Refer to outdoor activity, a leader of professional outdoor crew told me that they have no idea what traditional so called “three-proofs” smartphone is, whereas, he did actually pointed out three main aspects to facilitate safety instead, strong mobile phone signal receiving competence, GPRS network or maps and digital compass.
Exactly as your imagination, for any outdoor smartphone, a strong communicative competence is not so much a method to keep in touch as a vital guarantee of survival when necessary. If someone get injured or trouble, smartphone like Discovery V5 can always be available asking for first aid even miles away from hospital. Just about a strong mobile phone signal and high-quality talk time, has squeezed the most valuable time for rescue, which is priority among priorities without a doubt.
Besides, despite of papery map has substituted by digital map ever since technology getting maturer and sophisticated, none of us will deny its importance whatsoever. When taking an adventure with where you don’t get well-familiar, it is not always easy to find the way out unless with the assistance of some high-tech application. Hence, it is time to take out Somin A8 which equipped itself with powerful WCDMA and GSM networking, positioning the place you are and get something you need if necessary. Surely it will save more unnecessary miserableness and trouble.
However, what if you are under the condition mobile phone signal deteriorated while network environment can not be connected contemporary, a built-in compass from first class outdoor smartphone like Somin A9 IP67 can work independently. It can detect the direction change and always guide you the way to the south, which has proved as advisable in the final analysis.
Believe it or not, more factors and elements like protection, waterproof ability and adaptability are needed to be considered thoroughly. However, surely a safe and guaranteed journey will be initiated with the above fundamental functions.
