Any advice on the pros and cons of these types of trap anchors?

What are disposable anchors?
I use Earth Anchors, but retrieve them all. Guess it all depends on your soil type.
Good soil I pound in all 12”. Clay and I’ll anchor about 6-8” in and not in the trap bed. I can use a drill and auger bit and retrieve them in less than a minute. They easily attach with a quick link. Some areas that are known producers I’ll leave them in the deck and use again the following year. Only one anchor is needed regardless of whether I’m targeting coons or coyotes.

Cable stakes are easier to transport and MUCH lighter of course. They can be PITA to remove.

The only pro to rebar (for me) is that its easier to pull, usually. I rarely use it any more except for coons, because I tend to move coon traps around the farm.

Cables also seem to help traps from walking off. Harder to remove than stakes.

Ive been making and using 15" pogos with 2" washers. Make jhooks from 20 penny nails. I have the bender and the mounted crimping tool. I use 7x7 3/32" cable. Costs about $30/hundred.

I use 3/16" quick links to attach trap. On pull day: I cut cable. Reattach another cable stake to trap chain and reset.

Saves my 56 year old back and a whole lot of time. Been using these for few years now.

Still use 20" rebar for DPs set out in the open and a 6' cable extension and half-hitch to a tree in timber.

This is what works for me, but the fact that i am 6'3' 220 lbs and can push rebar into the ground does have distinct advantages.
rebar is much faster i set 300-400 hundred Dp's using rebar, I push them in as far as I can, sometimes i can push them all the way and a simple "stomp' on them as i leave the set is enough. Others i need to pound a couple times, some i have to pound almost all the in.
And I don't need to carry a puller to retrieve them. All I use is a vise grip with a 2ft threaded rod with a tee welded on in place of the adjustment bolt.
My rebar stakes are good practically forever with disposables you may lose some or damage some and therefore you may to replace some.
But 400-500 24 inch rebar stakes weighs a LOT and in some conditions they won't work unless you cross stake and in real sandy they won't work at all.
That being said all I would ever use for canines is earth anchors never rebar, as some animals will "ratchet" rebar stakes right out of the ground.
Good Luck

You asked about disposable anchors, but there are few different types of anchors that work the same way by pounding a piece of metal connected to a chain or cable down into the ground. I started with some of the disposable kind with cable and did not like them. I had two of them fail when driving them into the earth. Must have hit rocks that caused them to deform or break. First one caught a big opossum, but it must not have fought too hard because I was able to pull the cable out of the ground with no effort after I removed the animal. After that experience, I learned to give them a good firm test pull to make sure, and had another one come out broken.

I've since switched to Super Stakes which have a much more robust anchor and use chain instead of cable. I haven't had any problems with those breaking and they can be re-used with some effort. I think you can also get the Super Stakes with cable instead of chain, but I wouldn't want to cut a cable to abandon a Super Stake anchor because they cost more and are re-usable, and if you're going to go to the trouble of digging them up, why not use chain? Chain will also allow you to pull the anchors out with a lot more force than cable.

The advantage of soil anchors (Super Stakes) is that some might argue they hold better than rebar, and it's easier to carry a bucket full of them than several long pieces of rebar. You only need to carry one piece of rebar to drive the soil anchors.

I don't leave sets longer than about 3 days, sometimes up to 5 but its rare, and I have a 24 hour check law, so I switched all back to almost all rebar after using various cable stakes. I use some cable stakes for beaver where its hard to find good ground. A solid anchor is important but some are way overkill.

I use 12 inch Wolf Fangs. I dig up those I can and reuse but if I can't I don't lose one minutes sleep.

Been around the world with earth anchors...Keep coming back to rebar, cross staked...Cheap, durable, easier to pull, better in rocky and frozen ground.

Everybody talks about weight, and my question is, are we hiking or trapping here?...Serious trappers drive right up to their sets, it's faster and more convenient.

If you are packing a driver for your earth anchor, that weighs as much as a rebar stake, so in reality using rebar means your carrying the extra weight of one rebar stake if punching in a single set....Good grief, even a 120 lb pencil neck trapper can handle that, Lol.

I like Pogo’s. They are difficult to pull, which is the point.... They work good for coyote in most soils. Light and easy to drive. I also cross stake with rebar for coyote at times. Both are secure but rebar takes longer and is heavy. Cross staked rebar is not always easier to pull. I have never had a coyote pull either out of the ground. I use short chains.

I use rebar, or usually a cable to a log drag for dp’s and other Coon traps. Pogo’s are too much of a pain to pull as often as I move Coon traps.

Water trapping is more difficult to use pogos for me and I don’t do as much beaver trapping as I do Coon and coyote. I like 30-36” t bars to anchor drowning rigs at the shore.
