Bushnell Forge vs Engage 20-60x80: Which Spotting Scope Fits?

The real decision: Porro or dielectric?

Both the Bushnell Forge 20-60x80 and the Bushnell Engage 20-60x80 share an 80 mm objective and a 20-60x zoom range, so at first glance they look like the same tool. The differences that matter are in the optical path, the eyepiece design, and the mounting features. The Forge uses a Porro prism with BAK-4 glass and a 45° angled body; the Engage uses a dielectric coating on its prisms and a straight-through design. Neither is automatically better for every observer—your choice depends on whether you prioritize viewing comfort and contrast or compactness and red-dot compatibility.

Optical design and coatings

• Prism type: Forge: Porro prism with BAK-4 glass. Engage: not specified in the supplied catalog; only the dielectric coating is mentioned.
• Coatings: Forge: fully multi-coated optics with EXO Barrier on the exterior. Engage: dielectric coating plus EXO BARRIER and multi-layer coatings on all surfaces.
• Eyepiece: Forge: twist-up eyecups and 18 mm eye relief. Engage: eyecup type and eye relief are not confirmed by the supplied information.
• Focus system: Forge: dual focus system for fine adjustment. Engage: focus type not specified in the supplied catalog.

Forge: comfort and contrast for long sessions

• Lunette Terrestre Bushnell Forge 20-60x80: 45° angled body with a rotating tripod ring. The angled design lets you observe comfortably for long periods without craning your neck, especially when subjects are above the horizon. The rotating ring helps you position the eyepiece when the scope is on a tripod.

  

• Lunette Terrestre Bushnell Forge 20-60x80: Porro prism with BAK-4 glass and multi-layer anti-reflective coatings. This combination is intended to deliver high contrast and light transmission, which can be an advantage in low-light conditions such as dawn or dusk.
• Lunette Terrestre Bushnell Forge 20-60x80: 18 mm eye relief and twist-up eyecups. Generous eye relief makes extended viewing more comfortable and can be helpful if you wear glasses, though the catalog does not specify eyeglass compatibility.

Engage: compact and red-dot ready

• Longue-vue Bushnell Engage 20-60x80: Dielectric coating on the prisms. Dielectric coatings are used to improve light transmission and color fidelity, which can help produce clear, bright images.

  

• Longue-vue Bushnell Engage 20-60x80: Picatinny rail for mounting a red-dot sight. If you want to quickly acquire a subject before zooming in, a red-dot sight on the rail can speed up target location—a real benefit for hunting or fast-moving wildlife.
• Longue-vue Bushnell Engage 20-60x80: Aluminum chassis with rubber armoring and a compact design that fits in backpacks from 30L. This makes the Engage easier to carry on long hikes or backpack hunts where space and weight are at a premium.

Weight and portability: what the catalog does and doesn’t say

The Engage is described as compact and easy to transport, fitting into small backpacks (from 30L). The Forge is described as robust and durable, but neither product record lists an exact weight. If weight is a deciding factor, you will need to confirm the actual figure from the manufacturer or a retailer—the supplied information does not provide it. In practice, the Engage’s smaller footprint and straight body often make it the more packable option, while the Forge’s angled design and Porro prism typically add bulk but may offer a more comfortable viewing position.

Price and value

At the catalog prices shown, the Forge is positioned as the premium option and the Engage as the more accessible one. The Forge’s higher price reflects its Porro prism, dual focus, and angled body—features that can matter for dedicated long-range observation. The Engage offers dielectric coatings and a Picatinny rail at a lower price, making it a strong choice for hunters who want to add a red-dot sight or for anyone who prioritizes portability. Neither scope includes a tripod in the supplied information, so factor that into your budget.

Which scope suits your use?

• You watch from a fixed position for hours: Choose the Forge: the 45° angled eyepiece and 18 mm eye relief reduce neck strain, and the dual focus lets you fine-tune sharpness.
• You hunt and need to locate game quickly: Choose the Engage: the Picatinny rail accepts a red-dot sight for fast target acquisition, and the compact body fits easily in a 30L pack.
• You often observe in low light: Both scopes offer 80 mm objectives and anti-reflective coatings. The Forge’s Porro/BAK-4 combination is described as delivering high contrast; the Engage’s dielectric coating is described as improving light transmission. The catalog does not provide a direct low-light performance comparison, so consider trying both if possible.
• You wear glasses: The Forge lists 18 mm eye relief and twist-up eyecups; the Engage does not specify eye relief or eyecup type. If comfort with glasses is critical, the Forge’s published eye relief gives you a concrete number to check against your needs.

What the catalog does not confirm

Neither product record lists a field of view at 1000 yards, close focus distance, exact weight, or waterproof/fogproof rating beyond the EXO Barrier coating. The Engage’s prism glass type (e.g., BAK-4) is not stated. These omissions mean you should verify any specification that is critical to your decision—such as weight for backpacking or close focus for backyard use—with the manufacturer or a detailed retailer listing. The absence of a specification here is not evidence that the feature is missing; it simply is not included in the supplied information.
