James have you read the v3 and vx3 manual yet? Have you watched the training videos? Have you checked for a dealer where you can try out a V3i? It sounds like you have not checked how a V3i works. If you are not convinced you want one then asking on a V3i forum is no help.
I understand how things work quickly. I never had trouble navigating the V3i. I borrowed one from Larry and on our first weekend hunt between us we found close to 350 quarters. So it can be a turn on and go detector. (one hunting style)
OK, you asked about setting to your style. Things you can't adjust to your style on the MXT;
Filters - to match your swing speed and mineralization
Recovery Speed - to adjust for open field or trash hunting
Modes - optimized single frequency, 3 frequency, salt mode, salt soil, mixed mode, all metal, stereo mixed mode.
Discrimination - ability to notch
Tones - fully adjustable ( disc out nothing but set some VDI to zero tone.)
Spectragraph - adjust colors, information shown, intensity or consistency base, resolution, base threshold.
That's enough for this question. Find 4 guys and none of us will have the same settings because we all hunt differently.
