Simple rule: Pick a connector rated for at least 1.5x your maximum operating depth. If your ROV goes to 100m, choose 150m+ rating (we&#8217;d recommend 300m for safety margin). Most common ratings: 50m (pools\/shallow), 100m (coastal), 300m (inspection ROV), 500m (offshore), 1000m+ (deep water). Tell us your application and we&#8217;ll recommend the right rating. All our connectors are tested beyond their rating for extra safety.<\/p>\n<\/div>\n<h2>Choosing Depth Rating &#8211; Simple Guide<\/h2>\n<h3>The Golden Rule<\/h3>\n<p><strong>Choose a connector rated for at least 1.5x your maximum depth.<\/strong><\/p>\n<p>Why?
