I really bang the crap out of my radio and it often sees 20 mph water impact. I never use a bag to protect it. The radio I have now is a year old and has seen hundreds of miles of use in the ocean. I really love the (ABS?) plastic case for its light weight, corrosion resistance, and overall toughness. I have only rinsed this radio in fresh water about 6 times in a year. I usually "put it way wet and salty."

Here is my one year affirmation vote for Icom M32 series handhelds.

dunking a radio

My advise is to smear an ultra thin layer of dielectric grease (tune up
grease, auto parts store; made for spark plug boots) on the charging
contacts, then cover entire charging contact area with either elec. tape
or duct tape. This will prevent electrolysis across the contacts and
thereby will a) save battery life and b) save the contacts from corrosion.

My criticisms:

I wish that the battery was as large as the one on my old Icom Mv1.

I wish that the broadcast and receive quality was as good as my old icom Mv1. (Even so, this M32 is very close to being just as good as the Mv1.)

I wish that the water would drain out of the speaker's bezel a bit easier. (I may drill an extra hole for this.)
