Aid volunteers often work in a high risk environment, be it from civilians fighting for aid or political conflict and fighting. Working in a foreign environment can often be quite a strange experience and it's important to make the team feel at ease and as comfortable as possible so that they can concentrate on the task at hand.
In addition, we have begun to take these motorola DP4400 radios hunting with us since the land we hunt on is huge and we like to know when people leave. Which can be a great time saver when somebody leaves so you're not walking through the woods trying to find someone who is not there.
Now that I have established that I'm not anti-smart phone, I would like to point out why you may not want or need one. A smart phone usually uses more power than a regular cell phone, this means constantly charging it. A motorola radio RAZR can stay on for 3 days; a smart phone used moderately will stay on for 1 day at best. If you plan to go on a long trip without an outlet where you can charge your phone, be sure to leave your power chugging phone at home.
Also, you need a good high-speed modem for the Telo to work properly. I tried using a motorola dp4400 Surfboard in hopes of replacing the one I rent from my cable company, but it just did not seem compatible. It works fine with the cable company's modem, though.
This simple system is easy to use. One of the best and most exciting benefits from having your own On-Site Two Way Radio System is that you will not have any monthly air time bills to worry about. Surcharges, overages, and hidden taxes are a thing of the past to customers who switch to Two Way Radio On-Site Systems. Now instead of having a cell or Nextel bill every month, they have none.
From a safety standpoint PURPLE is the color that ensures a successful motorola two way radio cruising life but I don't think the sailing community will ever leave pink and blue behind!
