Make sure there is no "dead zone" when reversing extruder directions by hand. Make sure nothing is misaligned or loose. On bowden extruders, ensure that your tube fittings have minimal/no play. It's often faster to just rebuild your extruder than to burn an entire day troubleshooting. Ellis' Print Tuning Guide.

Lifeguards should utilize both scanning patterns to help keep them focused and alert and alternate them every 5 minutes or so. Start by looking at the bottom of the pool or under the water then at the surface. Then scan the activity of the patrons around the beach/pool deck. Keep scanning while alternating your scanning pattern.

Jeff Ellis & Associates, in a 2002 study, suggested lifeguards scan their zone within ten seconds and be able to reach a casualty within twenty seconds. Lifeguard performance should be measured in terms of head mobility as an indication of scanning activity.. 2007), and some even developed "scan patterns" specifically to cover 100% of.

The "Eillis Scanning Pattern" is one of the many scanning techniques taught by the Ellis and Associates Lifeguarding Curriculum. From the YMCA course which I was training by, our scanning patterns where much different, but if theres one thing in common its that our heads will move just like the Lifeguard shown in the video.

Scanning will vary depending on your facility and type of water (pool/lake/beach) the amount of patrons and the amount of objects,features or distractions, the sun and your position of view and the type of zones and other guards zones. There is no 1 "best" way too scan due to the amount of variables.

Incorporate a downward head swing every 10 seconds of your scan. Check All Levels - The pool is three-dimensional. This means when you scan, you must check the bottom, middle, and top layers of the pool, not just the surface. 10 Seconds - Your scanning pattern should take you no more than 10 seconds to scan, and then repeat. Avoid fixation.

This act is known as a five-minute rule and it is a crucial part of our guards maintaining their 10/20 standard and keeping the pool safe. All JEM and Ellis facilities enforce a 10/20 standard which represents the time a lifeguard has to scan their zone in the pool, and then if need be, respond and make a save. The 10 being ten seconds to scan.
