I don't really enjoy all day sits. I will occasionally do it, but rarely. It's just not my jam. Even when I do an all day sit I'll often change stands mid day.
When i went out East i found it very boring sitting in a tree all day!! I would put in 1 air pod with random podcasts to listen to. Probably not the best thing to do but it got me by.
This is terrain dependent, but in my AO even rifle hunting I’m very unlikely to shoot a deer or have a shot at one I didn’t hear first. If I shot one tomorrow that I didn’t hear before I saw it or could shoot it, it would be the first one.
I dub off, I play on my phone, I’ll even close my eyes or stare at a tree. My ears do all of my hunting for me. The second there’s a sound that’s suspect whatever I’m doing or thinking about goes away and it’s 1000% concentration. It’s amazing how well your ears can tell the difference between a squirrel and a deer with near 100% accuracy after you have listened to enough of them.
At least half the deer I’ve shot in the last decade (probably 75%) I was scrolling on my phone when they showed up. To this day screwing off on my phone or otherwise has yet to cost me a deer. I’ll probably cut it out if that ever happens.
4 hours is my absolute sitting still limit & that takes an audiobook & earbuds these days.
Nowadays, I much prefer to pick & choose the perfect wind, weather, moon phase etc.... & go sit for shorter, 2 hour stints.
Oddly, I find myself seeing & shooting many more deer since I started hunting this way, vs just arbitrarily hunting whenever I have 'spare time'
I use my phone when I have signal, even have listened to podcasts, shot a nice tom once while listening to a podcast, even had the phone on speaker no ear buds so I can still hear things around me.
Better chance at killing something while distracted than sitting on the couch!
I am a bit surprised by the responses on this thread. Yes, there is definitely a difference going from active elk hunting mode, climbing up the mountains and being active all day - to passive deer hunting mode, sitting in a treestand and doing nothing for literally hours at a time.
I just got done doing all-day sits for 16 days in a row (except for the day in the middle dealing with logistics and travel to hunt another state.) Outside of that, it was all-day sits for 16 out of 18 days.
I just figure the best way to kill a nice buck is to be on stand. Takes quite a bit of time and energy to hike in (20-60 minutes), setup the climbing sticks and stand (45 minutes), hunt for a couple of hours, and then take it all down again - just to do it again in the afternoon. Also leaves behind quite a bit of ground scent and disturbance.
If I have confidence in my scouting and know that a good buck is in the area, I have no problem sitting all day. If the spot is good, the odds increase of shooting that particular deer. On the rare occasion that confidence is not there, then I will relocate to an area where I know a good buck is in the area. But, that is rare.
To answer the question posed by the OP: how do I manage boredom? I really don't get bored on stand. Just stay alert. Unplug and don't think about life. Just focus on hunting and enjoy being outdoors. Many years ago I used to listen to sports on radio using a portable radio and earphones. Had a nice deer walk underneath me as my hearing was compromised - stopped using the headphones that day. That was about 20 years ago.
