I usually go solo on deer hunts...I also learned a lot by making mistakes...bow hunting takes patience and skill...patience waiting for the deer to come by where you can get a shot and skill to execute a good shot! Heres some pointers from my experience...
if you have lots of leaves in your area clear some paths 40 to 50 yds with a rake, foot, leaf blower whatever so they go in front of where you will put your stand...deer will get used to walking the trails because they are quieter...
get proficient at 20-30yds.... you can shoot out to 50yds and some even go to 60+yds but I don't feel comfortable after 40yds...too much adrenaline going for me to shoot that far. also make sure your bow is tuned/sighted in and you wax your strings often especially when you are practicing. keep target arrows and hunting arrows separate. I use the same target arrows. the hunting arrows are the same brand but I never use them for target practice.
if you are in a tree stand try not to move around a lot, bring some quiet snacks and water. if you have to stretch do so slowly, stand up slowly etc. get set up a couple hours before dawn and at least 3 to 4 before dusk...
if you have deer in "range" don't try to draw your bow right off the get go...one you will tire out...two you will prob get busted by the deer. best thing to do is wait for your adrenaline rush and heart beat to fall...then wait for the deer to go behind a tree and then draw your bow. if its the one you are after. I get amped up even seeing one when Im bow hunting! but that's just me...
once you take your shot try to visualize where you shot the deer and if you made a clean shot. If its a clean shot and you hear the deer fall give it 10-20 min . If you think it was a bad shot give it 30 min before you look for blood trail. if it doesn't look like a mortal wound its best to back out and look the next day...that's reason why some like to hunt later in the fall when temps are cooler...you can save your deer that way if nothing gets to it first...
get a decent range finder. range your area where you are hunting so you know the distances...I try to remember where 20yd trees are. that way you aren't fumbling with a range finder when you need to shoot.
also practice shooting from an elevated height...
clear shooting lanes...branches etc may not look like they are in the way from the ground but from elevated position it changes.
turn off alarms...silence phones etc..
wear your safety gear up and down a tree.
get a deer cart...its better than dragging a deer out...unless you cant get the cart in there...me I choose to get a good place where I can get a cart in...dragging 100+lbs of dead weight is no fun!
