There are pluses and minuses to both. I don’t know how old your kids are but Matthews make a compound, I believed it is called the Genesis, that grows with your kids. Most compound bows only adjust about 20 lbs or so of draw weight and 3 to 4 in of draw length but tthe Genesis adjusts something like 6″ of draw length and goes from like 30 lbs all the way to 60 lbs. They are a little pricey but it would be cheaper than buying a second compound bow if your kids out grow the first one. Bow fishing is a lot of fun. Ok it’s addictive!!!!! I started doing it a couple of years ago. I just wish I had more time to do it. If you decide to try bow fishing before SHTF check the game laws in your state to see what species of fish are legal to take with archery equipment.
