I got one last year and used it only once. It helps out a little. First I used my reglular led light and found the blood and then switched to the gerber lightto see what it looked like. It did bring out the blood a lot. You could see the blood a whole lot better. But I tried to follow the blood trail with the light and it was difficult. So I switched back to the led and could find it again. It does help you see it better but it is difficult to find the blood if you haven't already saw the blood on the ground. Also, the xenon light that is on the Gerber light is awesome. It is like a mini spotlight. It shines very far. It shines a whole lot better than my led light. Overall it is a good light. If you use a lantern or other means of following a blood trail and it works just find than just stick with that way. It probably wouldn't be worth your $50.
