iFish Pros work well for lakers and pike. As mentioned, you need bobber stops for them.
One tip I have for them is to use an Olfa knife and make a single cut through one side of the red clip where the line goes through so you can clip it onto the line or take it off when not in use. I found it to be a pain to have to hold the loop while I pulled line off and fed a slow sinking dead bait down, especially in 100 FOW for lake trout. This way I adjust the bobber stop to where I want the first time and from then on I can just clip the loop on when I get it down to depth.
You can also pop it off and use the rod normally without having to cut your knots off to get the loop off.
Here’s a pic with the pen tip pointing to the slit.
