Laser Guided Temperature Readings

In Boating World Magazine’s May Gear Locker they showcase a nice gadget that allows you to detect above-normal operating temperatures of your equipment.
“Being proactive can help you avoid major problems, including those that may occur in your engine compartment. Telatemp�s pistol-grip IR (Infrared) Thermometer gives an early warning of potential equipment failures by detecting above-normal operating temperatures. Its built-in laser pointer allows you to pinpoint specific locations on machinery. Basic accuracy is +/- 2 percent of reading over a range of zero degrees to 600 degrees Fahrenheit or +/- 4 degrees Fahrenheit, whichever happens to be greater.”
