Amazon.com Product Description:
Keep on top of emergencies while staying in touch with other boaters with the Standard Horizon STD-HX600S handheld two-way VHF radio. Specifically designed for marine use, the HX600S is factory programmed with all U.S., Canadian, and international marine channels, keeping you fully informed of all the latest oceanic activity. At the same time, the radio receives a host of weather channels from the National Oceanic and Atmospheric Association (NOAA), so you can learn about approaching storms or hurricanes well before they hit. And should you want to sing along to your favorite song while you sail the open seas, the HX600S can handle that, too, as the unit receives AM, F.M, and aeronautical bands to give you a ton of listening options. You can even listen to the HX600S on dry land thanks to the built-in 700 mW speaker.

As with any well-built marine radio, the HX600S is rugged and fully submersible, with an impact-resistant polycarbonate chassis that can withstand submersion in 1 meter of water for 30 minutes. Users can also diversify their scanning functions with the Dual Watch mode, which lets you scan a selected channel and emergency channel 16 simultaneously, and the Priority Scan mode, which lets you monitor several channels at once. The Dual Watch and Priority Scan modes are essential for safety-conscious boaters who don't want to miss a potential distress call.

In addition to offering an NOAA weather alert--which automatically switches your radio to the appropriate weather channel when nasty weather approaches--the radio can also receive and display NOAA S.A.M.E. broadcasts. S.A.M.E. messages including warnings and post-event information for all types of hazards, including natural disasters (such as earthquakes or avalanches), environmental disasters (such as chemical releases or oil spills), and public safety emergencies (such as amber alerts or 911 telephone outages).

Another nice feature is the NMEA charging cradle that lets you connect the radio to a GPS. Once connected, the radio stores your GPS location in its memory, and then notifies the Coast Guard or other emergency service should an accident occur. Other operational details include a dedicated emergency channel 16/9 key, user-selectable transmit power (2.5 watts or 1 watt, depending on the circumstances), an audio port for connecting an optional speaker microphone or headset, a backlit keypad with an extra-large display, and a high-intensity strobe light that emits the internally recognized S.O.S. signal during emergencies--a must for any boater. The S.O.S. beacon can be seen from up to 1 mile away.

When you're not using the radio, simply drop it in the cradle, which will keep the rechargeable NiMH battery operating at full capacity. And because dead batteries can be a serious safety hazard on the water, the HX600S sports a battery life indicator on the LCD that warns you when the battery needs charging. The HX600S, which includes both AC and DC chargers, measures 2.36 by 4.09 by 1.2 inches (W x H x D) and is backed by a three-year warranty.

Product Description:
These sleek 440-series Garmin plotters pack a lot of value into their space-saving formats. They feature ultra-bright 4" QVGA displays and come ready to launch right out of the box with built-in cartography, new worldwide satellite imagery and a new streamlined user interface. The 440-series is preloaded with highly-detailed BlueChart g2 marine cartography of the coastal United States - including Alaska, Hawaii and the Bahamas. This data provides detailed coastlines, shaded depth contours, navaids, port plans, wrecks, restricted areas and tide and current information. The powerful built-in analog sounder found in the 440s and 440sx can scan as deep as 1500' (in dual frequency mode) and features UltraScroll for high-speed screen updates. The 440s and 440sx also offer split-screen viewing of map and sounder data for easy, continuous reference. The 440x and 440sx come with the GXM 31 Smart Antenna. With a subscription to XM Satellite Weather, the 440x and 440sx can provide continuously-delivered weather on the unit's high-resolution sunlight-readable display. Vital weather data, such as NEXRAD radar, forecasts, and current conditions is graphically displayed directly on the chart - so you can spend more time enjoying the water and less time worrying about the weather. Plug in optional BlueChart g2 Vision cards to add true 3D-view detailed mapping capabilities (both above and below the waterline), plus helpful auto guidance, high-resolution photomapping detail, and "real picture" aerial photos of ports, harbors, marinas, waterways, navigation landmarks and other points of interest.

Amazon.com Product Description:
The Garmin GPSMAP 540s Chartplotter with Dual Frequency Transducer provides a versatile chartplotter for those with a keen eye for value. With plenty of built-in functionality and compatibility for upgrades or expansions, the 540s is the perfect companion for any boater looking to get out on the water and start exploring, or to simply plot a safe course from point A to point B.

The Garmin 540s chartplotter uses a crisp, ultra-bright, full-color 5-inch QVGA display with 640 x 480 pixels of resolution and over 800 nits of brightness that lets you easily distinguish bottom detail and fish from background structure. The 540s lets you view your position with pinpoint accuracy to within less than three meters via its extremely accurate, WAAS/EGNOS-enabled GPS antenna, and comes with a built-in, satellite-enhanced worldwide basemap, as well as detailed offshore maps with BlueChart coverage of the USA and Bahamas. What's more, with an SD card slot providing compatibility with the optional BlueChart g2 Vision card, you can further enhance this unit's mapping capabilities with features such as high-resolution aerial reference photos for help navigating tricky harbors and channels, or locating spots like area marinas or fuel stops. The g2 Vision card also lets the 540s provide graphical depictions in a true 3D mariner's-eye topside view, or fish-eye underwater perspective.

The Garmin 540s features intuitive navigation with fewer buttons to push and operational steps to traverse, and a simplified menu format that makes it easier for you to see and select the data you want to access on-screen, as well as a tilt and swivel mount bracket that lets you set it for optimum positioning. The 540s also features a backlit keypad for easier operation at night, and a new night mode function that provides optimum readability in low-light conditions. The 540s can also provide auto guidance via the optional g2 Vision card, which searches all your chart features in order to suggest the best known charted route for navigation, so you always have a knowledgeable guide to local hazards and waterways on deck with you.

The 540s is designed to be easily adaptable to various conditions with a choice of dual-beam or dual-frequency sonar to clearly portray depth contours, fish targets, structure and more. This unit comes with dual-frequency, 50 kHz to 200 kHz transom-mount transducer with a narrow beam that pierces the depths for maximum saltwater performance. Made to be upgradeable and expandable, the Garmin 540s includes built-in CANet connectivity that enables its sonar data to be shared with other chartplotter displays on your boat. This unit weighs two pounds, and measures just 6.4 x 5.9 x 2.9 inches (W x H x D) allowing it to be placed virtually anywhere.
