it is a hell of a lot easier than free diving
, at least on mine. I have maybe 1/8" clearance between the anode and the hull
. Not the kind of thing you want to "sort of" be okay.
I keep a fine mesh ditty bag clipped to my bc when I'm down there to hold my parts and tools. Small enough mesh that the tiniest part you're working with won't go through it. The bottom is here ultrafine silt. Impossible to find anything that gets dropped.
You're not going to get electrocuted. It's a real risk in freshwater, much less so in salt
(the salt water
itself is much more conductive than you are). If you want to be sure, just unplug the shore power
before you start. One of the guys I get a lot of scuba
advice from is a bottom diver up in SF and won't dive a boat unless he can yank the shower
power in advance.
