I've killed hundreds without "fish arrows". I have a containment area at my local res, maybe 2.5 ft deep, cement bottom, has cuts in wall to let lesser volume exit, keeps it pretty constant in level as water rolls over the dam.
There I just shoot my regular hunting arrows, Goldtip carbons. I don't shoot steep angles from me ledge (where the water leaks out). There my feet are right at water level........I take shots 10 ft or more away from me. Back at the slope of the wall it's maybe 15 yards.
It's murder on feathers, but the shafts hold up well.
I had three swimming with arrows sticking out of them, before my bud got his arrow reeled in on his AMS after a miss. Think the slam into the concrete bottom helps stun the fish (outside of that hole they get).
If they do swim off, there's a trick to "landing"
them. I sneak in, and let them swim by. I grab the arrow by the fletch and shove the tip to the bottom hard. I then with a quick flip of the qwrist bring the tip up (after I slide my hand 1/2 way down the shaft).
You'll get a lot of slime and blood on ya, but that's half the fun.
I've also just waded pond/lake edges, creeks, with my carbons. Lose some fish, but not many. There I try to stake the fish to the bank or bottom. Works most of the time..........suprisingly well too.
One thing I did learn...........use a bow you don't mind damaging. I got by with using my SA2 for a good while and then took a nasty tumble. Ended up boogering a limb, they fixed it, but untilmately it needed replaced (held up through deer season).
I love killing carp. I love Blackwidow bows. But I won't be mixing those two again.
BTW, Roger hooked me up with a replacement bow for a very reasonable cost......built to whatever I wanted, since my old handcrafted SA2 wouldn't get the best fit from the new machined limbs. Excellent customer service, in the repair, and later replacement.
