For walk in hunts I got a set I let the sand out, and the are really light. Also if I load up my Momarsh with 24 deeks, I go with deeks with no sand, weight makes a big difference.
It certainly does. When hunting the bay we use upwards of 12 dozen. When you do the math and add the decoy, the keel, the weight itself gear ect., you are talking the difference of going safely or not going safely, sometimes. I got a friend that brings a 60 pound backpack of hunting gadgets, 4 boxes of shells. We finally had a chat.
