Dave,
You may or may not be missing out on some detail, or possibly even some lakes in Iowa. The new Navionics Hotmaps regular and Premium will include only 4 regions – North, South, East, and West. But the Premium will offer more detail on some lakes and it appears will also include more lakes overall. As for Iowa specifically, I can’t say at this time because we do not have that level of specifications yet. You could contact Navionics directly and ask to speak to Jeff Brodeur. He should be able to tell you how this effects Iowa.
Our new Premium North chips are supposed to arrive here today, but these are the chip only, no detailed specifications.
Here’s a copy of a recent memo regarding the 2005 release (note that it says that the Hotmaps has over 1000 lakes while the Premium has 3000 lakes):
Substantial enhancements to Navionics’ inland Mapping series, HotMaps, will make the New Year a very happy one for freshwater anglers, plotter manufacturers, and dealers alike.
Fishermen will have three products to choose from in 2005; HotMaps Classic, HotMaps Gold, and the all new HotMaps Premium. These three products will share the same geographic boundaries in the continental U.S-each offering a single chart for the North, South, East, and West. The new 4 Region packaging consolidates the previous 14 HotMaps Regions-offering tremendous value to the customer, fewer stocking items for the Dealer, and ease of distribution.
HotMaps Classic and HotMaps Gold for 2005 will feature the same 1000+ lakes offered in the 2004 version, but 3 or 4 times as many per Region, at the same price! With no loss of detail or performance, HotMaps Classic and Gold 2005 represent a great value!
Navionics newest offering, HotMaps Premium, is the inland mapping system by which all others will be judged. The excitement centers around the inclusion of Navionics’ exclusive high definition survey lakes. These are some of the premier freshwater fishing bodies in the U.S. recently mapped to an unprecedented level of detail and accuracy. Legendary waters like Texoma, Sidney Lanier, Winnipesauke, Beaver, and many more with detail to 1’ depth changes, only available on HotMaps Premium!
Our Premium customers will also enjoy over 2000 new lakes, bringing the lake total to over 3000, and the inclusion of our new Inland Navigable Rivers. We didn’t stop there, also included are many coastal rivers and estuarine systems such as the Everglades, Potomac River, Sacramento Delta, and many more!
Offered in 4 huge Regions on plug-and-play cartridges, HotMaps Premium represents the new standard in inland mapping!
These 3 new HotMaps offerings cement Navionics’ position as the leader in freshwater cartography for 2005. The most lakes, the strongest value, and the finest detail compatible with the best chart plotters…an unbeatable combination. [End Memo]
It might be best for you to get all the details before you make your decision. If I get more info I’ll let you know.
