Rutus Alter 71 Variable Frequency MD

[HardPack]

Here is a 4 –18 khz variable frequency VLF metal detector that may find a niche in the States: the Rutus Alter 71.

Ziggy Jinx Detector Testing (Facebook: Ziggy Jinx Metal Detecting) is currently testing the Rutus Alter 71 in the UK. MD-Hunter also has a write up (Rutus Alter 71 test. New 2016) which includes several non-translated videos. The Alter 71 was apparently released in the autumn of 2016 but apparently is not yet available in the US. I am not familiar with either the Rutus MD’s or of any US dealers. Non-verified & non-translated video(s) indicate the box may include both  11” DD and 9” concentric coils, control box and housing covers and a 6 cell AA battery pack similar to the Garrett AT series. Battery life is approximately 20 to 50 hours depending on the frequency settings; estimated price US $725 plus; the menu appears to allow you to toggle over to English. The battery door upper insert tabs may eventually break off with use.

The New Rutus Alter 71
[  Website here to show some pictureswww.rutus.com.pl]

…“Some Information here on the Alter 71 I've gathered below.
At the turn of October and November will release a new detector. The name "Alter 71" - from the Latin "other" and the number 71 represents the number of available frequencies.
Alter 71 is probably the world's first metal detector continuously tunable as a function of frequency. The detector is tunable from 4.4 kHz to 18.4 kHz increments of 0.2 kHz - without the need to replace the probe. I know of no current market detector is not possible. The detector is equipped with a radio transmitter digital data allowing such cooperation. With handsets or "wireless headphone jack." Digital transmission has been specially designed for this purpose - does not introduce any delays. 6 hours of battery life "toes" depends on the frequency and ranges from 20 to 50 hours. The detector has the ability to work in a static mode, dynamic or so. mix - the dynamics of the "mixa" can go smoothly depending on the needs.
Graphic display, ID - 120 points, discrimination classical and selective, chart depending on the phase of the signal, automatically tuning to the ground speed control filters ground in a very wide range, the possibility of programming your own sounds, ranges, speed, separation and many other features make the it is a detector at the world level.
The detector has a completely new mechanical design and is lighter than our existing detectors over 200 g.
For the detector probe will be available both DD and concentric.

Regulatory elements:
Discrimination
tenderness
Dyskrymincja selective 120 points
Operating frequency of 4.4 kHz to 18.4 kHz jump 0.2
magnetic stones
Response filters (groundwater) - 8 speeds to choose from
Masking 7 levels
The signal level leading
Ton leading signal
Sensitivity leading signal - regulation allowing for a smooth transition from pure dynamic work to "mix-a"
Strengthening Audio - regulation allows to change the sound characteristics of a dynamic channel and switch it off completely (we obtain in this way the work of a purely static)
Volume
Tony - three sound profiles to search for coins, three to "relics, and three freely programmable by the user
Wireless nature - off, Channel 1, Channel 2
Backlight - 29 adjustable levels
Type of ID - true (depending on frequency), converted to 6kHz, converted to 12 kHz
Hold time - adjustable display time information about an object on the LCD.
Detector has 7 default programs: a deep, deep, large silver, basic, coins, fast, very fast. Factory programs offer a fairly wide cross-section of the possibility of the detector in search of various objects in different conditions. Each factory program can be modified to suit your needs - and the changes are saved when the power is turned off. In case the modifications do not meet user expectations - it is possible to reset each program to factory settings.”

 

 

The Alter 71 target may be only coin and relic hunting. Provided the MD does not demonstrate a frequency preference, the higher frequencies up to 18.4khz puts this MD tin he small nugget range on ground within the VLF limits.  Perhaps this will excite future development of a variable frequency MD with fixed steps with a 3kHz to 48khz range.

Shelton recently posted that he is also testing the Rutus Alter 71 and provided the following link: http://www.rutus.com.pl/page/19/alter-71.  Hopefully, he will provide future updates on his testing & review.

For now I'm hanging on to the MLX705; other than wait and see; any thoughts on variable frequency VLF MD’s for coin, relics and nuggets?

The main issue will be manual ground balancing only, without any ground phase offset. No automatic tracking also. This is very fresh version and I'm kind of beta users. But machine works very good. You have separate adjustments for discrimination channel and static. Like in Whites machines..Stable clean without chattering, no EMI too, even under high voltage lines.

Relic program is kind of mixed (mono) mode. I will talk about prospecting with manufacturer option.

I'm still testing this machine. Now we have winter here...
