Tracking a vehicle, person, pet, or piece of property with GPS was once a technically difficult and costly process. GPS tracking takes the typical functions of a GPS device a step further, by either capturing and storing position data within internal memory for retrieval later, or by transmitting location data in real time via the same cellular data network used by mobile phones. GPS tracking is now very accessible to consumers, for a wide range of purposes. And like so much other technology, GPS tracking has its pros and cons, and ethical considerations, as well. Let's take a look at how it works, and which type of device is best suited for different purposes. Image © Garmin

GPS has long been a favorite tool for fishermen, making it easy to return to good spots. Freshwater  lake fishermen just got another great way to find fish with the introduction of Fishing Hot Spots - Lakes maps ($9.99) from Magellan. "Fishing Hot Spots features extensively researched fishing information including detailed profiles with shoreline characteristics, size, depth and contours, and submerged cover/vegetation to better prepare anglers for their fishing trip," states Magellan. "Lake-specific tips and techniques help the angler identify the fish species, seasonal fishing patterns and the best baits and lures to use for greatest success. Fishing points of interest and other interesting fishery data are included to inform anglers about where particular fish are typically found, primary species and average sizes, tackle techniques and stocking practices."

The maps are sold by state, and are compatible with Magellan's handheld eXplorist GPS devices. Image © Magellan

If you've tried GPS mapping apps and found them to be too complicated, or if you haven't tried trip e-journaling and would like to start logging and sharing your adventures, consider the new GPS Pal app from sportswear maker Columbia. To Columbia's credit, the app appears to be ad-free, and its user-friendly interface made it easy to jump in and start journaling and sharing still images and videos.

Using a big screen is one of the ways portable GPS makers are setting themselves apart from the smartphone competition. If you thought an "oversize" 5-inch screen was large, watch out for this new (shown in photo) VIA 1605TM model with a 6-inch (diagonal) screen from TomTom. This high-resolution touchscreen is designed to provide a large, sharp image of upcoming navigation points, as well as ample space for large, easy-to-find touch zones for controls. The TomTom VIA 1605 TM also features TomTom's folding EasyPort mount, which makes it compact and easy to stow.

"Safety on the road is an ever-present concern for today's drivers," says Corinne Vigreux, Managing Director Consumer at TomTom. "The unique design of the TomTom VIA 1605TM addresses that concern, ensuring that the interaction is easy and instructions are in clear view."

The VIA with 6-inch screen will sell for $229, and will go on sale in late May. Image © TomTom
