Anthony T -- short rod set up.
Here's the short rod. 5 foot stick of 3/8" rerod. There's a nut smashed onto the rerod, looks to be about 24" down from the end. The end that is on the street is the top, The bottom end is in the bed of the truck. The pipe to the left is the "hammer pipe". I have an S-hook attached to the end of a drowner cable. That way the 3/8" rerod can slide through it. Slide it through, push it into the substrate, and use the pipe to hammer it down. Doesn't work in rock.
Here's a shot of that rerod going through the S-hook to secure the end of the drowner cable. This is an older pic and I've changed something since that I'll mention a little later.
You can set these DPs anywhere in a drowning situation so long as there's no entanglement from the trap to the terminal end of the cable.
River dropped a foot plus one day and the eagles had snackums.
Look at the 'coon sign on this bank. I usually have 4-6 Dps on this bank alone.
Now, in this pic there are two sets. One of 'em scored a 'coon as you can see in the water. Both sets have a DP and both DPs are cabled to one terminal short rod. In situations like this I will grab a 10' cable and a 15' cable. Both are anchored at the set location with a 24" or 18" length of rerod, depending on substrate. The longer cable, in this case the 15 footer, is the upstream cable. Wearing chest waders, I will grab one short rod, the hammer pipe, and the ends of both cables. I'll walk out holding the ends of the cables and when both are tight, I'll slide that rerod through both S-hooks and push it into the substrate. Then take the pipe and hammer that down. Remember, the nut with about 24" of rerod above it is the top of the rod.
In the boat there are four milk crates. One has 6' lengths, another 10', 15' and 20'. There's a bucket in the back with "specials" that have 30s, 40s, and 50 footers. In some cases I slide 'coon over sandbars 'til I get to deeper water.
Now, the change to that second pic that I mentioned earlier. You can see how that 'coon can slide all the way to the terminal rod. I've had them power out using the rod as leverage. To solve that I cut off the end and slid a stop onto the cable. Hammered it down and then finished the cable with the double ferrule and an S-link. I've experimented with different lengths and have come up with 30" as a distance from the end of the cable to keep 'coon from powering out. The 6 footers have their stop at 24".
This is what works for me. You can make a hundred sets with 50 short rods in the boat, setting everything in pairs. When I'm trapping deeper water than I can wade out into I incorporate 10' sticks with the same setup. Or go with a drowner weight.
Anyway, for what it's worth.
