Fishing mode. Use this when fishing. The FISH 4500/4600 prominently displays fish, the bottom profile, wrecks, rocks and all the details that help to find fish. Gain and Range are optimized automatically, increasing the sensitivity and fishfinding ability.

Manual mode. Use this to fine-tune the fishfinding ability of the FISH 4500/4600. Best results are often achieved in manual mode, but practice and experience are required to obtain the optimum settings for different conditions. Gain, gain threshold, pulse length and pulse power can all be adjusted. Manual mode stores the most recent settings, so these do not have to be reset each time manual mode is selected.
