I'm trying to figure out the bottom part.
What does the bottom part represent?
About half way down the page is a good description of the choke. Its calibrated to 18", the width of a mans shoulders, and is a fast way to range with any 18" target. Way better to read the original than try for my repeated info. This is written a little more clearly than the original...
Well, mine at max magnification, an 18" target doesn't cover half of the top choke line at 100 yards.
18" target covers the top choke line at around 10 yards at max zoom
I haven't checked the central portion
"/ The range finding choke is calibrated for the LOWEST POWER
ZOOM SETTING for the particular optic model."; from the manual.
The choke only works at the base magnification in 2nd focal plane models. As magnification is increased the etched surface gets magnified also. Throws the etchings out of calibration. First focal plane scopes don't have this problem, but they carry higher price tags. Run the magnification down to base and the choke should work properly for you.
At the lowest magnification the target covers about 1/5 of the top line at 100 yards
At the lowest power zoom: 6x, the top line of the choke covers 11" at 7 yards.
If the lower power is used with the choke, what magnification do I use with the cross part of the reticle.
And no, on a second focal plane scope the reticle stays the same size as the image zooms.
I don't want to tell anyone their business, but according to the manual, if a target takes up one segment of the cross hairs ie 6 mils, that target is at 187 yards. Something like that. Now that's all the way zoomed out for the target to be small enough to only take up 6 mils. Now, I shift the target down to the choke and a target that was ranged at 187 yards without zooming in any, maintaining minimum zoom level, according to the choke, the target is now 1000 yards away.
I think the manual has a typo. I think it should read that the choke is used at maximum magnification.
I made a video explaining it
I've been looking at the scope more and the p4 portion looks to be accurate but I think the choke is calibrated for deer.
Don't you just play with the screws on the top and sides of the scope until you hit the bullseye?
I did with this scope. I don't have a bore sighting tool so I had to fiddle a bit.
If you look at the instructions put out by trinity force or Steve or whoever, it says the p4 is used at the lowest zoom. But then on page two it says use the choke at the lowest zoom. The top line of the choke represents 18" @ 100 yrds at maximum zoom
Seriously, no further comments on this subject by ANYONE? wow?!?!
your lucky to range within a +- 1000yards with a trinity force optic. these are barely airsoft quality from what i am seeing.
my opinion zero it ignore the lines as they are likely far far far from any sort of accuracy.
an accurate reticle with any resonable accuracy is a couple hundred just for the reticle and lenses much less the rest of the optic at manufacturer cost
