Peep/no peep
A peep sight provides a small aperture on your bowstring to look through and align your sight pin(s) for the correct distance. Since this establishes your anchor point, it's an important part of your shooting package. Peeps come in various sizes and are sometimes aligned by a rubber cord attached to the bow frame.

Peep sights with small apertures are difficult to use during low light situations. You can improve a peep's usability by using a larger aperture, but that isn't a cure-all. Larger peeps increase the margin of error. A new concept is to use an even larger peep with a sight that has a circular frame and align the circle with the peep.

Eliminating the peep altogether might be a better concept for you, especially if you wear glasses. If peeps are a pain for you, another concept that's worth considering is electronic enhancement Sight's like the Accu-Tech, M-Point, Micro-Fire or the ever popular Accu-Shot.

Laser, Holographic and Red Dot Sights
Electronic sights that project a laser beam to the target are quite effective in low light situations, but during bright daylight and you could be hamstrung. This problem is also magnified as distance increases and the beam's brightness diminishes. A more practical approach is red dot sights that project the beam of light back toward the shooter. With the shielded sight lens, and variable intensities of the beam, red dots are far more versatile and effective.

Holographic sights are also immune to the difficulties of bright light. This new concept delivers remarkable and repeatable accuracy, instant alignment confirmation and superior low-light visibility - all in one sight. It's really an ingenious device that shows you when you're misaligned or peeking. A hologram of a reticle pattern is recorded on a heads-up display window and when the two rings are aligned you're ready to release.

Since electronic sights have no pins to bend or break off, are highly durable, eliminate peep problems and are extremely easy to use - they solve a lot of problems. When I consider the number of sights that have collected in my box of bow goodies, the cost is about the same, or even less.

Finding the perfect bow sight for the area you hunt and techniques you prefer may take some experimentation but that's part of the fun of shooting a bow. It's a primeval sport with high-tech doodads that are designed to improve your ability to perform in the field, and it's always interesting to try new concepts while searching for archery's Utopia. Just keep in mind that there is no substitute, either mechanical or electrical, for practice. This is especially important when you have a new sight. Practice is by far the best investment you can make toward attaining that trophy buck you seek.
