With how many people are chasing snow geese there is a never ending amount of people flipping spreads on Facebook these days and typically for pretty cheap pricing provided they weren't used for just one season. Skyflys are going to be your best overall decoy IMO whether buying new or used. You will absolutely want at least one caller. Whether you make one or buy one the more sound the better. I wouldn't want less than two even if you may only hunt 1 having a spare or a backup will save you some serious hair pulling. Now here is what I wouldn't do if you are just starting out. Putting together a junk yard spread compiled of 5 or 6 different kinds of socks, building the cheapest possible ecallers, and only hunting fields you have current permission for. Taller stakes are going to save you a super sore back so take that into consideration as well. Maybe it is just me but setting out multiple different kinds of socks/full bodies that all set up slightly different is annoying and if you are just getting started you should do it right. Take this how you want but we've probably tested more amps/speakers than any snow goose hunter in the country and while yes you can build some callers for super cheap I can assure you going super cheap will equal lack of sound quality and volume. While volume is highly over rated, sound quality is not and the cheaper the components you use the more issues you are going to have with them. Which translates into a non working caller 30 minutes before shooting time or an amp that burns out mid hunt that you more than likely have no spare components to fix or trouble shoot. Do what you can with what you have and continue on from there every year. Getting into snow goose hunting can seem pretty overwhelming but I can assure you guys are having phenomenal shoots over small spreads hunting the right conditions and right birds. Either way there is nothing like chasing snows and at the end of the day you should have a blast no matter what!
