Wow. Your just like me, buddy! I’m your age, and started detecting with a vaquero for all the reasons you stated back in 2013. Well, and we found a 1853 seated liberty quarter one day in my in-laws sunflower patch...which started an addiction
But, I just want to say, your doing yourself a huge injustice by not branching out with at least one machine. The vaquero is great, it can do most anything you’d ever need really. I spent 5 years with mine and still have it. It found me some really cool relics.
After many hunts on my usual short hunt time frame, I got super frustrated with digging deep iron and having to dig trash. It is great on old plowed field homesites loaded with iron, say uninhabited no later than the 20s or 30s where everything is just cast through the first few inches of soil, up to 6” or so. I found tons of goodies out of dense iron from mid 19th century farms with the 5.75 concentric.
Then I found a good deal on a T2SE with 5 coils and I knew of its relic rep. I bought it and the vaquero sits. That thing will dust the vaquero in nearly every hunting situation I encounter except high EMI areas. So I started buying up FT machines, a GBP, an Omega 8000 v4. The T2 and Gold Bug Pro are nearly irreplaceable in my book.
All that being said, I still have the vaquero for a reason. It’s fun to use when I have time to use a small coil and dig all deeper sounding targets above iron. And it will hang with the t2 in moderate iron but it won’t see the deeper small stuff way below iron like the t2 sometimes can. It’s a good fun machine, it my good finds increased with others. Now I’m wanting to try the vista x. Seems to me it would answer the vaqueros weaknesses nicely. This is all my opinion, good luck man.
