I thought I would compile a list on essentials to go SPEARFISHING in WISCONSIN.
WETSUITS: A 5mm "open cell" interior and nylon exterior 2 piece is ideal and you should be able to use it ALL YEAR- the summers may get warm for it- but you can cool down with fresh water. A couple Manufactures I would Recommend: ELIOS, HAMMERHEAD, SPETTON, OMER
MASKS: A Low Volume mask is ideal. But find one that fits good and is comfortable. Avoid masks that are clear on the sides.
FINS: Get a ’Freediving’ fin, Medium Stiffness. My personal favorite fin is "ICE FINS" also Carbon Fins are nice but pricey.
SNORKLE: snorkle is a snorkle- don’t need one with a ’wave guard’ on it around here. just a simple one will work just fine.
WEIGHT BELT: Rubber with a quick detach buckle. You will also need lead weight. Depending on how much body fat you have and how thick your wetsuit is- will determine how much weight you need. For instance I am 200 and wear a 5mm suit I use 23 pounds of weight.
SPEARGUNS: For WI waters I found that 55-90cm is ideal on length. If you were to buy one gun - make it a 75cm. For clearer lakes like LAKE MICHIGAN 90-120 is good. My favorite gun is a 75cm HAMMERHEAD. Other Brands I recommend are: Omer Excalibur, JBL Sawed off Woody, Spetton ALS, Just to name a few. Also, POLESPEARS and HAWIIAN SLINGS give it even more of a challenge
FLOATS: An AB float is nice and holds lots of gear- but I haven’t figured out how to put a flag on it yet. Get a float that is durable and has options to hold gear. You’ll also need a 25’ float line.
STRINGER: You’ll need something to hold your fish. Hoop Stringers are nice- but if you plan on a massacure of Carp get a "Speed Stringer". Also wouldn’t hurt to carry a smaller stringer for those PANFISH you choose to cook up!
That is about it. There are other things you can get to help like: Knife, Underwater Camera, Monofin, Underwater Scooter
