4" coil or 5.75" coil for the Umax???

I've always been a fan of the smaller coil on any of the units i've own. I hunt more trashy areas than anything, so it just makes sense.. My question is, now that i'm in need of the smaller coil for my Umax, do I go with the much praised 5.75" coil or the 4" coil? I haven't really heard anything about the performance of the 4" coil? Is there something about the 4" coil that makes other lean towards the 5.75" over the 4"? Any thoughts would be appreciated!

The 4" is the coil of last resort - the trash has to be monumental. You will not get much more than 4" of depth and it takes a long, long time to cover much ground. You have to overlap the coil, so you are advancing at 2" per sweep.

The 5.75" gets close to 6" of depth (or maybe a little more) and is suitable as a primary search coil. In fact, Tesoro sells a detector with this coil permanently connected. It is good in thick and moderate trash. When you get into larger, more open areas with sparser targets, you'll want something bigger, but for small to medium sized lawns, you could do a lot worse than this coil. Again you have a 50% overlap, so you advance 3" per sweep - or 50% faster than the 4" coil.

Both coils make using a metal detector a little easier. Pinpoints are tighter, targets are easier to separate and enumerate, and digging depths will be mild. You WILL find things that others missed that are hiding in the trash, but you sacrifice depth.

I have both and Topdecker is telling you right. The 4" is pretty limited in depth and coverage, but does a great job in extreme trash or tight places. Generally, I'd say the 5.75 is more usable.

I use a 4 inch coil on my Silver uMax when I go tot lot hunting. The goods aren't deep and I can get the coil rather close to the metal poles supporting the appratus and swings. Also that little 4 inch coil is a little sweetheart for going under benches and the like. You can not live by a 4 inch coil alone, just think of it as another weapon in your arsenal.

Thanks for the responses guys! I was going to just get the 5.75" from the start after hearing of the great results, but figured since there was a smaller option i'd ask before I just jumped on the 5.75". Looks like the 5.75" coil will do me just fine. I do hunt trashy areas, tot lots etc., But I don't think the 4" coil is going to be as effective as i'd like since some of the "trashy" areas I hunt are more than just tot lots, so the extra depth of the 5.75" is more of what i'm looking for. Again, thanks for the comments and info. Now if the snow would melt and the ground would thaw, i'd be ready to hunt!
