Several times I've wished I had a portable sounder to check entrances to unmarked canals and
anchorages ... Today I saw a humminbird wireless
fish finder (Smartcast)... hook it to the line on your
fishing pole and cast the
remote unit where you want it. The reciever is in a wrist watch LCD plotter, claims a 75ft radius operating range and 100 ft
depth.
I had to get it
Tried it in the pool today and worked well from 8ft to 2ft of
water, even showed the bottom drain cap of the pool.
Tomorrow I'll try it off the shore and dingy to check out entrance to our
canal.
Any one else ever try one of these gadgets ?
