In your choice of Which is better for wildlife safari, you will have to consider what you are actually looking out for first. Do you want some thing light and portable at the expense of some extra comfort and convenience? Or you would rather be as relaxed as possible and get all the glimpse in style but bear the burden that comes with this. Monocular are Sometimes perceived as inferior to binoculars for wildlife viewing because of the flatter image derived from a single objective lens. But monocular have the advantage of being easier to carry and lighter in weight than binoculars. A monocular can fit in your pocket or be carried on a strap around your neck or looped on your belt. Although Observing with both eyes open is certainly more comfortable and relaxing than just with one.

Actually, the green ones are considered better and have a much higher price tag as well. Red laser sights can be hard to see in daylight. Green ones appear brighter in those conditions.
The red ones have been around for a long time because the engineers figured out how to mass produce them before they figured out the green lasers.

The illuminated reticles of optics are generally red and green to allow for better contrast against various dark backgrounds while also not sending a piercing light into the eyes of the shooter. Red and green are also typically not as noticeable from the barrel side of the gun as a color such as white would be.

Not really. The second you fold it you lose your zero, because it will never rest in EXACTLY the same place, so although at shorter ranges it might work, at longer ranges it will be essentially useless.

Bushnell Scout DX Rangefinderis my favorite one. It's a fantastic range finder.
It's offers some amazing feature and specification like...
  • 6x magnification
  • Range between 5-1000 yards
  • 3-volt CR2 Battery
  • Rangefinder Accuracy 5 yds
The Bushnell Scout DX Rangefinder will help you to pick from 3 different user modes by pressing the Mode button at the left side of the unit. First is the usual mode which can be used for most purposes up to 1000 meters and works well towards the pretty reflective surface.
When turned on, the Scout 1000 Laser Rangefinder liquid crystal display (LCD) will directly display icons like the bow and rifle mode. The bow mode will provide you with true horizontal distances from 5-99yd away, depending on the angle. The rifle mode, however, will permit you to get the angle and drop/holdover of your shot to the target from 100-800yd.

Earth. That's it. The moon isn't a planet.

No way of really knowing the number of people who have walked on Earth. It's a tad over 7 billion right now but how do you count all the ones who have lived and died?

The biggest advantage of Holographic Sight over red dot is that prevents parallax distortion.
That is if your eyes are not properly aligned with sights in a red dot sight you will not hit what you are aiming with your sight, as you will not be looking parallel to the barrel of the weapon. This problem increases with the range of the target.
Holographic Sights, however, uses laser to produce a holographic reticle, which is not very prone to parallax errors.
However, there must be something which keeps Red dot in demand.
