First time searching for yooperlites and this flashlight did the job. What an amazing and fun experience for us!!! So glad I made this purchase. Husband found a monster rock 👍

I had a typical UV flashlight sold on Amazon that cast the purple light. It picks up reactivity, but when I compare it with the Convoy the difference is striking. I want to run to the shoreline right now. The kit is complete with 2 sets of rechargeables and charger, and the sample stone is much appreciated. My husband and daughter, much less interested in rockhounding than I, noticed the difference as well. the grandkids might need their own eventually!
