While lots of devices are limited to in-car usage, a portable GPS system allows for all the mobility you may need. Non-portable devices are usually older models that require cable links, but the same inconvenience is found with combinations of PDAs or Palms and GPS devices that have to be car powered in order to save battery life. A portable GPS system is a unit designed for outside usage either mounted on the bike or motorcycle or carried around when hiking, mountain climbing or jogging. There are some differences between a portable GPS system and the car GPS unit, and although the functions and the features may be the same, what differs is design.

It is of paramount importance to check the calculation time, the ease of programming, the speed of satellite connection, the performance and detour options. Multiple tasks are therefore suitable and available for portable GPS or hand-held GPS units. Always buy a waterproof and weather resistant GPS item if you are going to use it in various temperature and outdoor conditions. The new portable GPS system can also be adjusted to car usage because of the design versatility. You can for example use the GPS device to find alternative routes that avoid traffic jams.

Are there any criteria to be used for the correct choice of the portable GPS system? Comparisons and ratings are available for many models, and the best way to find them is on the Internet. There are in fact, web pages that provide comprehensive comparisons, reviews and price information. The pros and cons of various portable GPS system models are discussed, and some other people’s suggestions could be really useful. Don’t limit the testing of the portable GPS system to the vocal announcements, but go through all the features.

Keep your personal needs in mind in order to identify the relevance of each feature in the portable GPS system. Size is also important for a portable design. If the GPS comes with a screen it may not fit your pocket, therefore, check this portability range too. Then, the price of the portable GPS system should be on your mind. If you are keen on buying a low-priced unit, you could be disappointed when the unit functions only half the time. Automatic rerouting and the possibility to calculate the remaining distance or travel time to destination are equally valuable in a portable GPS.

With a range of hand held GPS devices and a line of marine electronics that carry their tradition of navigation assistance to the marine market, Garmin is a name that is widely associated with GPS systems. They start at $129.99 and go as high as $599.99. Garmin also makes a number of chart plotters with bright four inch QVGA color displays with high speed design for faster map drawing and panning. The chart plotters cost from $499.99 to $999.99.

Along with Chart plotters and GPS navigation systems, Garmin Marine Electronics makes VHF marine radios with features that make them an easy fit to your marine safety package. The Garmin VHF 100 has up to 25 watts of power so that you can make contact regardless of where you are on the water. The VHF 100 has Class D Digital Selective Calling (DSC) capability and can give out distress calls with one click of a button. Boats that have a compatible GPS plotter can use the VHF 100 as a mayday signaling devise which will broadcast the boats location. NOAA weather alerts and position tracking are also a feature of this radio along with the ability to track your friends who are out on their boats in your area.

Also made by Garmin are the VHF 300 AIS, VHF 300 and VHF 200. For 35 foot or larger boats the 300 AIS is designed to monitor all Automatic Identification System channels simultaneously, guaranteeing you never miss a transmission. Also available is the AIS 600 transceiver. It is an electronic device that allows you to receive AIS target data and transmit your vessel information to other AIS users in your vicinity.

The GPH 10, an easy to use autopilot system, is the first in a line of auto guided navigation by Garmin. This system has patented Shadow Drive technology that permits the skipper to maintain control when relying on the autopilot system. There is an automatic Normal 0 disengagement if the helm is turned so that the operator can maneuver the craft. It automatically re-engages if the helmsman holds a steady course. You can obtain as many as three controllers for this autopilot system for autopilot capabilities from multiple places on board.

The TR1 Gold Marine Autopilot is sold only in North America and makes available autopilot on small gasoline outboard boats with motors up to 20 hp. It is truly the first autopilot designed for small boats trolling for fish. With the optional wireless remote you have control over steering and throttle from anywhere on the boat and it can be set to hold its position against current, wind and waves.

Garmin also makes fish finders, sounders, radar, and marine networking equipment in its stable of marine electronics products. Starting in 1989, Garmin has been making navigation and communication devises based on a vertical integration, meaning that they design, manufacture and market their own products. In addition to marine navigation equipment, Garmin makes automotive, aviation, fitness, recreation (camping), and smart phone systems that bring GPS navigation to as many devices as possible.
