I will probably be doing most my detecting in southern Michigan rivers and inland lakes. A lot of lakes seem to be very murky and I was wondering if anybody has experience in these kind of circumstances. Also, I saw a few guys on youtube with long sleeve shirts and pants. Where can I find water pants and shirts? Amazon just directs me to swim trunks.
MI is great for water hunting. Far less competition than FL and the fresh water preserves relics. I'd begin by practicing in still water with no current. Even knee deep, just so you can learn how to pinpoint and retrieve the target with your scoop. Once you are good enough to do it blindfolded, move on to deeper water or water with waves/currents.
If hunting in waves/currents, careful of wearing waders, as they can fill up and create a drowning hazard.
Wetsuits are available in sizes from fluffy, to huge, to dauuuum! They may be awkward but probably your only solution to hunting in less than desirable temps.
Speaking of temps, if you start hunting year round, you might consider something to keep your detector warm. Depending on the model, freezing temps can impact battery life, the display, and even processor speed.
When the weather breaks, I still suggest you continue wearing foot protection. Fishing hooks, tent takes, broken glass bottles, etc.... are all laying at the bottom.
