I understand that you can order the Garmin Rino 530 from Wal Mart online for $309. That is way below the list price. I believe the reason is that retailers will have the new 520HCX and 530HCX sometime in June. This is a saving of more then $100.00.
I am betting that Garmin will drop the Rino 520/530 in the next year. It is the time for buyers to be aware that these are good items but do not pay full retail. A friend has ordered the Rino 530 and plans on getting a companion HCX model down the road.
For those who use the Rino to track other partners positions the new HCx models with a high-sensitivity receiver will do a far better job, based on my experience with the Garmin 76C which has the same processor as the 520/530 and my 76Cx which has the high sensitivity receiver.
