Functions and Features

After charging the test units for 24 hours, testers ran each radio through a series of bench tests-including transmitter power output, frequency accuracy and stability, and receiver sensitivity-using our Ramsey COM3010 service monitor. All radios in our test group met industry standards with regards to the above tests, although some did it slightly better than others. Testers took transmitter power measurements (high and low power) directly off the radio antenna port.

Feature-loaded VHFs with GPS

The big advantage of handheld VHF radios as compared to their fixed-mount brethren has always been portability. Its portability that allows them to serve as the primary radio on smaller boats (a dinghy for example), as an emergency backup (or secondary working unit) to a fixed unit, or even as a way to summon help during an unexpected swim. While reduced range (due to their shorter antenna height and lower transmit power) have been acceptable tradeoffs for portability, modern handheld VHF radios continue to keep pace with the many other features provided by fixed-mount VHFs.

DeLorme Satcom Solution

We recently had a chance to ocean test the new DeLorme inReach Explorer on a passage from Sarasota, Fla., to the Dry Tortugas in the Florida Keys. Like the original inReach (see Practical Sailor, March 2013 online) and the second-gen inReach SE, the first such standalone device designed to send and receive texts by satellite, the Explorer is primarily a satellite texting device. The Explorer has a small display screen like the inReach SE, but the Explorer features a built-in compass, barometer, and accelerometer to give it some basic standalone navigational functions.

Gadgets Powered by the Sun

Testers recently took a look at two portable solar-powered chargers for small electronics-one of them is new to the market, the Secur Solar Sun Power Bank 4000, and the other, Davis Instruments SolLight SoliCharger 2000, is an updated version of a product we reviewed a few years ago.

The SPOT Sat Phone

SOS buttons and two-way texting are handy, but nothing beats being able to actually speak with someone in the event of an emergency. This is the great appeal of owning a satellite phone, but the prices of both sat phones and service plans have stubbornly remained above the pain threshold most sailors are willing to bear, even though theyve certainly become more affordable over the last decade.

Bad Elf GPS Pro Boosts iPad Nav Apps

Looking to add GPS functions to WiFi Apple devices or increase the GPS accuracy of a Bluetooth device? U.S. company Bad Elf created the GPS Pro, an external Bluetooth wireless GPS receiver and data logger, to simultaneously share GPS data with Bluetooth-capable i-devices, including the iPhone, iPod Touch, and iPad. It also can serve as a standalone data logger that allows you to record up to 100 hours of trip location data.

Nautilus Lifeline VHF

During our recent test of man-overboard electronics (PS, May 2013)-alarms, beacons, and self-rescue devices-we came across a rescue communication product thats been making waves in the diving community: the Nautilus Lifeline marine rescue radio. Being lost at sea is one of the fears that divers and sailors share-remember the 2004 movie, Open Water? The Nautilus Lifeline is a handheld VHF radio that has GPS and DSC capabilities.

Quatix Superwatch

There is no shortage of sailing watches on the market, and weve reviewed our fair share. So when Garmin released its first mariner-specific GPS watch, we were interested to see what features, if any, set it apart from the crowd. After nearly six months of testing Garmins Quatix watch on and off the water, we can report that it is not your ordinary sailing watch. It bundles multiple miniature marine electronics into one small, impressive, hands-free package that is made to withstand life at sea.
