One major thing with predator hunting, is getting set up before you start calling.
Getting set up in daylight is a breeze compared to nighttime and rushing at night makes it almost impossible and is super frustrating, especially when you miss.
Situations like what you had is why I hunt alone 90% of the time.
Rushing and trying to get the kill recorded has taught some dogs and me a lesson.
Buy extra batteries for your NV gear and turn them on before you head out into the field, especially when it's colder outside.
I put my XQ50 on standby, so it's ready to go with a push of a button.
I have shuttered eye guards on everything else to minimize light exposure.
Get a QD rear monopod for your rifle and that'll steady your shot's on the tripod.
You might think your steady, but the recorded media doesn't lie.
Nice work otherwise and it'll only get better with more time in the field to hone your skills.
