They are junk. Very short battery life,10-15 min. short range also. around 100 yards. They lack any power,anything around a 12" bluegill, will give it a serious workout. If the batery is low,you may not get it back. I had one about a year ago,used it in a couple campground ponds. I got tired of chasing it to the otherside of the pond after the battery died. Save your money.
