Product Description

Edition: Additional Sensor

Amazon.com Product Description

With the Humminbird RF45 Advance Remote Sonar Sensor (RSS), you get an even better performance from your SmartCast wireless remote fish finder. This unit provides you with a greater depth capability, and longer in-water usage time than the RSS device that originally came with your SmartCast system. The RF45 features water surface temperature readings, and programmable two-channel operation so you can fish with a buddy without crossing signals, as well as a flashing, internal light that you can switch on or off for night fishing. The RF45 is designed for use with Humminbird's SmartCast RF15, RF25, RF35 fish finders, although it will work as replacement sensor for the RF10, RF20 and RF30 as well, but will not provide temperature readings or extended depth performance. The RF45 is intended for use in the US and Canada only, and is backed by Humminbird's one-year limited warranty.

5.0 out of 5 stars Great device for learning to fish, January 7, 2005

This review is from: Humminbird SmartCast RF15 3.9-Inch Waterproof Fishfinder (Electronics)

Got this as a gift for Christmas when I was shopping with the wife at BassPro here in Orlando. I had been researching these units for a few days after reading about one online. The fact that I could cast out from the shore appealed to me so I chose one of the smartcast models. BassPro had the RF10 on sale and the R15 was the price I had expected the R10 to be so I went with the R15. It includes grey scale and water temp as part of the upgrades from the R10 series.

Over the past two weeks I've taken the R15 out to 4-5 lakes around my area to test it out. Provided I do a nice steady retrive a smooth display of the bottom is presented. I have also seen a fair amount of fish on the display using the Fish ID function. From what I have read on various newgroup posts this feature should generaly be turned OFF. Instead one is supposed to learn how to identify fish using "raw" sonar returns. So far I have not seen any "fish arches". I have a feeling I might need to be in deeper water for this to occur.

Overall the detail is nice and there are four options for displaying the 4 gradations of grey in ordet to highlight either weak or strong returns. One of the limilations of using this near the shore is that is does not do well with shallow depths. It lists 2 feet as the minumum but even depths of 3 feet and a bit more seem to confuse it, giving false returns. I have not tested its actual ability to recognize a return as a fish yet. I say this becuase so far I have not taken my tackle out, just the fishfinder in order to concentrate on learning it. I think I will try adding some bait to a line and attaching this to the small hole provided on the bottom of the RSS to see if it will show any fishing coming up to check it out.

I have had the unit lock up here and there, but unpluging the power cable and reinserting it and then turning on the unit again seems to have solved it. The other day I was getting some weird temp readings, it went from 40F and then back to the correct temp of 71F a few times. I also expienced an anomoly with the display. When set to "Black" mode for bottom detail the unit was only displaying 10H/6V pixels of resolution. Not sure what was up with that and I haven't tested it since then. Perhaps its a battery thing.

Overall I'm really happy with the unit. Sure is nice to be able to see contours of a lake as well as know if fish are in the area. Although the Fish ID might not be perfect you at least know that if nothing is showing on the screen at all to move somewhere else so as to not waste time.

4.0 out of 5 stars Great for the price, June 26, 2008

This review is from: Humminbird SmartCast RF25 1.25-Inch Rod Mount Waterproof Fishfinder (Electronics)

I've now had this little guy for a year and with the exception of the green transducer dying in the first week (replaced immediately by Humminbird), it works like a charm. It's been in both frest and salt water repeatedly without a hiccup. I've had it in as much as 60 feet with fairly good resolution, discerning between weeds, rocks and fish
well for the price. Great little unit for the money, for sure-especially if you have a kayak like me. You won't be disappointed.

5.0 out of 5 stars Little rubber ducky fish finder., October 4, 2007

This review is from: Humminbird SmartCast RF35 Wrist Mount Waterproof Fishfinder (Electronics)

Typical of electronic watches has more features than necessary. By accident and reading the instructions in a canoe it started working in about 5 min. Works great shows fish and structure gives depth and water temp even tells time. Only thing I would change is buttons can get pushed accidently while sleeping or doing everyday chores this throws it into a mode other than time. Usually it goes to fishing mode which according to the instructions runs down the battery at a faster rate as it must act as a radio reciever. If the buttons had been shielded it would be a perfect product. Customer service was great they told me it was water resistant some thing I couldn't find in the instructions. Eventually I plan to use as a bobber/sonar buoy and see the crappie taking the bait how cool is that.
