The SPECTRA 4-16x50i Riflescope from GPO USA with the G4i reticle is an all-around riflescope with 4x magnification, perfect for those closer deer shots, and maximum 16x magnification for longer range shooting. The 50mm objective assists in better brightness performance on those dark or dreary days. This scope comes standard with DoubleHD objective lens technology, iCONTROL illumination, PASSIONtrac turrets that will assist your shooting. The 0.1 MRAD turrets adjust impact point at 1" per click at 100 yards, with a total adjustment range of 76".

GPObright is a proprietary coating process that maximizes light transmission through each surface of an optical element. As light hits an optical surface, normal uncoated high-performance glass can reflect up to 5% of that light, redirecting this light so it does not transmit through the optical system. However, when these high-performance lenses are vacuum-coated with GPObright lens coatings, up to 99.7% of the available light passes through each optical surface. Furthermore, when every surface of the entire optical system is properly coated, total light transmission can reach up to more than 92%, making the optical image of a GPO binocular or riflescope bright, even in the lowest light conditions.

A Double HD lens is the final product, created when multiple extra-low dispersion lenses are chemically laminated to make a single, multilayer high-performance optical lens. Laminating multiple lenses minimizes light reflection on the surface of multiple lenses, creates enhanced resolution and color contrast images, and minimizes chromatic aberrations. This benefit is clearly visible with all GPO products supporting this feature. This high-performance process is routinely found in the photographic market and with the highest quality photographic lens manufacturers, but has now transitioned into premium sporting optics.

With internal components built from aluminum and brass gearing systems, PASSIONtrac ensures reliable and consistent adjustments when operating the turret. In addition to the high-performance internal components, PASSIONtrac also has a simple turret disengagement feature. This allows the user to reset the turret so the zero-mark located on the turret can align with the zero-indicator mark located on the scope tube body. After sighting in the rifle, the user needs to only lift the turret to disengage the turret threads, rotate the turret to where the zero-mark on the turret is aligned with the zero-indicator mark on the scope body, and gently press the turret down until it clicks into place. This ensures that if the shooter ever needs to make a turret adjustment in the field, they always know where their zero origination began. An additional benefit of PASSIONtrac is its intended use for shooters who regularly dial their turrets. PASSIONtrac turrets are engraved in easy-to-read MIL or MOA markings and follow MIL or MOA point of impact adjustments. Shooters can operate this product like a tactical MIL or a hunting long-range MOA turret: dialing, reading, and shooting. Hunters have the advantage of protecting a dial turret with a machined aluminum turret cap.

Q: 1. Is this still made in USA like the earlier Spectra IV was?

A: The Spectra Cine PRO V Exposure Meter with TFT Display is manufactured in the US.

Q: 2. B&H # OPSSOSB MFR # 901012 What is the overall length of this strap, minimum to maximum?

A: The strap should accommodate all size hands as the strap is adjustable at both ends. It's roughly 13 inches end to end, but I didn't want to undo it from my camera so this is approximate. I have thin fingers/hand and after adjusting it to a snug fit, there is 2 inches of strap left over at either end. BTW I love this thing. I leave it on all the time. I have an around the neck strap that uses snap connectors (which also stay on the camera), but I leave the strap in the bag most of the time. If you need to be mobile (such as street photography, sports or photojournalism style) this is great. The camera just becomes an extension of your arm.

Q: 3. what is the diameter of this dolly?

A: The diameter on this dolly is 36 inches.

Q: 4. Can the wheels be removed and replaced with track wheels?

A: Yes, the regular wheels can be removed and replaced with track wheels. The ProAm USA SolidTrax Universal Track Dolly Wheel Assembly B&H # PRDLSTW, will work great with the ProAm USA Professional Tripod Dolly. However, if you wish to go straight to track, you could consider the ProAm USA SolidTrax Universal Track Dolly B&H # PRDLST. It comes with the track wheels installed.

Q: 5. Can this battery be used as a replacement with Parrot Anafi which uses 2700mAh, 7.6V battery ?

Q: 7. Will this work with a c-stand?

A: Not that we are aware of. If you are looking to have a mobile C-Stand we suggest purchasing the Kupo Runway Stand Base, B&H # KUKS301012, along with the Avenger A2014 20" Double Riser 4.5' Column for C-Stand (Chrome-plated), B&H # AVA2014. This combination will give you a mobile and secure C-Stand. https://bhpho.to/2HKL6us https://bhpho.to/2QB9nq0
