→Satellite Tracker
* SPOT offers a light weight emergency beacon that when pushing an emergency button submits a distress signal via satellite with your GPS position to a rescue centre. This devise can also be set up to regularly send the GPS position in 10 minutes intervals and to display the hiked track on a map in the internet. We carried such a personal satellite tracker and our families and friends stayed much more relaxed because they could see us move day by day through the mountains. Unfortunately this devise is not particular reliable in Patagonia due to the satellite coverage. Based on our experience only 5% to 20% of the position signals are submitted successfully when hiking in this area. Therefore if you wish to keep your family and friends updated with a SPOT you need to purchase and activate the tracking option while hiking. This ensures that at least some positions are submitted successfully every day. In theory you can manually submit an "OK" message without purchasing the tracking option but this may result in rather long "black-out" periods since many signals don't get submitted successful and the devise itself does not provide any feedback if the signal was transmitted correctly or not. The other limitation of this devise is, that is cannot receive any messages or send messages written on the trail. SPOT requires you to choose one of the annual satellite data contracts so if you need it only for a few weeks or a few months you are forced to pay for more than you acetaully need.

* InReach from Delorme offers a similar devise but without the above mentioned limitations. The inReach uses the more reliable Iridium satellite network that covers in particular the area towards the poles much better what favours its use in Patagonia. This devise also always provides a feedback if the position signal or message was send successful or not and keeps trying until the information is actually received. This devise can send position signals in regular intervals for display on an online map, the inReach is able to send and receive 160-character text messages with the GPS coordinates to mobile phones or email addresses and it can post updates to social media. And when pushing the emergency button a distress message is send via satellite with your GPS position to a rescue centre. The InReach itself is more expensive than a SPOT and it drains the batteries sligthly faster but the InReach is clearly the more reliable option. In contrast to a SPOT devise you do not need to opt for an annual data contact but you can choose the satellite data contract only for the months you really need it. Therefore I consider the InReach from Delorme a much better choice if compared with the SPOT. If you opt for the InReach Exporer and you set it up with the route before the trip than you also have a backup devise for your handheld GPS.
