I would choose the Silver Umax over anything else in it's price range, and over many higher priced units. Just my opinion.
I haven't tried all the other lower price range detectors but since I've been detecting for a long time I've used almost all the Tesoro Silver models since about 1983. The Silver has been Tesoro's bread-n-butter machine through the years. It has always sold well and paid the bills for them. I've found very few people who had even the slightest negative thing to say about the Silver uMax model. In my own use of it I found it a coin hunter's dream come true. It can pull wheats from places other machines see nothing. I found it especially good for the copper alloys. It rates very high on silver and gold also.
The Silver uMax with the 10X12 inch concentric coil is as deep as any VLF I've ever owned. It fact when I used it I often found coins deep that my Tejon and Explorer II had missed. They couldn't even get a beep on the coin and the Silver rang out loudly. I don't understand this but it's true.
I know there are those here who say putting a larger coil on a Tesoro doesn't improve depth but try it sometime yourself. Anyone who has been into this hobby for 30-40 years knows that coil diameter and depth are directly related. The larger the coil the less sensitive it is to smaller objects. But the deeper it will go for certain sized objects. Coins are detected well with coils up to about 20" in diameter. The ideal coil size is about 10 inches. This size coil on the right detector should get 10 inches depth on a dime/wheat/quarter. All 3 of these coin types detect about the same depth.
The Tesoro with the 10X12 concentric easily picks up coins at 7 inches and can reach the 10 inch mark if iron masking is limited (ideal conditions). But all detectors regardless of price average between 5-7 inches depth in the real world of detecting because our ground is so full of iron.
I would put a Silver uMax with 10X12 up against any other VLF made today. I personally think the Silver has everything any VLF has to offer that could significantly affect coin/ring depth. Meters, tones, expensive looking materials, etc., are all bait for buyers. Inside the components/circuit boards/etc. are low cost Chinese parts.
Sorry, just a newbie rambling on.
