i have used mine in 18 inches when its dirty mud water off metro beach (lsc Mi.) works fine . You just drop the sensitivity and scroll speed down a bit . Its really unnecessary ,but I get sick of staring down the hole. We have had days when the jumbos are chasing minnows down the shoreline pre-spawn in February and would leave for a half hour and come back . The fish alarm is nice . It tells you when to put down the pop and pay attention. On another bay that is 2-3 foot , the musky spook the perch for a while , then they sneak back in We spear them because they will not bite. Same deal with the alarm.
The new ice pack looks sweet
Are you serious, two and a half feet of water? At that depth you could stare the fish into submission and they'll jump out of the hole. Honestly I wouldn't bother turning mine on under 15 feet, we can see the bottom of the lake in that depth.
