I let the stand tell me which is best. I hunt a lot of very tight cover alone where you don't see a coyote until he is in shotgun range, a remote e-caller works very well here. More open the country is the more likely I will use a hand call, even more so when hunting with a partner. I do use a Minaska M-1 Bandit allot which is the size of a small bible so packing a e-call isn't a big deal.

I've suffered from asthma for a long time and it has only been since I retired that I can use a mouth call without breaking out into a coughing fit.
After the first shot the rest are just noise.

Make mine a Minaska.
