What I'm talking about is a hose that comes off of a "T" or much better a "Y" on the high pressure output of your pump, basically it's a small firehose with a control valve at the nozzle. No that is a Hydroforce nozzle, it is used out of the water, it pumps water out onto dry material so you can dredge/suck up dry material, here's a video of Chuck Lassiter the gentleman that makes the Hydroforce nozzle showing how it works.
