To determine if you are snagged or hooked on a giant bass, there are a few things you can look for.

First, pay attention to the movement of your line. If you feel a sudden jerk or your line starts moving in a different direction, it could be a sign that you have hooked a bass. Snags, on the other hand, usually don't move or pull on your line.

Second, consider the resistance you feel when reeling in. If you feel a strong pull or the fish is fighting against you, it's likely that you have hooked a bass. Snags usually don't put up much of a fight.

Third, observe any visual cues. If you see a fish jumping or splashing on the surface, it's a good indication that you have hooked a bass. Snags won't exhibit this behavior.

In the video context provided, the angler mentions the fish "running with me" and "going berserk" when hooked, which are typical behaviors of a hooked bass.

However, it's important to note that sometimes it can be difficult to determine if you are snagged or hooked, especially if the snag is heavy or if the fish is not actively fighting. In such cases, it's best to use your judgment and experience as a bass angler.

If you are unsure whether you are snagged or hooked, you can try gently pulling on your line from different angles to see if it moves or if it feels stuck. You can also try applying gentle pressure and see if the resistance changes.

Remember, it's always better to err on the side of caution and assume you are hooked on a fish until proven otherwise. If you are unsure, you can also ask a fellow angler for their opinion or seek guidance from a fishing guide or expert.

I hope this helps! Happy bass fishing!
