And it so powerful that the beam itself can be seen for several hundred feet in darkness. Powered by a Sony diode with a lifetime of 3000-5000 hours, it projects a high power green dot up to an incredible 2 miles away. ![]() Our high power green laser pointer features an all-glass lens that focuses the beam to a sharper, rounder, clearer dot. Our all-metal body green laser pointer is therefore robust and durable. Don't be fooled, some green laser pointers have a plastic body that is metalized.

This high power green laser pointer will impress your coworkers, family and friends. We ensure that every high power green laser pointer is hand calibrated and tested to output at least 4.99mw and thus offers the expected stunning power expected of a real constant wave green (532nm) laser pointer, much brighter to look at than a regular red laser pointer and always with a visible green beam. Green laser pointers are fully legal for laser pointer use in most countries and at just below the maximum allowable legal power limit of 5mw for a pointer in most countries. The direct link to the manual for the 1310 is currently. Sentry has the manuals for many of their safes on their support site. Finally turn the knob to the right and stop the first time the final number aligns with the pointer. Turn the knob to the left again and stop the second time the third number aligns with the pointer. Turn the knob to the right and stop the third time the second number aligns with the pointer. Then turn the knob to the left again and stop the first time the third number lines up with the pointer.įor the 4-number combination safes, you start turning the knob so that 0 passes the pointer four times before you stop at the first number. Turn the knob to the right and stop the second time that the pointer aligns with the second number. The pattern to unlock the safe for the 3- number combination models is: turn the knob to the left so that 0 passes the pointer three times before you stop at the first number. The pattern is related to the left/right/left but you have to spin the dial more than 360 degrees on some numbers in the combination. Sentry made safes with 3- and 4-number combinations. ![]()
