If the instrument is handled with due care, it will give you long and trouble free service. Like any other delicate instrument, your binocular also requires protection.  The same principle applies to other instruments like the spotting scopes or rifle scopes.

Storing binoculars with the eyecups made of rubber on will avoid stress and prevent unwarranted wear and tear. It will also protect the lenses from dust and other unusable particles that can damage them. You should also try to avoid banging or dropping of the instrument as far as practicable because such actions may damage your instrument at times beyond repair.

Do not view the sun directly through the view finder. Always adjust your rangefinder in such a manner that your focus is not directly in line with the sun. Store your binoculars in a dry and cool environment and never stuck them in your automobile where the temperatures are liable to fluctuate frequently. This may damage the optical lenses of the instrument. Handling with care is always essential for any instrument and so it is for your binoculars.

Binoculars in the dimension of 7X50 or 10X50 could be excellent instruments for astronomical purposes. However, if the binocular is large with a higher rangefinder capability, they may have to be mounted on a tripod usually taken for mounting a camera. Smaller binoculars can also be used but the images may not be bright to your liking.

You can also think of the spotting scopes for the purpose but it is normally the telescope which is used for astronomical study purposes. To use a binocular for the same purposes you may be on the look out for a well built light weight instrument. If it contains quick focus system that will be a bonus gift for you.

Zoom lenses and fixed focus attributes may be good for instruments like rifle scopes but are not suitable for the astronomical studies. Sometimes you will face a problem with undersized binoculars because the light you will see may not be circular and there could be flat edges. This will distort the view and the images could be blurred beyond recognition. Once you take care of these small points, the binocular can serve you for astronomical studies.

The law enforcing agencies often use mace pepper foam that is used to identify the attacker quickly and faultlessly.

But if some one is able to get past that security belt, you do not have any means of self defense available. The same is also the case of the electronic pocket whistle. You may or may not get the chance to use it at the real time. By the time you whisk the whistle out of your pocket and try to blow it, the attacker may be all over you depriving you of the chance to use it.

Michigan and Wisconsin have imposed restrictions on the use of pepper sprays in their states. In Michigan you can use pepper spray but the pepper concentration must be limited to 2% only. No combination spray can be used here. In Wisconsin you can use pepper only with a 10% concentration.

Ordinarily the stun guns use high voltage and low amperage that would work extremely well to temporarily disable the attacker. The affect remains for a period that would be sufficient for you to seek help or run away. However, you must check for legality since stun guns like the stun master 625000 Volts may not be legal in all states.
