This forward-looking infrared scope may just calm your night fears. It is hand-held or can be mounted and displayed through your chart plotter. Its startup time is a scant few seconds, so it’s as handy as binoculars. Infrared imagery picks up minute temperature differences, making it possible to see navaids, flotsam or especially a man overboard. “White hot” settings give a vivid black and white image of your surroundings. “Black hot” imaging illuminates just the hot spots — like that MOB. The housing is water-resistant. $2,999; westmarine.com
