The Messenger Split Standard is a field sampling accessory designed to release or trigger coring and water sampling equipment when lowered down a sampling line. Its stainless steel construction offers durability and resistance to corrosion, making it suitable for repeated use in diverse outdoor conditions. The split-weight design clips securely onto rope or cable and can be removed quickly without retying knots, easing the process of preparing field gear.

In student fieldwork and classroom investigations, consistent activation of sampling devices ensures that students can focus on collecting accurate and representative samples instead of troubleshooting equipment. This messenger weight is compatible with many line-activated samplers and supports the development of systematic sampling procedures in environmental science activities.
