Wetsuit diving in WI

[oldtimer]

Early season you'll want to preheat.  That is bring a thermos of warm water along and dump it in your suit prior to the dive.  I've used this technique for ice diving and it works well.  Inland lakes are okay until the alge bloom.  Then you might as well migrate to Lake Michigan.  In a 7mm there is lots of good diving from June into October.  It gets a little dicey after that.  Previous years May was good too.  We've had a good old fashioned winter this year though, so May might be a little iffy.  Don't be afraid to try diving early.  You can always come back up.  You might surprise yourself though.  This diving thing can get in your blood.  Have fun and dive safe.
