Starting off the weekend of diving with a mola mola visiting the boat at sunset, 12+ ft of viz and 63° water at 20ft. 🍒 conditions and some unique visitors to start off the weekend can’t be a bad sign, cheehooo.

Some people chase the stars in the sky but others know there’s also stars to chase in the sea.

Stay refreshed with your dive skills! Take a look at this textbook giant stride entry demonstrated by Dimitrios — Δημήτρης

For a proper giant stride, the diver has their toes over the edge of the entry point, the right hand (regulator recovery hand) holds your mask and regulator in place, palm securing the ref and fingers holding the mask. Back in the day we always used to say left hand olds your weight belt buckle and gauges to protect them from unbuckling or damage but somewhere along the line some we realized it can also be a good idea to protect the back of your head from accidentally knocking into the tank valve and first stage so the left hand is like dealer’s choice, take your pick. Once you’ve made sure there’s no one in your path on the surface or under the water, make sure to look out at the horizon with good posture (your body tends to follow your eyes so looking down at the water you’re more likely to faceplant which can break masks) and take a GIANT stride away from the boat or entry point, staying mid stride with your legs split until you’re submerged which becomes the perfect time to bring your legs/fins together an a kicking motion to assist you back to the surface.
Once you confirm you have established buoyancy, signal that you’re OK to boat captain/divemaster/buddy.

More divers are comfortable with the giant stride entry making it a far more popular choice if given the option. On Keep-ah you can giant stride or back roll and USA great place to get your practice in and become comfortable with both before you end up diving somewhere that you do not have a choice.

Plus it’s very hard to train this in the pool training and although the general idea is communicated, it doesn’t really allow you to get the full experience and real life scenario practice.

Those low tides last weekend ended up falling right around cocktail hour, maybe that’s a factor in why so many boats ran aground last weekend but on Sunday I was amazed to hear again. It wasn’t necessarily that they happened that was surprising but tha they all grounded along our route back giving us a front row seat to the chaos while not being involved. No injuries were sustained and they were all assisted by numerous emergency vessels keeping them in good hands until the tide lifts them off the bottom.

Someone pulled a gem out of the mud, a torpedo bottle!!

This antique torpedo bottle, made by Cantrell & Cochrane with a unique round bottom design, further impressing with a blueish green color that adds to its charm. The Dublin and Belfast origins of the bottle make it a rare collectible item but the history and origin are unknown.
