For most bang for the buck, Deteknix X-pointer for $89. I get close depths as the Carrot, plus or minus 3".
For most features and waterproof, Garretts Propointer AT(Carrot). $127
Splitting the difference is the Garretts Propointer II, $110.
TRX is nice, really deep but I miss the side detection, plus it costs more.
Seems that most people are high on the Carrot. I own them all, plus a couple different ones. The X-Pointer would be my advice for a new hunter at $89.
I'm sorry if I came off pointed before.
***Disclaimer on 3" depths. That's using a nickel. Pointers seem to like nickels for some reason. Dimes and pennies range at 2+ inches.
