1. Dump the useless external speaker its just dead weight.
2. Include built in X1 probe jack and switch
3. Waterproof to 10 feet, see Garrett AT Pro/Pro Gold e.g. it doesn't have to weigh 40 pounds (cough) Excaliber (cough)
4. Move the main boards back under arm rest with battery with just the screen and buttons out front on a lighter Xterra type shaft. Better balance and less weight is the goal. Keep the thick oval comfy grip like on the Xterra but lose the heavy weight aluminum rod, use carbon fiber instead.
5. Add a small gold mode, tweak whatever you need to tweak to hit smaller gold deeper, smaller gold chains and diamond stud earrings for example.
6. Give me more control over tones, ideally I should be able to highlight an area of the screen and assign a tone of my choice to any targets ID'ing in that area. Rest of screen has normal tone ID's. If I could have 8 of these user definable areas that would be great.
7. The cam clamps on the Explorer suck, when I have to jam a piece of ciggarrett pack into the thing to keep the lower rod from just falling out well there's room for improvement.
8. Option for 10 cell rechargeable AAA to reduce weight.
