Swift has been in the business of developing and importing quality optical products since 1926, when the first roof prism binoculars were imported from Germany. Since then, Swift has added spotting scopes, telescopes, specialty optics, riflescopes and weather instruments to there family of optical products.
Swift introduced the model 804 8.5 x 44 Audubon binocular in the early 1960's and continued its production until 1999.With the turn of the millennium this venerable 40-year-old product was supplanted by the new waterproof Model 820 Audubon, which clearly carries on the porro-prism tradition of the original, and has received justifiable praise. Nonetheless, many users of the older versions look back fondly on the stalwart No. 804.
This is an older model 804. Produced in 1982. The other one, with the F.O.V. in meters, is produced in 1983.
Like the other Audubon models, They are very clear and bright bino's, with a very wide angle of view. They have Bak4 prisms and glasses and are heavier and larger than their successor.
