I have a cobra digital camera, what kind or another memory card I can buy it?

Cobra is a 6 megapixel could I just get a generic at Walmart?

take it back and get a name brand camera. (Canon, Sony, Fuji, Panasonic, Casio, Nikon, Pentax, Olympus, and Kodak) There are makes a difference. If money is really a problem - get a refurbished Fuji F20 on line (amazon) for ~ 89 $.

When it comes to walkie-talkies, a lot of people get confused by claims of manufacturers about the service range. It would probably help if someone the green light to the air on this to help, trying to sort out the ridiculously high expectations of the reach of many walkie Talkies. The following table it will be easier for most people to:

Claim Area Power Current Minimum Range Urban Range

8-12 Miles 1 W 1 / 2 to 1 miles 200 yards

18-20 Miles 2 500 watts 1 miles Yards

27-30 4 Watt, 2 miles 1000 miles Yards

Note that very challeging radio environments quickly cut your selection to the absolute minimum is sufficient here to to see or something between it and the city limits. Only portions of the amount they will take you to the Maxima, which the manufacturers claim. In any case, I'm the producer I said, test their radios unrealisitic held under conditions of facilities in the flatlands of Florida with unobstructed increased test platforms.

Discussion on 2-Way Radio Power:

Firstly, it is important to remember that the maximum legal powers to one GMRS walkie talkie is 4 watts. That is a lot of power when you consider that most digital mobile phones in these days of over 300 milliwatts or less work Most of the time. However, mobile phone use near an invisible network of "cell" sites all around us, on corners of tall buildings, hills and mountain peaks, so that they can reach and are rarely more than a few hundred meters. To have a walkie talkie, things the hard way, without the help of a cell site, you need a lot more force. In addition, four watts, unloaded the battery too quickly and requires little more expensive, larger and heavier to handle internal compentents the additional energy.

That said, spent all that time in the field with these things, know that reliable communication is the key. Some settings, such as for example, using radios car to car on urban streets or in heavily forested areas, the supply of cut even the most powerful radio stations of a few hundred miles on Meters. "Line-of-site" is the rule for radio stations like, so if you have height, your offer will be greatly expanded. With obstacles signals may be absorbed or reflected.

The rule of thumb is, even for someone just having fun with these radios, the more power the better. That is why I always recommend the additional Expenditure for $ 20 or so and get something that legally permissible uses. These additional watts helps when punching the signal through metal car seat Winows by wood frame houses and concrete structures. In the desert trees and rocks are similar obstacles for the radio signals, but as a safety device outside the radios really need to perform reliably in order to ensure the maximum performance for more peace in the pursuit of children and hiking partner. You can always choose the power to the battery for the preservation of the juice when you need it.

So if you are really the 5.5-inch size of the above Cobra LI5600 need radio, you can go for the increased power of the 7-inch LI7020, below.

Radios are inexpensive fun for the whole family. When in range, however, comes, keep your expectations realistic. Read your manual, you keep your settings as simple as possible and make it into both real and the urban jungle!
