What customers say about "Key Specs"
Lowrance Hook-3X (000-12635-001) Sonar
  • Great little sonar for my yak.
  • Perfect for reading depth and temp from small boat.
  • Decent depth finder for the money, I'm able to find brush piles with this unit.
  • Accurate depth readings while trolling around and with motor running.
  • This is not designed for 100's of feet of water. Other more powerful units are made for that.
Humminbird 398ci (409380-1) Side Imaging Combo Chartplotter/Fishfinder
  • The down imaging is great and I could see so much on the bottom even with the small screen size.
  • Easy to install and easy to use. Use on a jon boat in small lake. Down-scan and sides-scan hard to see with small screen.
  • The fish finders and side view work surprisingly well for the price.
  • Good unit. Gets lost with small amount of debris in water, but all in all happy
  • Side imaging at this price is amazing, while you can't see as clear as the marketing pics show, once you figure out dialing in the settings, it's a great structure finding tool.

  • This is perfect for us, great graphics, easy to understand.
Humminbird 398ci (409380-1) Side Imaging Combo Chartplotter/Fishfinder
  • Very clear and readable screen for the size and exceeded my expectations.
  • Obviously screen is tiny. However, has all the bells and whistles and perfect size for ice flasher. Can't beat the price.
  • Small screen but fine for the few times we use the boat.
  • The screen is easy to read wish it was a little bigger. Great price for a fish finder and GPS combo, would recommend to a friend.
  • The main limitation is that the screen is small but that's part of the package so it's not really a complaint.

Humminbird 398ci (409380-1) Side Imaging Combo Chartplotter/Fishfinder
  • The installation took about 2 hours and I am no expert I had to read a lot. Purchase this product with the rig rite tranducer mount if it is a trolling motor mount.
  • Do like the transponder being small so I don't to raise the motor up to see side scan.
  • Very nice unit works great not hard to mount
  • GPS is great for speed, tracking and marking spots.
  • The GPS, side imagining, size, and price all contributed to me purchasing the combo.
