I’ve been all over on optics. I’ve got $300 10x42s on my chest, and I’ve had 15s that range from $250-900… some hunts I thought they were great and others I regretted packing them. Same for spotting scopes… got one because I thought it was a “must” and I was left underwhelmed. Then, took it on another hunt and had an amazing experience because of it.
So, that probably doesn’t actually help you at all lol.
Right now, I intend to upgrade my binos on my chest, pack the tripod and pick my spots with the spotter. I do like the idea of the SIGs, but I don’t know that the high magnification ones are the answer.
Obviously if you are truck camping, especially solo, bring creature comforts, all the extra clothes and gear you can dream of, but try and use that time as training to more extreme hunts.
