I agree with jimp on the calls. unless your hunting the rut calling will probably hurt more then help you. especially if you have no experience calling and talking elk. if you are hunting the rut I have always liked wayne carltons super blue diagram as my go to. takes some practice but master it and you can mimick pretty much any sound an elk will make and the only call you will ever need.
vortex razors are pretty nice binos . they may be just a bit much for your budget but if you watch sales you may be able pick one up for 1000. in my opinion . unless you are going to be hunting nothing but forest with low visibility , binos are the one thing no hunter should skimp on. IT is my thought that good glass is the most important item in a hunters arsenal. more important even then the weapon they choose to hunt with.
I understand you are on a budget but would recommend if your looking for $500-$1000 don't skimp . spend the 1000 and if it is at all possible spend more !!!!!!!!!!!!!! good glass is an item you truly get what you pay for .you don't really get in to anything worth owning till you get up to the thousand range. I went through probablt 10 pairs going cheap till I finally got wise enough to spend the dough and get a pair of swarovskis slcs that have lasted me over 20 years ,so far.
go cheap and you will likely be spending it again and again and again .
buy once ,cry once!
