Tip #18: Get a good set of L-rods. For many years I used L-rods that were not all that good. Recently I bought a pair I really like. They are very smooth. When I approach a signal line they slowly start to close/converge. I might take four, five, or six steps before they close completely. For me this is very reassuring. I got the Telerods as they are adjustable length. A case is nice to have to keep away dirt. They are not cheap. I got fast shipping. They sell other rods with various accessories. Check their menu.
