Good question ! I can't really tell due to the catch 22 whereby its sensor needs a certain depth of water ( I think about 60 cm , it is in the instructions ) before it can return accurate data. It cannot be tested in an enclosed area eg barrel because that in itself will corrupt the readings . I don't know the depth of the streams around here but they are generally shallow . I wanted this gadget to find the deep pools for me . I didn't want to have to go wading to find the pools in which to test the feckin thing .
But to be more serious -- I had what appeared to muddled / rapidly changing images and data on "live" tests in rivers and lakes . That could of course have been due to a number of acceptable reasons such as speed of drift , depth , nature of the bed etc . I had one short but very satisfactory test in calm , clear sea about 4 m deep. The image showed every rock and corresponded with what I myself could see. It takes a bit of getting used to when compared with a transom f/finder in deeper water but that might be expected .
The main problems are that "no signal" cut short most of my tests and I no longer have much faith in what I receive from water I can't see into .
FWIW When trying the demo mode I had trouble correlating the depth shown with the bottom features displayed in the middle of the screen. . They didn't appear to be in sync . Perhaps that was just me but it didn't help with the confidence factor .
I will be happy to keep it if it can be made to work as well as it appeared to during that test on the sea . Not cheap at nearly £60 stirling but could be a great yoke to have when exploring new water .
I made a mistake on my earlier entry . The p&p charged to my card was actually £26.61 stlg . The refund was £10 .
Finally , and rather belatedly I have checked the customer feedback on Amazon . Water getting in does feature as a problem and I think it is generally accepted by the users that it is their own fault for not screwing the cap on tightly enough . See
http://www.amazon.co.uk/Portable-Wirele ... r_dpwidgetWhen I had this problem myself I gave it a lot of thought because I doubted that I would have been careless enough to cast it out if I wasn't sure it was water-tight. I have found a perfectly "normal" set of circumstances under which water can and does get in even if the user has carefully followed the instructions . Demonstrating that accounts for 3 out of the 4 times water got into mine so I have little doubt that I am correct .
Sorry to bang on . This has been a big disappointment simply because it held so much promise !
I will try to remember to give the supplier a right to reply by sending him a link to this thread ( if that is in order --- Mods ??? Cheers ) .
