Recently I decided to upgrade my compound bow after nearly a year of going back and forth on what I should get. The best advice I can give you is to go to a professional. Find a local archery shop that you have researched and comes highly recommended. There are a lot of people who can provide you with information regarding archery but you need a highly trained professional to make sure that you make the right purchase.
You can cut corners and try and save yourself money by buying online but trust me when I say you are doing yourself no favors at all. Maybe up front you save a little but who is going to set your bow up when it arrives? What is that going to cost you when you have to take it somewhere? Who will set and determine your draw weight? What poundage are you going to be shooting or do you even know? Are you buying a bow that fits you? Is it right for what you are wanting to do? Is the warranty voided if you buy online? Just a few things you need to consider before making that purchase.
Check out your local archery shop. Speak to a professional. Have them fit you for a bow so you know exactly what you need. Find out about the latest equipment on the market. Be informed and make a informed decision because this is a big purchase. Another thing to consider is how serious you are about the sport. Bows can range from $200 to $2000 or more depending on what you add or change out on your rig. You can upgrade almost any aspect of your bow. Are you wanting to get into the sport of archery or primarily going to use the bow for hunting? These are all deciding factors on what bow might be right for you.
Personally I went with the Hoyt Charger Vixcen because I fell in love with it. I loved everything about the bow from the way it felt in my hand to the way it looked. This bow just met my needs for bow hunting with its incredible speed, accuracy and quietness. In my case I changed out the stabilizer, sight and hand sling right from the get go. More upgrades to come too!
I found a trusted professional that I go to for all of my archery needs. They set up everything on my bow all the way down to fitting me for the proper arrows. Safety can never be overlooked and having a professional on your side is always in your favor.
