Data from acoustic backscattering provided estimates of abundance and changes in the vertical position of scattering (= aggregation) layers.Why Vertically Split?A vertical split closes one of those gaps, so the ring applies pressure more like a hose clamp. The bottom screws are tightened, mechanically closing the bottom gap. This means that the top of the ring must flex and conform to the scope tube when you tighten the top screws.
