A review by L5 Imaging Reviews of the Nextorch P86 1600 Lumen Flashlight which comes with a whistle unit... "This is a field test of the NETORCH P86. I want to thank NEXTORCH for sending me the product and making the review possible.
The P86 is both a flashlight and an electronic whistle, combined into one unit. Field testing was performed at the Arbor Hills Nature Preserve in Plano, Texas."
