Life Gun / Rescue Equipment

Life Gun
Life Gun

when people play on the ice, they often fall into the ice accidentally due to the uneven thickness of the ice. If the people who fell into the icy water did not get timely rescue, people would be frozen to numb in a short time and sink to the bottom and die. Life Gun can quickly rescue the people who fall into the ice cave by launching a life buoy to the trapped person. The launched life buoy can be automatically inflated into a ladder shape. It can help trapped people more easy to climb, but also increases the stress area on the ice, which can avoid the people falling into the ice water again.
