Questions:

1. Are you planning to use a commercial coil for the detector or build your own?
2. What sort of performance are you expecting?
3. Do you want to build your own detector because an interest in electronics and how things work, or just because you don't have the money to buy a commercial unit?

Since you have an interest in electronics, and you're planning to build your own coil, then you should really get an oscilloscope. Otherwise it's like having one hand tied behind your back.
