as an avid bow hunter, i was sitting around thinking about how i have plunged my hands into the tank planting plants often up to my elbows often further. well as i have a few extra arrows laying around i looked at the nock area and said to my self that would make a great planting tool. i have used it with great success and will continue to use it. i would suggest going down to wally world and get one and cut the vanes off and use this idea.. pinpoint placing of plants with very little damage and floaters coming out.
just a thought.
