Neff, I use the CS24C. It's one step below the Shockwave. It does not have all the whistles and bells. I wouldn't use all that anyway. I am definitely technology challenged. It is the newer model compared to the one gun addict is using. Works great and is on sale right now for $399. Whatever model you get, get the new TX 1000 remote. It is awesome.
Don't over look hand calls. Predatormasters has a lot of custom made call makers that are sponsors on their website that are worth a try.
Critters are over called in my neck of the woods. I have a scorpion that has only called coons and domestic dogs. Im sure my talents are to blame. But I do call coyotes in with hand calls. Don't ask me why that is. It is how it has worked out for me. Anybody want to prove me wrong is welcomed.
Another vote for CS24C. Awesome call and remote. Here is my new one along with an SP-60 Speaker, Mojo Critter decoy, and my two home-made PVC stands.
That looks like a really nice setup!
