Drown Proofing and mask/fins/snorkel Underwater Knot tying and 30YD U/W Swim Surface Swim with/without mask and fins (500,1000,1500 and 2000yd) Grading Criteria
NEVER HYPERVENTILATE!!! Risk of Shallow water Blackout Always assent in the water column with hand/fist above the head Always brief TTO Always brief emergency procedures EAP Always stay with your Dive Buddy (evolution dependant) Students stay situationally aware at ALL TIMES Brief Expectations of Evolution Over Arching Safeties
Modified Survival Float for 5 min Ankles tied and hands free for 5 min After first 5 min then switch to HOLDING line behind their back with ankles free for 5 min. Hands cannot not let go of rope Unsuccessful students will be removed from tank and receive verbal remediation before their 2nd/3rd attempt. MAX 3 attempts Drown Proofing
Mask/Fins/Snorkel “Ditch and Don Practice” • In shallow end, sit or kneel for 3 min to allow student to become comfortable. • When ready take a breath and submerge to allow the snorkel to fill with water. Return to surface with face in water and exhale forcefully to clear snorkel. Repeat as necessary. • For Mask, in shallow end submerge with mask and then allow to fill with water. • Practice the 2 methods of clearing mask for a minimum of 3 times • Use proper hand signals to communicate with instructor
Mask/Fins/Snorkel “Snorkel Technique” • Using snorkel and fins only swim the perimeter of the tank with face continuously in the water. • Take 1-2 breaths through snorkel submerge and touch bottom of tank and surface, clear snorkel and repeat. • Minimum of 3 laps around pool. • Failure constitutes failure to keep face in water, pinching the nose, does not touch bottom of tank or excessive time on water surface. Remediation will be done in swallow end and allowed 3 attempts.
Mask/Fins/Snorkel “Mask and Snorkel Technique” • This is to be successfully done 3 times in the swallow end and 2 times in the deep end (min). • Drop snorkel and mask not adjoined to the bottom. • Student give “2” to instructor and retrieve mask and snorkel and DON and clear mask using ether 2 methods. • Once Student clears mask student will give “ok” to instructor. If mask needs continued clearing they point at mask to indicate such or given a “4” to indicate to surface. Proper surfacing procedures must apply. • Once at surface DO NOT let face breach surface and clear snorkel and breath normally until instructor gives “ok”
Mask/Fins/Snorkel “Mask and Snorkel Technique” • Once at surface DO NOT let face breach surface and clear snorkel and breath normally until Instructor gives “ok”. • Proper hand signals will be used through out evoluation. • Maximum of 3 attempts. • Failure constitues: Not remaining calm, panic, not giving proper hand signals, not clearing mask COMPLETELY prior to leaving bottom, inability to clear snorkel and breath normally.
Surface Swim with and without fins. • Pool/tank if being used will be set up with fastest to slowest swimmers for first lane to the last. • Using mask/fins/snorkel students will surface swim to the other side of the pool (30m) and then take one breath and swim underwater, along the bottom of the pool back to the starting wall and ascend using proper methods. • Proper hand signals will be used through out evoluation. • Maximum of 3 attempts.
Surface Swim with and without fins. • Grading: Mask/fins/and Snorkel • 500yds is 10min • 1000yds is 21min • 1500yds is 32 min • 2000yds is 45min “Any student displays PANIC Behavior or an inability to adapt to the aquatic environment or presenting a safety hazard to themselves or others will be sent to ARB.”
Knot Tying • Instructors will use mask/fins/ snorkel and will be paired to each student during evolution. • No more than 5 instructor/students pair per evolution at one time. • Instructor will demonstrate evolution prior to execution. • Student will tie a square knot on the first dive and a bowline on the second dive which will be tied to a manifold of scuba tanks on the bottom of the pool. • Once given the ok to the instructor the student untie the knot and safely ascend. “Any student displays PANIC Behavior or an inability to adapt to the aquatic environment or presenting a safety hazard to themselves or others will be sent to ARB.”
30 YD U/W Swim • Instructors will use mask/fins/ snorkel and will be paired to each student during evolution. • No more than 5 instructor/students pair per evolution at one time. • Students may push off shallow end wall to begin and use the breast stroke and glide method following the pool/tank bottom. • Maximum of 3 attempts
Over Arching Criteria • “Any student displays PANIC Behavior or an inability to adapt to the aquatic environment or presenting a safety hazard to themselves or others will be sent to ARB.”
