No adverse affect that I have noticed. All the change does is alter the perspective for the player, such that you "see" sooner what the crew announces as having "seen" already, and you can assume that an initial announcement is from a lookout in the shears, able to see further over the simulated horizon than you can. In actuality, the AI "sees" through things, like the ocean water at the horizon. The stadimeter, like other aspects of the game, is only as accurate as the computer display allows, as well as the player's accuracy in placing it for targeting...
