I have been using the Anywheremap since it first came on the market. First with a Casio Cassiopeia E100, now with the Ipac.
It is flat out the best GPS available period.
When ferrying aircraft I use two handhelds, a Lowrance Airmap 300 and the Anywheremap.
PS:
We get to use every system known to man in our business from the Airbus EFIS to the smallest handheld. The airplane I am doing flight testing and training on now has the Garmin GNS 430 and the GNS 530 , but I prefeer the Anywheremap.
