Garmin Waterproof Fishfinder 300C with 3.5-Inch Display and Dual-Beam Transducer | Marine Electronics

So far I have been very happy with this product.

I use this fish finder exclusively for kayak fishing in Gulf of Mexico, usually a couple hundred meters off the shore. As of writing this review, I have completely flipped the kayak and submerged this fish finder twice. In addition, I have completely drenched it on several occasions when moving through the surf while heading out. So far there are no issues. The rubber buttons seem adequately waterproofed, and the connector that hooks the power cable up is o-ring protected and has blocked water out very well.

This fish finder has a really bright display and shows up great even in direct sunlight. Although I was initially surprised by how small the screen was when I opened the package, I'm very happy with the quality now that I've used it on a couple of fishing trips. It clearly shows battery voltage, water temperature, and depth. The fish depth is clearly marked on the fish icons.

To use this fish finder on a kayak (Prowler Trident 15 Angler), I use a Replacement 12V-7AH. This fish finder will run easily all day on one charge with this battery. For charging I used the Schumacher SSC-1000A Automatic Speed Battery Charger set to normal/small battery settings. I used marine epoxy to mount the transducer to the bottom of a scupper hole. The fish finder by itself isn't tall enough to hold up the Trident's Sonar Shield, so I had to purchase a Anchor Lock W/ 241 Side Deck Mount and cut and file (sawzall and sander) it down so that it basically functions like a small extender for the fish finder mount. See user pictures for details.

The 300C has a small screen compared to many others but it is bright and has high resolution and thousands of colors. The menus are quick and to the point and it has most of the features you will find in higher priced fishfinders. You do need to set it up properly for best results.. i.e. turn up gain, turn on whiteline, and turn OFF fish ID etc. Comes with a fixed mount bracket. I would have preferred the swivel bracket that comes with the FF140, but oh well. Seems to work well and no problems viewing screen even in bright sunlight. Its smaller size makes it an ideal color sounder for small boats with not a lot of room for electronics.

After much time researching fishfinders priced below 300 dollars, I decided this one was for me. Amazon had the best price going and this qualified for free shipping making this an easy choice.
The installation and set up was easy and this unit has performed as expected. I fish mostly fresh water lakes in PA and the Garmin 300C has been a great addition to my boat. I highly recommend this fish finder for those looking for a color unit with temp and great color. Amazon is the place to purchase as the delivery was prompt and product was as advertised.
Enjoy your time on the water.
