bullet drop) and Ballistics Coefficient (a measure of how well the bullets retains its origional velocity against air resistance)(to not slow down)

GL and if you need help converting everthing to meters for the hell of it ive got the numbers :S

When you zoom your scope does the impact point change on the target? is that when you use mil dot?

No, the cross hairs remain fixed. The zoom serves only to magnify the field of view.

Combinations and Permutations

You can enter combinations and permutations.

If the order of the selection matters (ie. 1st, 2nd, and 3rd place out of 40 contestants) use permutation. Enter:

40{shift}{nPr}3 and then [=] for your answer set (=59280 possible ways).

IF order doesn not matter (ie. a team of 3 from 40 possible members) then it is a combination. Do the same as above, but substitute {nCr} for {nPr}. (= 9880 possible ways).

For your question: a three-digit set, selecting from 0-9. There is no specified order, it is a combination. The total n=10 (there are 10 digits in the range 0-9) and you are selecting 3.

so.... 10[nCr]3 with give the number of possible combinations.
