Up for sale is a new old stock never used Zeagle Flathead VI Regulator DIN - the First Stage only. Purchased a few years ago with the intention to build a double, - never got to it. This is one of the earlier better Zeagle regulators copied from Apex with some improvements. Excellent for cold weather diving. I have used several of them here in the North-East - a pleasure to breathe down to 175' ( have not dived deeper than that). Anyway, if you are looking at this listing you, probably know how it rates. $200. Buyer pays the actual shipping cost. Call or text Rosty at 1 516 361 3392
