The ed­i­tor de­scribes the var­i­ous types of tur­ret ad­juster and ex­plains the dif­fer­ence

The vast ma­jor­ity of con­ven­tional scopes have a cen­tral ‘sad­dle’ on which we find ad­juster drums for windage, left to right, and el­e­va­tion, which is up and down. Th­ese are used to en­sure that our pel­lets are land­ing ex­actly on the ret­i­cle (cross hairs) at a cho­sen dis­tance. Most move a de­fined amount with a tac­tile and au­di­ble click, that helps us to make pre­cise changes.

In the past, the ad­juster drums were low to the scope’s body and cov­ered with a screw- on cap that aided weatherproofing. The cap also en­sured that the ad­juster could never be moved ac­ci­den­tally, thereby af­fect­ing your zero. For most peo­ple, this de­sign is just what we need, and as a hunter they’re the only type I use. Once I have my ri­fle per­fectly ze­roed, I like to lock ev­ery­thing down se­curely so I have to­tal con­fi­dence that it will be cor­rectly sighted ev­ery time I take it from the gun safe.


In re­cent years there’s been in­creas­ing in­ter­est in the se­cond type which goes by sev­eral names, in­clud­ing sniper and ex­posed tur­rets. Th­ese are typ­i­cally tall and large, dis­play­ing all the ad­just­ment in­for­ma­tion on their out­side. This al­lows in­stant ad­just­ments to be made, even with gloved hands and it’s very use­ful if you like to ‘dial’ in your cor­rec­tions for dis­tance and the wind. This is the tech­nique used by mil­i­tary snipers who might well en­gage the en­emy at 1000 yards or more. How much of a ben­e­fit that tech­nique is to the air­gun hunter pur­su­ing his quarry in­side 35 yards is open to de­bate, but in field tar­get ( FT) com­pe­ti­tions they’re used all the time. The shooter makes very pre­cise ad­just­ments to en­sure that the pel­let’s tra­jec­tory is com­pen­sated for at ranges from 8 to 55 yards which is a tough test for a sub-12 ft.lbs. air­gun pel­let.

Early ex­posed tur­rets were free to turn at all times and peo­ple had bad ex­pe­ri­ences with them get­ting ro­tated ac­ci­den­tally and their zero be­ing lost. I’ve been wit­ness to that prob­lem and I can tell you the hunter con­cerned was re­ally an­noyed. To­day most have lock­ing mech­a­nisms that avoid this prob­lem all to­gether, so be sure that any scope you buy has this im­por­tant fea­ture.

As ever, spend­ing a lit­tle time weigh­ing up the rel­a­tive mer­its of the types will help you to se­lect the right one for your type of shoot­ing.
