10 - Dummies Guide To Parallax & Cant Errors and How To Fix Them

Thanks for the info. I am female and new to air rifle and air gun shooting and really enjoying it. I find your approach to putting information over as really helpful. I don’t always understand it, particularly the maths - cosines and stuff - but you have a gift for making things easy to understand. 👏 I am working my way through your videos from the beginning. Thanks very much 👍

Jeff, I have to lift my hat to you🤠. Probably the best explanation of parallax error I have come across with demo that is definately worthy of a "Blue Peter" badge. Worthg noting in the calculation that the target range and focus range are "unit less" as they serve to form a ratio, could be yards, metres or even lamp posts as long as both use the same 😀

Thank you so much you solve my problems now i smile😊 may rich God bless you abundantly

A brilliant video, one of the clearest explanations out there.

Another really well presented and informative video. Keep up the good work. Looking forward to your next one.

32 mm scope , medium mounts , and plumb line at 10 yards 👌 and prevents parrallax , good video.

Hello. Simple but excelent explanations. Keep on rocking those videos. Muchas gracias amigo!

Good video, keep them coming. I have learnt something today as well, that is a very useful formula to work out max error, so thanx for that, cheers.

Very informative and interesting videos you are doing, keep up the good work

A lot of modern scopes have parallax adjusters, to eliminate the problem. They also help with rangefinding. Great video. Thank you. 😊

interesting video cheers , love the channel

Great vid... Thanks chap!

Excellent deep dive and explaination 👍👍👍👍👍👍👍👍👍👍😎😎😎😎

Grown up adults all laying in mud with guns......have i died and gone to heaven lol

I am not a HFT shooter but a sub 12 air rifle hunter and found your videos very informative and useful thank you. I also like your presentation style. Being old I like the way you speak what I would call normal for example you say "Hello, and welcome to the channel" not HI GUYS. Sorry but cannot stand the use and overuse of the words "GUYS" which seems so common these days! I think your channel will do well if you stay keen to make the big effort it takes to produce these videos.

Great video to a new shooter.. my girlfriend looks parallax to me every weekend I cant get her in focus.. she's out of focus at 3 am in the morning.. there's four of her..😂😂 now I can show her this video.. now I have to explain to her CANT.. or she WON'T... its getting complicated now but I'm going to her this video and maybe I'll get lucky.. 😂😂😂 joking of course.. very good info again... I did the plum line in my toilet.. and a torch flashing through the scope.. spirit levels.. bang on.. I would love to do a HFT... but I'm a bit scared.. thanks again.. your a good Teacher.. 👍🤘👌

Thanks for the video. Great info and well explained. I just purchased an Air Arms S510 xs FAC which will be used for ratting. I am a well experienced 22LR shooter and an old springer hw97 guy but new to pcp’s. Im hoping that you could advise me of what you think is the best zero and magnification for my rifle? I will be shooting at distances from 20 - 60 yards. Any advice would be appreciated. Many thanks Stay well Ash from Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿

I'm a high powered rifle shooter and your formula was very helpful in determining at what point I may need to address parallax. So thank you for that! BUT, my problem with scope mounting is how to be sure my rifle is perfectly straight up & down when going to the plumb bob? Is it safe to assume (I hate making assumptions) that the machining on the gun, rings & bases are perfect?

Hi there...... I like watching your videos..... but on your point of Cant Error, ........ from my point of view shooting 10mtr targets with open sights (Diopter) I always shot stood up perfectly straight and then I had a bit of coaching from a National and International 10mtr coach and the first thing he said to me was Cant the rifle ....... the outcome was a more consistent shot and a more relaxed position.....AND I never altered my Diopter at all, and I have my rifle at a serious angle now.......

Getting to know you... Maths and models... I like it. Difference in magnification between your two samples might be down to which sights were cheapest/best known/best marketed/ brightest image at the time - or copying the scope chosen by the best marksman of the day, or nowadays whose videos get most views on YouTube... x9 or x10. Why 23 yards would have been a popular zeroing range for parallax for HFT puzzles me. The mid-point from 8 to 45 is 26•5 yards, so 23 yards makes no sense to me. Could it be down to the change in chosen magnification? If the preference was for x9, did that affect focus too much at short ranges, nudging HFT competitors to choose a shorter range for zeroing? You get nerdy about the maths, I get nerdy about Human Factors: If you use a x10 scope for acceptable focus at short range, you're likely to zero for parallax towards 26.5 yards - but for the HF that test firing is easier on the 25 yard range at the competition venue. HFs often trump science, but I still like your maths and models.
