How easy is the black paint to chip? Also if you only load say one band does it interfere with the other two when shot
The paint does not chip. The JBL 38 has three bands, the more bands you pull back the more power the gun has. I base this on the size fish and distance from the fish I am trying to shoot.
The bands do not interfere with each other.
Have only used it a couple of times but the paint seems to stick just fine. I have only shot it with one band and it works great with plenty of power.
The black hasn't chipped on mine in 50+ dives. The bands are definitely more powerful than a regular 38.
As with all jbls, the bands are stacked so you can use 1,2, or all three. I usually only go with 2 bands as I'm pretty sure 3 would punch a hole in time.
The gun holds up to abuse pretty well and no if you only load one band the other two will not interfere. In all honesty I almost never used the 3rd band, you could just take it off. A solid gun for shorter distances and smaller fish I have enjoyed it. One thing to recognize is that being metal it always wants to sink so you may think about some sort of tethering system either to a float or your weight belt.
I havent chipped the paint yet...I've owned it over a year now and shooting with one band hasn't seemed to interfere with the others.....here on the California coast we reduce to one band for shootin rubberlips so you don't obliterate them or lodge the speer in something cause they are close shot.
