Mastery MST String TreeThe Mastery MST string tree design is machined (not formed) and features unique hard chrome plating so the strings glide smoothly without the use of moving parts. It has a little more break angle to prevent sympathetic overtones caused by low string tension and less surface area touching the string verses the 50s wing design. Comes with our custom stainless steel screw that's a bit longer as well as our custom made stainless steel spacer. Product

For Professional Outdoors Folks, THIS WORKS!
Size: 5 Ounce (Pack of 1), Style: SPF 50+
I am in the sun approximately 300 days a year and I have used everything available. I am on the water daily and there are only 2 products that 1) work and 2) stay on when wet; Blue Lizard and Doo's. Both have nutrients and moisturizers keeping your skin young. This stuff WORKS! Highly recommended.

Nice sunscreen
Size: 5 Fl Oz (Pack of 1)
Easy to rub in and spread compared to other mineral sunscreens. It goes on a bit white but will blend with lighter toned skin for the most part if you keep rubbing. Provides good sun protection when paired with other sun protection habits and applied regularly! Doesn’t stain fabrics

Better than many expensive options
Size: 5 Fl Oz (Pack of 1), Size: 5 Fl Oz (Pack of 1)
I am shocked at how good this mineral sunscreen is. I am a mineral sunscreen junkie and have so many expensive ($50+ a bottle) high end versions. I have fair/light combo skin and hate greasy, pasty sunscreen. This mineral sunscreen rubs in quickly and isn’t greasy. It out performs MANY high end sunscreens. I love that it has 19% zinc (substantial compared to some others) and is waterproof 80 mins. One thing I found interesting (and awesome) is that iron oxide is listed (last) in the ingredients, which means it has a *very* slight tint. Iron oxide is shown to help block visible/blue light which can be important to people like me with discoloration. This sunscreen is pretty robust for a “basic” drugstore brand. The color is more of a (very pale yellow almost?) off white, not stark white, I think due to the iron oxide listed. I wouldn’t call it tinted, but at least it’s better than paper white sunscreen. In comparison to other thick, heavy, greasy stark white mineral sunscreens, this one is a breeze to rub in! I cannot find anywhere if this sunscreen is nano or non nano, so that’s something to take into consideration if you care, which I really do not. If nano sunscreen is a big concern of yours I would reach out to banana boat to confirm. I purchased this so I don’t have to use my expensive face mineral sunscreens on my body but shockingly this may end up being my new favorite mineral face sunscreen. It isn’t drying on me personally (combo skin leaning oily) and it also wore fine under makeup. The finish is a soft satin after dried down. I’m pretty blown away! It preformed perfect at the pool, even in humidity. I will most likely repurchase. I’m glad to not have to repurchase the more expensive MDSolar science mineral sunscreen I was previously using on my body. I purchased with my own money no paid review! 10 out of 10 for the value and performance from me!!!
