Explorer Series is made for the outdoor. Its’ got super long range and a battery life of over 3 hours (most high powered laser pointer only offers one hour of battery life). It is smaller than the Tiger Series yet a bit heavier. The constructions therefore feel a bit sturdier. They are suited for outdoor star grazing, rescue missions and are fun to burn with as well. It uses CR2 Rechargeable Battery and the charger is included. (We cannot ship batteries due to certain international trade restrictions.)
