I recently bought a Hum 598 cxi, and a chose the 598 model for the price and size.I primarily scan to have something useful to dive after, and use some time scanning and there after analysing the recordings on my pc, which could lead to another scan on sites of special interest.
Just want to share pics of my first towfish. Well I have only a small boat so waves are a big issue when scanning, and it's also much easier to find wooden things be course wood does not give mush echo, but give shadow allright.
Well here it is, nothing much but for me it is actually just a prototype, but seems to be much better than I first imagined.
I have not yet extended the wire, but I have bought 20 meter CAT6 wire for the purpose.
