When approaching sandbars, start off with a large topwater bait and then switch to a subsurface approach. This is a perfect area to observe aggressively feeding fish. The best points are situated with deepwater relatively close to them. In the Amazon or on some South American lakes, deep water is a relative term, as it may mean six feet or might mean a drop to 25 feet. Deep in this case means a significant change from the shallow water near the point.
Peacock bass tend to hold on the deep-water dropoffs of points.
Again, let the fish tell you where they are holding and what they are eating. Sometimes peacock bass prefer long, sloping points that gently taper off shore into deep water. In other instances, they may prefer short, deeper points. I would recommend that one initially fan cast the point with a topwater bait and then switch to a subsurface approach if topwater baits are not producing. The most productive forms also harbor some sort of cover, such as rocks, fallen trees, stumps or brush.
