View Full Version : Sure-Loc with Viper Scope Problem on 2012 Pantera

I put a Sure-Loc 400 with a Viper Scope on my Pantera and experiencing tuning problems. I moved the mounting bracket to the left on the adapter plate and had to move the horizontal bar to the farthest right of the slide and turned the micro knob to almost max out to the right. I cannot get the scope pin, arrow, bow string, and riser to align perfectly. When shot the arrow moves to the right of the target and I do not have any more adjustments available. Verticle appears to be fine but when using the sight pin, the arrow moves to the right. Any ideas as to what I should do next? Thanks.

im having the same issue out of my alien, except my sight is bottomed out all the way. everything lines up, but the arrow is dropping crazy....if its shooting that far right, i would do a paper tune and see if its tearing hard right on the paper as well, at least that will let you know if its more of a tuning issue or a sight issue

I own 4 Sure Locs, 3 400s and 1 550, half dozen different scopes and I can sight them in on any bow. So you have something wrong and unless there is something you haven't noted I'd suspect bow tune and probably center shot, not sight problems.

So we need some information. what's shooting through paper look like?

Note; For the vast majority of all bows the sight pin will be a bit left of the string with the arrow aligned to the string. Opposite if left handed.

I will do the paper test as well as adjust the Ripcord SOS rest setting to see if I can get the center shot more finely tuned. I thought I had everything aligned but remembered something in the Ripcord information that places the arrow shaft center about 1 inch from the riser side. Will post my results later. Many thanks to all.

@typical 8....yes ive considered that option but dropping it below my jaw still doesnt raise it enough. 14-16" low at 10 yards. worse and worse the further you get....martin has it they are looking at it for me

I'd be interested in Martin's response. Please post their response when they get back to you. Thanks.

I received some input from Sure-Loc customer service and they referred me to page 10 of the owners manual that they emailed to me. It is more comprehensive than the one that I got from the previous owner with what appears to be more information on all their sights and scopes. Turns out that I had to invert the Sure-loc Offset bracket and move the sight bar to the middle holes. I also lowered the vertical mount higher to bring the vertical micro adjustment knob into mid-point range.

I guess I needed to learn the multiple variations of the Challenger 400. As of now, everything is aligned as it needed with micro adjustment options functional. Thanks for the other recommendations for tuning the center shot. It is much appreciated.

So, not properly assembled. Okay.

You should have ordered the Sure Loc manual that comes with the Sure Loc. Assembly, parts, accessories. Some go for the Leathal Weapon, a five pin sight that adapts to the sight frame.

Something to use for the Sure Loc, Xsight by Richard C. Brown. You can find it on the internet. It's a free program. It's work with the Grid Scale of the Sure Loc. I use it for all my Sure Locs. Being Super Senior in ASA my max is 40 yards.
Sight in 3 yardages, 15, 25 and 35 yards is good. Plug in yards, Grid scale mark and number of clicks for each. Program will then print a chart showing grid mark and number of clicks for every yard from 15 yards to 54 yards. Printed chart is about credit card size. I plastic coat mine. I call it my cheat sheet and carry it in my pouch of my quiver. Nice about it, I don't have to cover my sight scale as per ASA rules.

example of; 21 yards is 27.05 using the scale and vertical knob for clicks.

Or if you wish, the program will print a colored scale to stick on the Sure Loc. You have to have the stick on type paper.

Hint for XSight; The more accurate you are in finding the correct setting the more accurate the program. You want a short yard, like 15, and the intermediate and a longer yard, like 35 or even 40 yards.

Accuracy of the program. Early last year or year before I entered only one long range Novety shoot. Yardage was given, 52 yards. The target was a 2" diameter orange clay disc. I set my Sure Loc for the yards, drilled the disc and won.

Many thanks for the tip and the website information. It always amazes me how much information and knowledge you have in addressing my various questions over the past few months. You are a great asset to the forum and newbies like myself.
