Motorola T605 H20 Review

Range and Clarity

The T605 was able to handle up to two miles of range in hilly forests, but at the end of its range, it was more apt to send incomprehensible messages than others. After all field testing, this radio scored about average.

In circumstances where there was a cleaner line of sight, we enjoyed as much as 6 miles of range, though it can be rare in many outdoor environments for a lengthy, clean line. The PTT button has a high and low half, which allows you to decide to transmit at .5 or 2 watts. This feature lets you decide if you want to save battery with lower power, or get better range with higher power. The confusion comes when you are on one of the FRS frequencies that are designated to be at .5 watts. When on those channels, it still will not transmit at 2 watts even if you press the high half of the PTT button. This split button can help you make a longer call when you need it, or save battery, but it can also be unclear as to what power you are transmitting at.

Ease of Use

We prefer interfaces with both buttons and knobs for quick adjustments, but this radio relies only on buttons. Sharing the same arrows for volume, channels, and privacy codes often caused confusion, and even simple changes required menu navigation. In loud environments, adjusting the volume quickly was especially difficult. This all led to a middle-pack score for the T605.

The hands-free VOX feature was not very useful to our testers. It was unreliable as to if it would transmit when you talked, or it may transmit when you were not talking if there was a loud ambient noise. It required you to keep the radio close to your mouth, but its bulky size made this usually uncomfortable. You could use this with the external plug-in earpiece, but the radio is not rated for water use with the earpiece plug open. In real life, this radio's real value comes in its water resistance, so any feature that opens its waterproof ports defeats the radio's value. The T605 has some good features, with plenty of built-in security codes, channels, and weather channels. It also has a flashlight on the bottom to help if you get stranded in the dark, and it has the option of red or white light. The scan function is good if you are communicating with multiple groups.

It also has a whistle built into the backpack clip. However, you have to move a small catch to remove the whole clip to be able to put your mouth on the whistle - something that could be challenging in an emergency situation. The clip worked in most situations, but we could not rely on it to stay secure in the roughest conditions. The spring was just not strong enough; the clip lacked teeth or texture for holding friction, and it seemed prone to breaking.

We were happy to find that the buttons were larger than average, so it was realistic to work this radio with gloves on. It also has an average number of settings and a good display screen, so there are not too many options on the menu to wade through. We also appreciated the simplicity of the battery hatch closure. Making a waterproof door could have easily been over-engineered, but Motorola utilized a simple two-screw design with an effective rubber seal that makes it easy to change batteries.

Weather Resistance and Durability

The T605 performed exceptionally well in our water resistance tests. It met the manufacturer's specifications of being able to spend thirty minutes one meter underwater (with ports closed, of course). It also floats and flashes its light when it goes in the water, which makes it much more likely to be found if you drop it off of your watercraft. This radio is clearly designed to spend time in the water, and Motorola executed that intent well.

The waterproof and floating exterior also works to defend the radio from terrestrial threats such as rocks and getting squashed in a backpack. This radio showed very little wear after our testing, and we have little question it will continue to last. The charging and earpiece ports are the only potential weaknesses to the water-resistance of this radio. If you forget to close them before submersion, you are risking this radio failing. The small plastic pieces on the backpack clip also seem like a likely piece to break with rough handling.

Battery Life

This radio's battery lasts approximately half the time of our review's average. While that was a shorter performance than many others, the T605 has the convenient feature of accepting regular AA batteries in place of the supplied battery pack in case you run out without a way to charge it. This would allow you to extend this radio's life as long as you wanted, as long as you carry enough batteries.

Weight and Size

At 8.4 ounces and 2.5 x 1.5 x 7.5 inches, this is one of the larger radios in our test group. This is not surprising considering the extra material it takes to make it waterproof and float, but it is still a small drawback. When clipped to a backpack or in a pocket, it felt larger and was usually uncomfortable.

This radio is quite blocky and dense, so it felt even larger than its dimensions suggest. It would be better stashed in a storage compartment of a boat or somewhere else that you could keep it off of your body.

Should You Buy the Motorola T605?

If you need a radio to use on the water, this is worth the extra money over cheaper options. A quick dip in the water for most other radios will mean you need to buy another radio, but the T605 won't even flinch if you drop it in. If you don't care about the aquatic prowess of your radio, there are plenty of cheaper options that have similar capabilities and will provide better value for your money.
