   * Make sure that payload is going to be easy to spot.  Bright colours perhaps contrasting are good.  Same goes for the parachute.   * Make sure that payload is going to be easy to spot.  Bright colours perhaps contrasting are good.  Same goes for the parachute.

   * If you use a phone for tethering, make sure you have a car phone charger and/or a spare fully charged battery.  Also take a spare phone.  3G + GPS + WiFi will drain your phone battery before the chase is over.   * If you use a phone for tethering, make sure you have a car phone charger and/or a spare fully charged battery.  Also take a spare phone.  3G + GPS + WiFi will drain your phone battery before the chase is over.
   * This may sound obvious, but take a suitable SSB UHF radio with you.  If you don't you might as well stay at home.   * This may sound obvious, but take a suitable SSB UHF radio with you.  If you don't you might as well stay at home.
-  * Also take a magmount aerial for the roof and a yagi.  Check that the radio will have enough battery power for the preparation and chase, and if not take spare batteries and/or a car charger.+  * Also take a magmount aerial for the roof and a yagi.  Check that the radio will have enough battery power for the preparation and chase, and if not take spare batteries and/or a car charger (or use an inverter (12v -> 240v) and your regular laptop power adapter - usually cheaper than a car laptop charger).
   * Take a laptop or netbook or tablet set up with the latest dl-fldigi for decoding, plus audio lead.  if this isn't the same kit you tested with then test it first!  Also, take a car charger to keep that laptop running.   * Take a laptop or netbook or tablet set up with the latest dl-fldigi for decoding, plus audio lead.  if this isn't the same kit you tested with then test it first!  Also, take a car charger to keep that laptop running.

   * Once you can hear the signal, try to get it decoded.  if you can't get a full sentence either stop and get the Yagi out, or drive towards the signal as it gets stronger.   * Once you can hear the signal, try to get it decoded.  if you can't get a full sentence either stop and get the Yagi out, or drive towards the signal as it gets stronger.

-  * Get as close as you can by road.  If you can't see the payload use a handheld GS, or a smartphone with GPS mapping - several offline mapping programs are available so you are still covered without 3G, or a smartphone with a direction-finding program such as "Ham GPS" Take a radio with you (a scanner is ideal) and the Yagi.+  * Get as close as you can by road.  If you can't see the payload use a handheld GPS, or a smartphone with GPS mapping - several offline mapping programs are available so you are still covered without 3G, or a smartphone with a direction-finding program such as "Ham GPS" Take a radio with you (a scanner is ideal) and the Yagi.
   * Note that the predictor does not know the ground height. Predictions will tend to be a few 100m further along than the actual landing. Never rely on a prediction to find the exact payload location, its easy enough to walk past a payload when you know where it is, knowing the location to 100m is as good as lost without a radio   * Note that the predictor does not know the ground height.
