Congratulations on your choice of a BUSHNELL® HOLOsight®, a revolutionary sighting
system based on advanced holographic technology. The BUSHNELL HOLOsight enhances
target acquisition, improves accuracy, and provides more control over your shooting
environment.
The BUSHNELL HOLOsight fills the needs of all shooters from the novice to the most
advanced professional. Our objective is to give each and every customer the quality,
commitment, and service expected from the sighting industry leader. Whatever your shooting
discipline, we wish you the best shooting, and again, we thank you for choosing the
BUSHNELL HOLOsight.
Please read the instructions carefully before mounting and using the sight and always practice
proper firearm safety.
Included: Sight assembly, 2 AA or N alkaline batteries
You will need a 7/64" Allen wrench.
BASIC OPERATION
The BUSHNELL HOLOsight uses laser light to illuminate a holographic reticle pattern embedded
in the heads-up display window and forms a virtual image of a reticle pattern. The shooter looks
through the heads-up display window and sees a bright red image of a reticle pattern projected onto
the target plane. There is absolutely no light projected onto the target plane, and the sight is legal to
use in most shooting and hunting situations. The BUSHNELL HOLOsight has no magnification.
BATTERIES
Depending on the model, your Holosight is powered by either (2) N alkaline 1.5 V batteries or (2)
AA batteries. An initial set of batteries comes with your sight. The BUSHNELL HOLOsight is
designed to maintain constant brightness at a particular setting. The reticle brightness will not fade
gradually as the batteries run down but rather shut down abruptly. The first indication of the
batteries draining is the reticle blinking when the unit is turned on. Another indication of low
batteries is the reticle pattern blinking off and on during recoil. With high recoil guns, this can occur
before the battery check indicates low battery condition. If the reticle pattern blinks off and on
during recoil or turns off suddenly, replace the batteries. Alkaline batteries from different
manufacturers are not all constructed the same way. Tests show some brands are more susceptible to
degradation by the shock of recoil.
Model 51-0021 – is powered by two N type 1.5 volt Alkaline batteries. We recommend the use of
EVEREADY® ENERGIZER® batteries with the Bushnell HOLOsight in cold weather. Please
note that there is a 12 Volt battery that is approximately the same size as the Type N 1.5 volt battery.
DO NOT USE THE 12 VOLT BATTERY. It will severely damage your sight.
Model 52-0021 – is powered by two AA type 1.5 volt Alkaline batteries. The AA HOLOsight can
utilize various types of batteries. Bushnell recommends Energizer batteries for regular use. NiMH
rechargeable batteries are the most cost effective in the long run, but do need to be charged regularly
as they do not hold a charge in storage well. For cold temperatures, Lithium AA batteries offer the
longest battery life. However, please note that the battery test function which is designed to work
with Alkaline batteries does not function accurately with Lithium batteries.
It is a good idea to change batteries before an extended hunting trip or match. For a comparison of
battery life at various temperatures, please see the graphs :
REPLACING BATTERIES
Remove the battery compartment by lifting up on the locking cam lever and carefully sliding the battery
compartment away and up from the sight housing (Figure 2). After the battery compartment is removed,
slide the batteries out and replace them with a fresh set. The labels on the bottom of battery
compartment show the correct battery orientation. To re-install the battery compartment, point the
sight towards the ground and slide battery compartment onto base. Make sure there is enough clearance
between the contact and the batteries to avoid bending the contacts. Hold the battery compartment
down firmly against the base and close the locking cam. Before you push down on the cam lever, make
sure the battery compartment sits all the way down and parallel to the base. Verify correct battery
installation immediately by turning on the sight and checking if the holographic reticle appears.
