The Swarovski Optik 5-25x52 dS Gen II SR Digital Riflescope takes all the guesswork out of shooting to greatly improve your accuracy—when you're shooting anywhere between medium and extreme long range.

Equipped with the Swarovski Rail no-ring mounting system, the scope features a wide zoom range and an oversized objective that allows you to use it for large and small game in all light conditions and keeps views bright and clear, even at long ranges. It comes with the full complement of optical coatings to maximize light transmission and keep the lenses clear and clean.

Beyond the optical performance you'd expect from a Swarovski riflescope, the dS is packed with a suite of electronics and tools to get you on target, starting with an integrated laser rangefinder and inclinometer. These measure the distance and relative angle from you to your target and, using low-power consumption Bluetooth connectivity, transmit that data to your smartphone running a companion app for iOS or Android devices. The app takes the distance and angle transmitted from the scope and adds information you've entered—such as your rifle and ammunition load, altitude, air pressure, wind speed, and temperature—and calculates an adjusted aiming point, which it transmits back to the scope. With this new aiming point determined, the illuminated aiming point on the reticle is moved to the appropriate position. Now, all you need to do is put the dot on your target and squeeze. At no point do you need to manually adjust your turrets, so your rifle remains properly zeroed at all times.

Protecting the optics and electronics is a large 40mm aluminum maintube and housing that is treated with a scratch-resistant anodized finish. The scope is nitrogen filled and O-ring sealed to be waterproof and submersible to 13 feet and resistant to internal fogging, even in extreme conditions and temperatures. Front objective filter threads allow you to install polarizing or specialty filters to further improve performance, while the included clear lens caps give you another level of protection with the ability to use the scope with them on. The illuminated reticle, rangefinder, inclinometer, and Bluetooth are powered by a single included CR123 battery.

Q: 2. My imac and macbook pro are USB2 which one is faster? Apple SD Internal Slot macbook mid 2011 or ProGrade Digital?

A: The now-aging USB 2.0 standard can theoretically transfer data at 480mbps (60MBps). The newer USB 3.0 can handle up to 5gbps (640MBps)—over ten times as fast as the 2.0 maximum. How fast can a Mac read or write to a SD card in its SD card slot? Mac notebooks (laptops) use the USB bus to communicate with the SD card slot. They have a maximum speed of up to 480Mbit/s. Mac desktops use the PCIe bus to communicate with the SD card slot. Desktops can transfer data at a faster rate. Check the packaging that came with your SD media to determine the maximum transfer rate that your specific card uses. To determine the maximum transfer speed of your Mac, you can use System Information. Choose Apple () menu About This Mac and then click System Report. If you use a Mac notebook: 1. Select Hardware, then select USB. 2. Select Internal Memory Card Reader and look for the Speed entry. If you use a Mac desktop computer: 1. Select Hardware, then select Card Reader.  2. Look for the Link Speed entry. Computers that use the PCIe bus express their speed as GT/s. Excerpt from: https://support.apple.com/en-us/HT204384
