Is it bad for low profile baitcasters made for freshwater to be used in saltwater? Thanks y'all!

Occasional use won't hurt it, if the reel is approved for saltwater no problem at all.  I fish saltwater 7 days a week, at least in my area I see probably no more than 2 or 3 low profile reels being used in maybe a year, and those people seem to be freshwater fisherman coming out to the salt for the day.  We do see some larger conventional reels but primarily those are being used for bait fishing, not steady cast and retrieve.  Once in a while I will see a round b/c being used, still not that popular, spinning is the predominate tool here.  I wouldn't discourage you using a low profile b/c if you're comfortable with it.

 If the reel isn't a salt ready reel, then make sure to have the reel fw rinsed then deep cleaned to make sure all salt is removed each time out.

If the trip is a 2-3 day outing have the reel/s serviced as soon as the trip is over (no matter what kind of reel).

Never let a fw reel that isn't built for salt sit/store without complete cleaning and relube first.

If the reel is approved for salt then deep servicing once/twice a season should be fine....

 

Tight Lines!
