They are a bit of a gimmick I'm afraid.
They have three drawbacks.
1) The range is very poor - about 30 yards. Some have quoted the wrist mount one having a range
less than a rods length !
2) There is no bottom distinction (grey line) function.
3) They have an angle of view of 90 degrees, so in ten foot depth of water, a fish or feature
showing up on the screen could be anywhere in a ten foot radius of the device - not exactly
smart.

Most of the recent press coverage was a marketing campaign to increase sales, but it backfired
and most of the quality press rubbished it.
I think the consensus is that many will buy one, use it once, stick in the bottom of their
tackle box, forget it and get on with fishing.

Has anyone bought one? Are they any good and which of the models if any are
worth it?
Not thinking of buying one, as I think they defeat skill and experience, but
interested to see what advantage they may give others.
Thanks to anyone answering.
