One of the many things I love about being a landscape and wildlife photographer is the amount of time I get to spend off the communications grid!  Whether I'm traveling internationally or shooting in our United States National Parks there is a 99% chance I will have zero signal on my cellphone and 100% chance of no WiFi.  I will admit I often dream of being retired and independently wealthy with no time clock to punch and no household obligations however, since none of those is currently true I MUST having a reasonably priced satellite communicator device to keep me connected while I'm in the field! And so, after much deliberation I recently purchased the Garmin inReach Explorer + and I couldn't be happier! Here are a few reasons why: 

1. It connects easily to my phone via Bluetooth so I can text directly through my iPhone 
2. I get up to date weather conditions via satellite  
3. Interactive 24/7 SOS feature for emergencies
4. I track and share my location with family and friends (for me - safety since I'm frequently in the field alone) 
5. GPS on screen routing - love this feature as I can see an aerial view of the National Park featuring me a real time blue dot as I drive to my next location.
6. The interactive Garmin Earthmate App for mapping and tracking.  

You can check out the whole line-up here.  There are so many sizes and options available if you're in the market, I'm  guessing you can find one that fits your needs.
