We hire out GL300W GPRS trackers for events. These robust little units are approximately the size of a match box and weigh only 72 grams. They send out their location to the maps at 90 second intervals. This interval can be increased if longer battery life is needed. See the table below for battery life vs message below.

The trackers are GPS units which means they use satellites to work out their postion then they send this information to a LIVE MAP on the web using the mobile network. They use the Telstra Next G Network in Australia which ensures the best coverage in metropolitan and rural areas. They even have coverage out to sea in most places for 20 to 30km! Outside of Australia they roam on local telecommunication provider towers.

We run events in areas deep in the bush where there is little mobile reception. The trackers worked better that we expected getting messages out where we only had 1 bar of reception” Craig Bycroft, director XPD Adventure Race

Tracker Size: 78mm high x 40 mm wide x 22mm deep. Total weight 72g. A little larger than a matchbox

The trackers are not water proof but can be supplied with a waterproof container.

They are rechargeable units and are able to send out messages at the following interval.

Message Interval Expected Battery Life
90 seconds 28 Hours*
2 minutes 32 Hours*
3 minutes 48Hours*
5 minutes 72 Hours*
10 minutes 96 Hours*
* battery life can be reduced by cloud cover, tree cover , being indoors and cold temperatures.

If you require the tracker for a longer event where you will not have access to power to recharge, we are able to supply an external lithium battery in a water proof pelican casing. This greatly increases the battery life of the units.
