Would a Freestyle snorkel be a good purchase?
i notice that, in one of his videos, Terry used a freestyle snorkel so he could concentrate on a specific technique. I am planning on doing drills on Wednesdays for a couple of hours tore-ingrain my foundation but I was wanting to use a Finis Freestyle Snorkel when concentrating on technique for whole stroke (without having to get a breath). I'm not saying I want to use it every time I swim, just for my drill day (Wednesday). Thoughts and past expereince would be greatly appreciated.
