LCD screens exposed to sun, spray and chum-smeared fingers get an extra level of protection with DayVue antireflective film ($14.95) from NuShield. The anti-reflective sheets are sized for a range of screens, including models from Garmin, Humminbird, Lowrance, Navman, Raymarine and others. Once installed, viewing is improved, even with polarized sunglasses. The film enhances brightness and contrast of displayed images, protects the screen surface, improves viewing angles and prevents 99 percent of UV light from reaching the screen or reflecting back to the eyes. The chemical- and abrasion-resistant films are simple to apply, easy to remove for cleaning and can be reinstalled. www.nushield.com

Airmar’s GH2183 heading sensor with GPS ($795) combines proprietary dynamic-motion correction software with a three-axis gyro and a three-axis accelerometer to provide maximum accuracy in heading data, helping autopilots steer straighter and radar targets maintain more precise alignment. Expect 1-degree static heading accuracy, and 2-degree accuracy even in rough seas, hard turns and steep heeling up to 30 degrees. The GH2183 outputs both NMEA 0183 and NMEA 2000 data, to interface with a range of autopilots, chart plotters and radar systems. A single purpose model, the H2183 heading sensor ($695), without GPS, is also available. Both are solid-state construction with no moving parts. The sealed, waterproof housing is easily adaptable for either pole or surface mounting. www.airmartechnology.com
The compact, waterproof MR HH125 handheld VHF radio from Cobra Marine ($59.95) has been configured to fill a couple of niches: as the main radio on small fishing boats, or as a backup or personal radio on larger boats. The backlit LCD screen and keypad, with a timed automatic- shutoff to conserve battery power, provide easy viewing in low light. The HH125 offers one or three watts of power. Scan and Memory Scan features locate transmissions quickly, and the Signal Strength Meter keeps tabs on both outgoing and incoming signal. With 10 NOAA weather channels and All Hazards alert, it allows instant access to channels 16 and 9 for emergencies. The case is fitted to accept a speaker or microphone jack to allow connection of hands-free accessories. The HH125 comes with rechargeable NiMH batteries, belt clip, lanyard and DC cigarette lighter charger. www.cobra.com/marine.
