I got the Whites V3i trigger switch hooked up on my 8500B and it works great. This was my first detector repair/mod project done. I set it up so that I push it forward with my thumb and it springs back when let go. If I pull back on the switch it locks and that does nothing. So it works exactly like the push button would. You can see in the pictures that the switch I used has 3 wires. I only used the red and black wires. That way only the momentary switch works. I didn't have a washer big enough to cover the hole in the top of the handle, so I cut a piece of clear plastic to make it fit. I gotta get a bigger washer and make it better.
