When you need to profile water quality at multiple depths, you want a sampler that can collect discrete samples from different depths in one deployment. The Bacon Bomb fits this purpose because it is a depth-profiling sampler containing several bottles along a line that are triggered to capture water at specific depths as you lower and retrieve the device. Each bottle preserves its own depth-specific sample, making it ideal for comparing layers of water from near the surface down to deeper horizons.

Other devices are not designed for multi-depth sampling in a single run. An Alpha Sampler retrieves larger water samples and can collect sediments at depth, but it isn’t structured to provide separate depth-specific samples along a single profile. The Weighted Bottle Sampler is typically used to obtain a single depth sample from wells, storage tanks, or containers. The DPD Kit is for testing disinfectant residual and not a sampling device at all.
