Using that radar is an art........and unless you're a R/L radar operator, don't even bother trying to read it yourself.

You'd have to memorize every little "squiggle" that radar line makes in order to determine if you've found a ship or not. Let your Radio op. do that for you.

It's already been said that the radar works best in poor weather.....this is especially true in a blind fog.

I found use for it only until the allies got radar. Once the allies got radar, there's no point in using it since they WILL detect you before you detect them. (This is around early 1942).

After that, it's sonar only (has a decent range of 20 km which is capable of detecting contacts farther out than the early radar).
