The "Classic" Gun is the style which comes standard with the ATS400 and the JS1000 Ambic Automated Teat Spray Systems. The Classic Gun features an optimal combination of molded plastic and stainless steel components, both for durability and economy. Molded body has a spark (slightly textured) finish and ergonomic shape for improved grip. Stainless Steel lance has an adjustable sprayer tip in contrast with the "Jetstream"-style gun which has fixed nozzle and circular spray pattern. The lever fits closely requiring slight but firm pressure to activate the spray.
