I've had very little luck trying to use my HD-1250 dipper. 
(Technically, it is a gate dipper, since it uses a FET) I did have some 
hygain traps from a AV-14 that dipped nicely, but my Cushcraft A3S 
traps would not dip at all.

I think the HD-1250 needs tighter coupling to get a good dip than some 
older tube-type dip meters.

For my 80m shut feed on a 15m tower, I used an MFJ-259. Much easier 
than trying to use a dip meter.
