Scubamax Pony Bottle Pressure Gauge

Initially i wasn't so sure if this would turn out well, but after i received it and attached it onto my regulator 1st stage and onto my dive tank, it worked like a charm. I clean my boat hull twice a month and i leave my tank on the boat and just get into the water with a 12 foot hose and 2nd stage. As i didn't need a BCD and full reg setup, this was the perfect gauge to let me know how much air i have left in my tank. I recommend this product.

Have had this gauge on a pony bottle reg that I use around the house so it has not seen water. So far the gauge has worked well.
